Apollo vs ZoomInfo: Data

Buyers frequently compare how many email addresses and direct phone numbers ZoomInfo and have. So, let’s look at those numbers.

  • The ZoomInfo contact database is said to have 220 million active contacts, over 150 million email addresses and 50 million direct dials in its contact database. 
  • In comparison, has over 265 million contacts at over 70 million companies, 165 million email addresses and 120 million phone numbers (according to’s homepage).

Both ZoomInfo and Apollo are based in the US, and according to Klue, a market intelligence platform, this is where their data coverage is the best.

According to T&Cs, its extensive database includes user-submitted data. So, by using Apollo, customers agree to give Apollo an irrevocable license to use their data, even after they stop using Apollo’s software. So even if you’re signing up for their free plan, you’re adding to their database.

On the other hand, ZoomInfo has built its platform by acquiring competitors. In recent years, their focus seems to have shifted from being a prospecting data provider to a sales workflow management solution.

Which is more accurate, ZoomInfo or

Despite their best efforts, no data provider is 100% correct in all areas. A recent survey of Pavilion members who recently evaluated ZoomInfo vs Apollo’s data quality revealed areas where both providers could improve.

ZoomInfo vs Apollo cost

The main difference between and ZoomInfo’s pricing?

Apollo pricing offers monthly and yearly subscriptions and a self-service signup flow. In contrast, ZoomInfo offers long-term contracts, and its pricing is available after a consultation. 

For this reason, is generally considered to be cheaper than ZoomInfo and other sales prospecting tools.

Despite these differences, Apollo’s and ZoomInfo’s prices are based on a credit system that limits viewing and exporting data. Monthly caps, resets, and expensive ‘add-ons’ often pose some challenges:

  • Scarcity mindset among your team — reps are more focused on optimising credit consumption than developing best practices for prospecting.
  • Unpredictable spend — e.g. ZoomInfo charges a credit for every company and contact export which may consume double the credits if the account isn’t already in their CRM. Similarly, Apollo charges one credit for email and another credit for a phone number. reviews on G2 complain about the low credits and high costs.
  • Limited opportunities - companies with an international presence or trying to expand to new markets may find the price for ZoomInfo’s Data Passport for prospecting outside the US hard to justify.
  • Slow growth — despite relatively cheap plans, Apollo offers very limited access to mobile and export credit (max. 125 and 2000, respectively in its highest plan). It may become problematic for businesses with ambitious growth goals or companies in highly competitive markets.

ZoomInfo is CCPA and GDPR-compliant. The provider also checks do-not-call lists in Australia, Canada, France, Germany, Ireland, New Zealand, the UK, and the US. is CCPA compliant and also claims it’s compliant with GDPR. Apollo has recently started offering DNC list cleaning in the UK & US only. The provider charges one credit if a phone revealed is on a DNC list and claims it is then at the users’ discretion to decide if they call or not.

Why is DNC list cleaning important?

If a salesperson reaches out to someone who has opted out of sales and marketing phone calls, they may be accused of not having “a legitimate interest” in contacting that person.

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.

How do customers evaluate the providers?

“Firstly, we trialled Apollo using a test data sample which didn’t produce adequate results.

"We proceeded to evaluate ZoomInfo but found the data to be too US-centric. This didn’t fit our ICP of targeting UK companies.” 

Cognism is essential to our tech stack and for influencing our deals. The superb data quality has instilled a unique level of confidence in the SDRs.“

 Marc Parsons, SDR Team Lead at OneUp Sales

“Our legal team reviewed ZoomInfo’s GDPR standards in Europe, and they were not up to scratch. As a result, they removed the European team’s access to the platform, which massively impacted our sales output."

"A core reason for unlocking the Cognism conversation was for its compliant reputation."

Pierre Bourguignon, SDR Manager at Cloudreach
