About Callbox

Callbox started in 2004 first as a B2B inbound call center but quickly branched out into B2B outbound call services by the next year. Callbox relies on an in-house database for B2B leads that is curated and managed by their research team. These leads are used in database services, outbound outreach, account-based marketing, and promoting live and virtual events.

Callbox has a diverse workforce with offices in the UK, Australia, New Zealand, Hong Kong, Singapore, Malaysia, and the US. However, Callbox’s core team members that handle business development, campaign content, and prospect outreach for clients are located in the Philippines.

Customer Feedback


While Callbox has been around for many years, their reviews are limited on trusted, unbias sites. For example, on G2 there are three reviews for Callbox with a 2.5 out of 5 rating. On Clutch, Callbox has a better rating averaging 4.6 out of 5 with a total of 46 reviews. Given this information based on client feedback, it is hard to determine whether Callbox is a reliable resource for B2B lead generation.


Martal Group has well-documented reviews of our clients’ success on both G2 and Clutch as well as client case studies that can be found on our website. By reading the reviews on these B2B buying guide platforms you’ll see that many of our past and current clients chose Martal because of our expertise in the tech industry, our ability to ramp up quickly, and of course, a high volume of sales qualified leads that can be hard to replicate internally.

Database Optimization


Due to the fact that CallBox uses an in-house database, it is hard to tell whether the prospects’ information is comparable to well-established systems widely used by other B2B lead generation firms. Manual scrapping of data can leaves holes in important information necessary for precision targeting and personalization.


At Martal Group, the success of your campaign is our top priority. Since that success is heavily reliant on access to well-vetted prospect data, we invest in robust databases that incorporate artificial intelligence along with second and third-party cookie data to track the intent of key accounts and decision-makers. In other words, by using the right data we speed up the sales cycle, increase conversions, and make it easier to create a lasting connection.

Team Structure


It’s important to consider the location of your outsourced team before launching a B2B lead generation strategy. At Callbox, the team members that handle direct outreach to key decision-makers are from the Philippines. If you are targeting accounts within the US, having an offshore team can make connecting with upper management and c-level executives difficult. Any hiccups in communication through copy or calls can make it hard to build up trust in your brand and rapport with the individuals.


Because of this, Martal Group is comprised of North American sales executives with years of experience building relationships with US-based B2B prospects in various industries. Our sales team understands that communication styles and pain points vary depending on the prospect’s role and responsibilities. We take that into account when building out your unique campaigns for different verticals.
