The main differentiator between Cognism and Apollo is the availability of cell phone numbers in their packages. 

Cognism doesn’t limit users’ access to mobile data, whereas Apollo caps mobile credits in every plan. Apollo offers only 125 mobile credits/month in its highest Organizational plan.

Apollo has a 7-step email verification process, while Cognism uses 16 steps to verify emails. Apollo mentions verification via data contributor networks, public data crawling, and third-party data providers. 

At Cognism, the process includes proprietary technology, third-party data providers, publicly available sources, manual research and strategic partnerships.

Apollo’s looser email verification process may produce more email addresses than Cognism. But we recommend testing a data sample from both providers to check their accuracy.

Where does Apollo gather its data?

Apollo openly admits to ”scraping from hundreds and millions of websites”. On top of that, they “use machine learning algorithms and utilize a proprietary data network of contributors”.

According to’s T&Cs, Apollo’s customers grant Apollo a “perpetual and irrevocable licence” to access and use, share, sublicense, display, copy, publish and distribute any customer-submitted data. 

This means that by connecting your CRM to Apollo’s software and using its services, you’re adding data to their database.

In contrast, at Cognism, your customer data stays with you.

Compliance status

Cognism’s compliance status is straightforward—we’re CCPA and GDPR compliant. 

Cognism collects only B2B emails and notifies its database. And you can hide contacts that are on do not call lists, giving you complete confidence in the legality of your outreach.

If you’re comparing Cognism vs, you should know Cognism checks all mobile numbers against: 

  • TPS/CTPS lists in the UK.
  • Do-Not-Call lists in the USA, Canada, Australia and European countries, including Germany, France, Spain, Ireland, Belgium, Croatia, Portugal and Sweden.
  • If a number is marked as TPS or DNC, it means that the user has opted out from receiving unsolicited phone calls by applying to the national do-not-call registry.

Apollo claims CCPA and GDPR compliance. The vendor has recently started checking DNC lists in the UK & US (the feature is in Beta). vs Cognism checking lists in 12 countries.

Another difference between and Cognism is that Apollo Apollo charges a credit if a phone revealed is on a DNC list, claiming it is at the users' discretion to decide if they use it or not. On the other hand, Cognism's licence model ensures you don't waste credits on DNC numbers.

Why is DNC cleaning important?

The Information Commissioners’ Office (ICO) has issued fines totalling £180,000 for two companies that made more than 480,000 unlawful marketing calls to businesses signed up with the UK’s “Do not call” register.

Partnering with a fully-GDPR compliant data vendor was a key requirement in the vetting process. From the get go, our Managing Director was far more confident with Cognism because of its compliant reputation and ISO 27701 accreditation.

On the other hand, Apollo’s pricing includes three paid plans that are set per user, per month: $39, $79, and $99.

Apollo’s plans have unlimited emails and a set number of credits for accessing mobile numbers (max. 125) and exporting data (max. 2,000). The higher up your plan, the more advanced features you get, like sequencing.

With, buying an extra 1,000 add-on mobile credits costs $170/mo, and extra 1,000 export credits cost $50/mo. If you’re a heavy dialer, can be more expensive than Cognism.

Is cheaper than Cognism?

Unlike Cognism, Apollo offers monthly subscriptions starting at $49 per user that appeal to companies with tight budgets or companies that don’t want to commit to annual plans. 

However, Apollo’s credit-based system, with very limited access to mobile credits, may lead to unexpected costs.

The sales managers used to make 100-150 calls per day. Now they can achieve their targets by making 30 calls per day because they are calling prospects who actually pick up the phone. That’s more results, less calls.

Cognism and source intent data but from different providers. Cognism partnered with the industry leader Bombora, while Apollo uses LeadSift.

intent data email-1

Unlike LeadSift, Bombora’s intent data isn’t scraped. It’s consent-based and collected from a cooperative of 5,000 B2B sites, where B2B buyers actively research a topic when they’re ready to make a purchase. 

  • It considers the historical baseline or typical content consumption when calculating intent.
  • It considers the context and the length of each interaction.
  • Bombora’s dataset is 70% exclusive.

Combining Bombora’s buyer intent with Cognism’s contact data, you can find, prioritise, and connect the right prospects at the right time. It shortens the sales cycle, improves targeting, and creates a more relevant buyer journey. 

I generate the data in the WebApp on behalf of the BDMs using the staffing and RPO intent topics. In the search, I can see what topics are surging alongside the surge number. Once I've refined the contacts according to their surge number, I sync the lists into our Bullhorn CRM and assign the contacts from each vertical to an individual BDM. The BDM will then contact the desired prospects within the surging accounts with a personalised message.
