Cold Email Statistics & Benchmarks 2025: How This Year’s Stats Compare to 2024

Major Takeaways: Cold Email Statistics

Cold Email Failure Rates Are Still High

• About 95% of cold emails fail to generate replies, with average response rates between 1% and 5%—emphasizing the need for stronger targeting, timing, and follow-ups.

2025 B2B Email Benchmarks Declined vs. 2024

• Average cold email open rates dropped to 27.7% from ~36% the previous year, while reply rates fell to 5.1%, highlighting the growing challenge of breaking through inbox clutter.

Deliverability Is a Top Priority for Success

• Around 17% of cold emails never reach the inbox, often due to poor domain authentication, high bounce rates, or spam-triggering language—making technical setup mission-critical.

Personalization Drives 2–3X Better Response Rates

• Campaigns with advanced personalization (beyond first name) saw reply rates up to 18%, double the average of generic templates—only 5% of senders personalize every message.

Follow-Up Sequences Significantly Increase Engagement

• Cold email reply rates improve by 50%+ with consistent follow-ups, yet 48% of reps never send a second message, missing key opportunities to re-engage.

Timing and Channel Matter More Than Ever

• Emails sent on Monday or Tuesday at 1 PM outperform other times, and outreach that combines email with LinkedIn and phone can boost results by over 287%.

Omnichannel Strategies Outperform Email Alone

• Cold emails backed by LinkedIn touches and strategic calls yield stronger engagement—multichannel outreach consistently beats email-only sequences.

Conversion Rates Are Low—But Optimizable

• Cold outreach conversion rates remain around 0.2%–2%, but well-targeted campaigns using personalization, social proof, and strong CTAs outperform industry norms.

Introduction

Cold emailing isn’t dead – but it is tougher than ever. If you’re wondering why it feels so hard to get a reply these days, the data tells a clear story. Most cold outreach messages never get a response. In fact, only around 5% of cold emails succeed in getting any reply – meaning about 95% fail to spark engagement (1). In 2025, flooded inboxes, smarter spam filters, and savvy B2B buyers have raised the bar for cold email success.

So what’s changed in 2025, and how do this year’s cold email statistics stack up against 2024? In this article, we’ll break down the latest B2B cold email benchmarks (opens, clicks, replies, conversions) and explore why the vast majority of campaigns fall flat. More importantly, we’ll provide actionable insights on how you can join the successful 5% that do generate sales leads and meetings from cold outreach.

B2B Email Marketing Benchmarks 2025 vs 2024: Key Cold Outreach Metrics

To understand the uphill battle in cold email, let’s first look at the core B2B email marketing benchmarks and how they’ve shifted from 2024 to 2025. The numbers paint a challenging picture (1):

• Open Rates: The average open rate for cold emails dropped from ~36% in 2023 to just 27.7% in 2024 (1). That’s a significant decline in eyeballs on your messages. Overall email marketing open rates (including warm campaigns) have hovered around 42% in recent data (8), but cold outreach sees much lower opens. By 2025, a 15–25% open rate is considered an acceptable range for cold B2B campaigns (1). In other words, if one in five prospects opens your email, you’re about average. Higher open rates are increasingly hard to achieve due to factors we’ll explore (like privacy rules and inbox filtering).
  
• Response Rates: Getting opens is hard – getting replies is harder. The typical cold email response rate is only about 1–5% (2). In 2024, one industry study pegged the average cold email reply rate at 5.1% (1), down from roughly 7% the year before. That aligns with other research showing only ~8.5% of outreach emails get any response at all (3). Put simply, about 19 out of 20 cold emails get ignored. These low response benchmarks have carried into 2025. Our conversations with B2B outbound sales teams confirm that a “good” reply rate today is anything above 5% – hitting 10%+ is an excellent result in most industries (13). We’ll discuss what “good” looks like and how some teams beat the odds.
  
• Click-through Rates (CTR): Cold sales emails aren’t primarily aimed at getting link clicks (the main goal is usually a reply or meeting), but CTR is still tracked. Average email marketing click rates tend to be low – around 2% across campaigns (8). For cold emails specifically, click rates hover around 3-4% on average (1). This means that even among those who open your email, only a small fraction click on links or call-to-action buttons. If your cold email includes a link (say to a case study or signup page), a few clicks per hundred opens is normal. Don’t be discouraged by small numbers here; often, generating a direct reply is a more relevant success metric for cold outreach than raw CTR.
  
• Conversion Rates: Ultimately, the goal of outreach is to convert prospects – whether that’s booking a meeting or closing a sale. Conversions are the ultimate measure of success, but cold email conversion rates are tiny. A recent analysis found an **average cold email conversion rate of just 0.2% (about 1 deal won per 500 emails sent) (12). Even “good” cold campaigns might only convert 1-5% of prospects into customers or qualified opportunities (1). For perspective, a 2% conversion rate is considered solid in B2B, and 5% is exceptional (1). These numbers underscore how much volume and persistence it often takes – and why any improvement in response rate can yield significantly more revenue. (As we’ll cover later, multi-touch cold email sequences and personal engagement can bump these metrics up.)
  
• Bounce & Deliverability Rates: Another unglamorous but crucial benchmark is deliverability – what percentage of your emails actually reach the inbox. On average, about 7-8% of cold emails bounce (fail to deliver) (4). This is higher than the <2% bounce rate typical in opt-in email marketing (11). Bounces and spam filtering mean that roughly 16.9% of emails never make it to the inbox at all (1). If one in six of your prospects isn’t even seeing your message, that drags down all other metrics. Ensuring a 95%+ deliverability rate is a key focus for top performers (more on how later). Also note that unsubscribe rates in cold email are usually low (since many emails aren’t even opened); an average cold email unsubscribe rate is around 2% or less (4), which is normal and indicates compliance with opt-out laws.

A quick visual idea: It may help to include a chart comparing 2023 vs 2024 cold email open and reply rates (e.g., a bar for 36% vs 27.7% open rate, and 7% vs 5.1% reply rate). This would illustrate the decline year-over-year. 📉

Interpreting the Benchmarks

These benchmark stats might seem discouraging – if only ~25% open and 5% reply, the vast majority of your cold emails are indeed failing to engage. But don’t despair. Benchmarks are not destiny. They’re averages across many companies, including those blasting out generic spam.

If you’re strategic, you can outperform these averages. For instance, while ~5% is the overall reply rate, some well-targeted outbound campaigns achieve 15% or even 25% reply rates (2). And while 27% is the recent average open rate, highly compelling or well-targeted emails can still see 50%+ open rates in 2025 (especially within smaller, curated prospect lists) (4).

The key is to understand why most cold emails perform poorly, and what the successful outliers do differently. Let’s examine the trends behind these numbers and the new challenges emerging in 2025’s cold email landscape.

Why 95% of Cold Emails Fail in 2025 (B2B Email Benchmarks & Trends)

It’s often said that “cold email is a numbers game.” While there’s truth to that, sheer volume isn’t a winning strategy anymore. In 2025, quality beats quantity. The reason 90–95% of cold emails fail comes down to a combination of factors. Here are the top causes, backed by benchmarks and insights, explaining why most B2B outreach emails never make an impact:

1. Tougher Deliverability and Spam Filters

Reaching the inbox is the first battle – and it’s getting harder. Email providers have become extremely sophisticated at filtering out unwanted emails. With over 160 billion spam emails sent daily, filters now divert nearly 1 in 5 emails straight to spam folders (1). If your cold email doesn’t have proper authentication or shows red flags (mass-blast behavior, spammy wording, etc.), it may never be seen. Recent Gmail security updates and Apple’s privacy changes also mean open rate tracking is less reliable, and some legitimate emails get misclassified. As a result, many senders see declining open rates through no fault of their own. About 17% of cold outreach emails never reach any inbox at all (1), vanishing due to bounces or spam filtering. This deliverability barrier significantly contributes to cold email failure rates.

2. Low Open Rates – Getting Lost in the Noise

Even if your message is delivered, getting a busy prospect to open it is another major hurdle. The average cold email open rate in 2024 was just 27.7% (1), and only 23.9% of sales emails are opened on average according to Gartner data (3). That means roughly three-quarters of your recipients delete your email (or ignore it) without reading a word. Why so low? One big reason is inbox overload. Decision-makers in B2B get bombarded with unsolicited pitches – often 10+ cold emails a week, most of which are irrelevant to them (1). Prospects have become adept at filtering their own inbox, prioritizing only messages that seem immediately relevant or at least intriguing. If your subject line doesn’t grab attention or your sender name isn’t recognized, your email may never get opened. Timing plays a role too: Emails sent on weekends or off-hours often languish unopened. Data shows Monday and Tuesday tend to have the highest open and reply rates (e.g., 22% open rate on Mondays, the top day (3)), whereas Fridays and weekends yield minimal engagement (3). Many cold emails fail simply because they arrive at the wrong time or blend into the Monday morning deluge. Without an effective strategy to stand out, the odds of an open are slim.

3. Weak or Generic Subject Lines

Your subject line is essentially your “first impression” – and many cold emails fail right here. A staggering 33% of recipients decide to open or delete an email based solely on the subject line (3). Worse, 69–70% of people will mark an email as spam just from the subject line if it looks sketchy or irrelevant (3). Common mistakes include using spam-trigger words (“Free money!!!”), being too vague or salesy (“Increase profits fast!”), or just not piquing interest. If your subject line doesn’t communicate value or at least curiosity, your open rates will suffer. This is why generic sales email templates often have abysmal opens – they lack personalization or relevance from the very first glance.

4. Lack of Personalization & Relevance

Perhaps the #1 reason so many cold emails fail is that they feel like cold mass emails. People can sniff out a templated, one-size-fits-all message instantly. If your outreach is not personalized or tailored, it’s likely headed for the trash. According to data, adding even basic personalization can dramatically change outcomes. Generic cold emails might see ~9% response rates, whereas those with “advanced personalization” (tailored to the recipient’s context) see about 18% response rates – double the generic rate (1). Another study found highly personalized campaigns (using multiple custom fields) boosted replies by 142% compared to non-personalized blasts (3). Despite this, the vast majority of senders don’t personalize enough – Mailshake’s 2025 report notes only 5% of senders personalize every email, and those who do get 2–3X better results (5). The takeaway is clear: most cold emails fail because they talk at the recipient with a cookie-cutter sales pitch, rather than to the recipient about their specific needs or pain points. In B2B, an email that isn’t relevant to my business problem won’t get a reply, no matter how many you send.

5. Poor Targeting (Bad Prospect Lists)

Even masterfully written emails will flop if sent to the wrong audience. Another hidden reason behind that 95% failure rate is poor targeting – many email drip campaigns cast too wide a net or use outdated/low-quality data. If out of 100 contacts, half aren’t truly qualified or in the right role, of course your success rate drops. The 30/30/50 rule of cold email states that 30% of success comes from your content, 30% from your prospect list quality, and 50% from your follow-up strategy (6). That means list quality is as important as your message itself. Unfortunately, it’s common to see teams purchase giant lead lists or scrape emails without much filtering, resulting in irrelevant recipients who were never likely to respond. Additionally, bad data leads to higher bounce rates, damaging sender reputation. Many of the 95% failing emails are simply going to prospects that don’t fit the ideal customer profile or don’t have the authority/interest to act. Tight targeting and list hygiene are often neglected, to the detriment of campaign performance.

6. No Follow-Up (Giving Up Too Soon)

A single cold email is rarely enough to get a busy prospect’s attention. In fact, industry statistics show that 80% of successful sales require five or more follow-ups after the initial contact (9). Yet a huge portion of salespeople never follow up even once – nearly 48% of reps don’t make any follow-up attempt if the first email goes unanswered (9). And 44% give up after just one follow-up (9). This lack of persistence means many potential conversations never happen. It’s no surprise most cold emails fail when nearly half of outreach sequences are only one email long. Follow-ups make a big difference: sending a second email, a third, etc., significantly improves your odds. One study found that simply sending a single email follow-up can increase reply rates by 22% in some cases (3). Backlinko’s massive outreach study showed emailing the same contact multiple times led to 2X more responses overall (7). Our own experience confirms that polite, well-timed follow-ups (referencing the initial email and providing additional value) will capture prospects who missed or ignored the first email. Most cold outreaches fail by stopping too early. Persistence (without pestering) is key to join the 5% who succeed.

7. Content Doesn’t Deliver Value

Let’s say your email does get opened – now the content needs to hold their attention. Here, too, many cold emails fall flat. Common pitfalls include: too much focus on the seller’s company (“We are the leading provider of…”), not enough focus on the prospect’s problem; emails that are either too short to convey substance or too long and rambling; and lack of a clear call-to-action. Interestingly, data suggests that ultra-short cold emails aren’t always best. While being concise is good, emails with ~4-5 sentences (around 150 words) actually achieved 15X higher response rates than very short emails (4). Why? Likely because those ~150 words are used to add value – perhaps sharing an insight or relevant case – versus a one-liner that says “Can we talk?” with no context. Prospects respond when they see what’s in it for them. Emails that fail to articulate a pain point and solution, or at least spark curiosity, won’t earn a reply. And if your email reads like a generic sales brochure or is filled with jargon, it won’t resonate. In 2025, buyers expect outreach to be helpful and human. Many cold emails fail by either being too superficial (no real meat or value offered) or too self-serving (pitching features without relevance). Striking the right balance is critical.

8. Signals of Automation or AI “Tone”

This is a newer factor emerging in 2025. With the rise of AI writing tools, prospects are now receiving a lot of “robotic” sounding emails. Inboxes are flooded with AI-generated noise (5) – templated messages that lack a genuine human voice. Buyers have grown more skeptical and can tell when an email is just a mail-merge template blasted to thousands. If your cold email introduction is clunky or has unnatural phrasing (a sign of a generic AI template), recipients tune out. The irony is we at Martal love using AI to help draft and research – but it must be edited to sound authentic. Over-automation can also hurt deliverability (e.g., sending 10,000 emails at once from a new address screams “spam”). In short, the successful 5% of cold emails feel personal, crafted, and conversation-like, whereas the failing 95% often have the hallmarks of automation. In 2025, humanizing your emails is more important than ever to avoid the fate of being ignored.

These are the primary reasons so many cold emails miss the mark. It’s usually not just one issue, but a combination – e.g. a poorly targeted list + a bland template + no follow-up = low results. The silver lining is that each of these failure points can be flipped into a success strategy. We’ve seen that when companies address deliverability, personalization, targeting, and persistence, their cold email metrics shoot above industry benchmarks.

Now that we know the pitfalls, let’s focus on the solutions. How can you ensure your cold emails are in the winning 5%? The next section breaks down exactly that.

How to Join the Successful 5%: Cold Email Strategies for 2025 Success

By now it’s clear – succeeding with cold email in 2025 means working smarter and harder. The days of spray-and-pray are over. However, the upside to all these challenges is that if you do implement best practices, you can dramatically outperform competitors who don’t. Companies that excel at email outreach generate 50% more sales-ready leads while cutting costs by one-third (1). And email is still one of the highest ROI channels – up to $42 earned for every $1 spent when highly targeted (1). So what are the winning email outreach strategies to get there? Here are actionable ways to boost your cold email performance above benchmark rates:

1. Master Email Deliverability: Tip: Aim for 95%+ deliverability (meaning 95 out of 100 emails land in inbox, not spam). This is foundational – if your emails don’t reach people, nothing else matters. To achieve this:

• Authenticate Your Sending Domain: Set up SPF, DKIM, and DMARC records for your email domain. These technical steps verify you as a legitimate sender. They’ve gone from “nice-to-have” to mandatory for successful email campaigns (1). Lack of proper authentication is a leading cause of cold emails landing in spam.
  
• “Warm Up” Your Sender Reputation: If you’re starting a new email account or sending at high volume, don’t go zero to 100 overnight. Gradually increase sending volume and consider using email warming tools that send low-volume, interactive emails to build a positive reputation. Consistency is key – sporadic big blasts raise red flags.
  
• Use Quality Data & Clean Your List: High bounce rates will crush your reputation. Use email list cleaning services and verify your list to remove invalid addresses. Continuously purge hard bounces and opt-outs. Keeping bounce rate under 3-5% is important (1) (4).
  
• Monitor Engagement Signals: ISPs (like Gmail) look at engagement. If your emails get opened and replied to, you’ll land in inboxes more. If they get ignored or deleted en masse, you’ll slide into spam. It’s a vicious cycle: low engagement → spam folder → even lower engagement. To counteract this, track your metrics by campaign. If you see an extremely low open rate on a send, something’s wrong (could be content or technical). One interesting stat: if your open rates fall below industry benchmarks for long, email providers may algorithmically start filtering you (1) (1). That’s why you should strive to keep subject lines and targeting sharp to maintain decent open rates. It’s all interconnected.
  
• Avoid Spam Triggers: Both in content and sending behavior. Don’t use all-caps or multiple “!!!” in your subject. Don’t stuff the email with links or images with little text. Certain phrases (“100% free”, “act now”) can trip filters (1) (1). And obviously, never buy a list and blast it – that can tank a domain’s reputation overnight. It may be worth using a dedicated sending domain or subdomain for cold outreach, separate from your main company domain, to protect your primary domain’s health.

By getting deliverability right, you set the stage for improved performance across the board. For example, one study noted that improving email deliverability can increase your lead volume by 50% and reduce marketing costs by 33% (1). In short: deliverability is a make-or-break factor – treat it with the same importance as your sales message itself.

2. Craft Irresistible Subject Lines: Given how critical the subject line is for opens, invest time here. Aim for a subject that is personalized, concise, and curiosity-provoking (without being clickbait). Some best practices backed by stats:

• Include the Prospect’s Name or Company: Emails with the recipient’s first name in the subject see higher open rates – one source measured an average 43.4% reply rate when the name was included (4). Even if that stat sounds high, the direction is clear: personalizing the subject gets more attention. For B2B, using the company name can also boost opens by ~22% (4).
  
• Leverage Numbers or Specifics: Subjects with numbers (e.g., “Increase X by 37%” or “3 ideas for [Company]”) can stand out. Numbers convey tangible value. According to research, using numbers in subject lines increased open rates by 113% on average (4). Clearly, specificity beats generic lines.
  
• Ask a Question (When Appropriate): A question in the subject (e.g., “Struggling with [Problem]?”) can create intrigue. This approach has shown to lift open rates by ~21% (4). Just ensure it’s a relevant question to the prospect’s situation.
  
• Keep It Reasonably Short (or at Optimal Length): There’s some nuance here. Very short one-word subjects can come off as vague or spammy, whereas very long ones get truncated. Data from an outreach study indicated subject lines ~36-50 characters achieved the best response rates (3) – likely because they provide enough context. Aim for under 8-10 words generally.
  
• Avoid Spammy Words/Phrases: As mentioned, certain words tank open rates or send you to spam. Steer clear of “Free, Urgent, Act Now, $$, Guaranteed,” etc., in subjects. Instead of “Free consultation”, you might say “Complimentary consultation” – same meaning, less trigger-prone (1).

Remember: The subject’s job is to earn the open. It doesn’t have to sell your service – just get their attention in an honest way. We often find success with subject lines that hint at a benefit or connection, e.g., “Idea for [CompanyName]” or “Quick question, [FirstName].” Once they open the email, your opening line should then deliver on that subject line’s promise.

3. Personalize Everything (at Scale if Possible): Personalization is your strongest weapon to break out of the 95% failure zone. It shows the recipient you’ve done your homework and genuinely see their situation. Effective personalization goes beyond just {FirstName} tokens. Here’s how to join the elite 5% who get significantly higher replies:

• Research and Segment Your List: Group prospects by industry, role, or specific pain point so you can tailor messages. For example, your email to SaaS CEOs might reference scaling revenue, whereas emails to HR directors mention talent retention – even if you’re selling the same service, the angle changes. Use merge tags to insert relevant info (e.g., “[Company]’s growth” or a recent trigger event like a funding round).
  
• Write Custom Opening Lines: The first sentence of your email should not read like a mass email. Avoid bland intros like “I hope you are doing well” (which ironically 24% of successful outreach do include, but it’s overused) or “My name is X and I’m with Y company.” Instead, try a creative hook: reference something about their business, recent news, or a common connection. Even just one tailored sentence at the start can boost engagement. We’ve seen that in practice and it’s supported by data – multi-point personalization can raise reply rates dramatically (4).
  
• Use the 1-2 Punch: Custom Line + Value Proposition: A good formula: after a quick personalized opener, segue into how you can help solve a challenge specifically relevant to them. This requires understanding the prospect’s industry or role pain points. The email should read like it was written for one person. If you can say, “We recently helped a company similar to yours achieve X result,” that’s golden – it’s both personalized and value-driven.
  
• Don’t Forget to Personalize the Subject Line and Call-to-Action: As noted, subject lines with personal elements perform better. Similarly, a call-to-action (CTA) that feels personal (“Would you be open to a 15-minute chat next week about [specific issue]?”) works better than a generic “Let’s talk.” It shows you want to discuss their needs.
  
• Leverage Technology Wisely: Tools like mail merge and AI can assist with personalization at scale, but use them to augment genuine research, not replace it. For example, an AI tool can suggest a snippet about their company from the news which you can incorporate and tweak in your own voice. The top 5% senders often use custom snippets or dynamic fields to personalize at scale – but they always QA the output for authenticity.

Consider that only a small minority of cold emailers fully personalize every email, yet those who do see 2-3x better reply rates (5). This is a huge competitive advantage if you’re willing to put in the effort. Personalization at scale is challenging, but even templating 80% of the email and customizing 20% can yield much better outcomes than blasting a 100% form letter. Quality trumps quantity: It’s better to send 50 highly personalized emails than 500 generic ones in terms of actual positive replies.

4. Provide Value and Build Credibility: A cold email shouldn’t feel “cold.” The successful ones deliver value in the message itself and build credibility quickly. How can you do this?

• Teach Them Something New: Share a brief insight, statistic, or observation relevant to their business. For example, “I noticed your software team is hiring – did you know 80% of tech firms struggle with onboarding salespeople effectively?(10)” If you have a compelling stat or insight (from an industry report or your company’s data) that relates to them, mention it. This positions you as a knowledgeable resource, not just a sales development representative (SDR).
  
• Use Social Proof: Name-drop a relevant client or result (without breaching confidentiality). E.g., “We helped [Similar Company] increase their B2B email response rate from 3% to 10% in one quarter.” If you can cite a concrete result or ROI, do it – numbers speak. Just ensure it’s something that will resonate with their situation.
  
• Keep it Customer-Centric: Focus on their pain points and benefits to them, rather than a laundry list of your product features. A quick formula: “[Problem] is costing [Company] time/money; our [solution] might help by [brief benefit].” By addressing a need they care about, you hook their interest. Remember, as a prospect, they will respond out of self-interest, not because you’ve impressed them with your credentials.
  
• Call-to-Action – Make it Low-Commitment and Clear: Don’t ask for a big commitment (like a 1-hour demo) in a first cold email. A good CTA might be, “Would you be open to a brief 10-minute call next week to see if this is a fit?” or even simpler, “Interested in learning more?” Make it easy for them to say yes. Alternatively, offer something of value in the CTA: “I can send over a custom report/analysis if you’re interested,” to entice a reply.
  
• Tone Matters: Use a friendly, human tone – like one colleague reaching out to another with a helpful suggestion. Avoid overly formal or stiff language (“Dear Sir or Madam” is a non-starter). But also avoid pushy sales talk or hype (“revolutionary, once-in-a-lifetime opportunity!”). A confident, conversational tone works best.

By delivering value and credibility in your email, you earn the right to ask for a meeting or reply. The prospect should come away thinking, “This person understands my world and might actually help.” When you hit that mark, you’ll see your response rates climb above the 5% norm.

5. Optimize Timing, Frequency, and Channels: We know from earlier that timing and follow-ups are critical. Here’s how to execute on those:

• Best Days/Times: The best time to send cold emails is when prospects are most likely to engage. Studies consistently show Monday and Tuesday as top days for cold email replies (4). Mid-week (Wed/Thu) is decent too. Friday is generally the worst (people winding down), and weekends should usually be avoided (3). As for time of day, late morning to early afternoon tends to work well in B2B. One report noted 1pm as the most effective send time, with 11am a close second (3). Think about when your target persona checks email – often right after they settle in at work, or after lunch breaks.
  
• Follow-Up Strategy: Do not stop at one email. Plan a sequence of at least 3-4 touches over a couple of weeks. For example:
  
  • Email 1: Initial outreach with your personalized pitch.
    
  • Email 2: A gentle follow-up ~2-3 days later, perhaps adding a case study or a different benefit (“Just bumping this to your attention, and by the way we helped XYZ with a similar issue.”).
    
  • Email 3: Another follow-up a week later, maybe sharing a resource (ebook, article) related to their pain point – no pressure, just value.
    
  • Email 4: A “breakup email” after another week or so, politely acknowledging they might be busy, and leaving the door open for future contact.
    
• Data suggests two follow-up emails is the ideal minimum for optimal results in B2B outreach (9), and more follow-ups (5+) are often needed to catch busy business leads and improve outbound lead generation (9). In fact, follow-ups can increase reply rates by 50% or more (1). The key is to follow up with professionalism and new info – never guilt-trip the prospect (e.g., avoid “I never heard back from you…” which can reduce meeting booking rates (4)). Instead, maintain a helpful tone. Many prospects thank sales executives on follow-up #3 or #4, saying they had missed the earlier emails. Persistence pays, as long as you aren’t spamming them daily.
  
• Multi-Channel “Omnichannel” Approach: In 2025, the cold email that succeeds is often not just an email. The best campaigns use multiple touches across different channels, such as LinkedIn and phone, to support the email outreach. For example, you might send an email, then a few days later send a LinkedIn connection request or message referencing the email, and even follow up with a brief phone call or voicemail the following week. Research shows LinkedIn InMail messages can have response rates in the 18-25% range (13)– much higher than email alone. By combining channels, you increase overall contact rate. A prospect might ignore your email but notice your LinkedIn profile view and message, which warms them up to go back and read the email. At Martal, our omnichannel marketing strategy is a core part of achieving better-than-average results – we’ve found that integrating email with LinkedIn outreach and even targeted phone calls lifts conversion rates significantly. (We’ll mention more on this in the conclusion.) The bottom line: don’t rely on email alone if you can help it. Cold calling or social selling used alongside email can boost your success far beyond that 5% reply benchmark.
  
• Respect Opt-Outs and Email Cadence: Make sure every cold email sequence includes an easy way to opt out (both legally per CAN-SPAM/GDPR and as a courtesy). If someone hasn’t engaged after 4+ touches, it’s usually wise to pause or put them on a longer-term nurture track rather than blasting indefinitely. Burning bridges with prospects by over-emailing can hurt your brand and domain. Quality outreach balances persistence with respect.

6. Test, Track, and Iterate Continually: The final piece of joining the top performers is a data-driven mindset. Treat your cold email campaigns as experiments that can be optimized. Use the benchmarks we discussed as baselines, but measure your own metrics closely:

• A/B Test Key Elements: Try two different subject lines on small portions of your list to see which yields higher opens. Test different call-to-action wordings, or short vs. slightly longer email body versions. Over time, you’ll gather insights on what resonates with your audience.
  
• Track Engagement by Segment: Don’t just look at aggregate response rate. Break it down by industry, persona, sequence step, etc. Perhaps you find your open rate with tech companies is 30% but with finance industry is 15% – that tells you to adjust messaging by segment. Or you might see that Email #2 in your sequence is getting the most replies – meaning your follow-up content is compelling, and you could consider moving some of that content earlier.
  
• Learn from Any Positive or Negative Outliers: If a particular email got an unusually high reply rate, analyze why. Was it the personalization? The offer? If one got lots of negative responses or unsubscribes, what turned people off? Continually refine your approach. The great thing about cold email is the feedback loop is fast – within a day or two of a send, you have data to learn from.
  
• Keep Up with Trends: The email landscape changes. For example, Apple’s Mail Privacy Protection inflated open rates for Apple Mail users – as a result, some companies now focus more on click or reply metrics as true engagement. Stay updated on deliverability news (e.g., any major ISP rule changes) and buyer behavior trends (e.g., many buyers now read email on mobile – currently over 81% of emails are opened on mobile devices (1) – so make sure your formatting is mobile-friendly with concise paragraphs and possibly bold highlights for key phrases).
  
• Benchmark Against Yourself Over Time: Ultimately, the goal is continuous improvement. If last quarter your cold email reply rate was 3%, aim for 5% this quarter through better targeting and personalization. Then aim for 8%. We have clients who initially struggled at 1-2% reply rates and, through systematic improvements, achieved 10%+ consistently – blowing past industry averages. It’s absolutely possible with diligence and creativity.

By implementing these email marketing and lead generation strategies, you can realistically double or triple your cold email performance relative to the average campaign. Instead of 1-5% reply rates, you could see 10-15%. Instead of a 0.2% conversion rate, you might close 1% of your cold outreach leads – which in many B2B contexts is a huge revenue generator.

One more pro-tip: Don’t hesitate to try multi-threaded outreach to an account. If one contact at a target company doesn’t respond, consider reaching out to another stakeholder there. Studies show that emailing multiple contacts at the same company can increase response rates by 93% compared to single-contact outreach (7). Just ensure you coordinate your messaging and don’t spam everyone at once. A thoughtful approach here can get you into that account via a different door.

Armed with these strategies, you’ll be well on your way to outperforming the benchmarks we discussed earlier. It’s not easy – it requires a shift from thinking of cold email as pure volume to treating it as a precision, omni-channel campaign. But when done right, even in 2025’s challenging environment, cold email is still effective. The next FAQ section addresses some common questions you might have about cold email success rates and tactics.
