How much data do Apollo.io and ZoomInfo have?

Both Apollo.io and ZoomInfo have large databases. Apollo has strong data outside the US, with 212M contact profiles. ZoomInfo has strong data in the US but now has 200M contacts outside North America.



Apollo.io checks email addresses with a detailed seven-step process, while cell phone numbers are verified automatically. Users like Apollo.io for its US data, but it’s uncertain how much data they have in specific parts of Europe and APAC. Some reviews on G2 say Apollo.io doesn’t have much data from Eastern Europe or the Middle East.


ZoomInfo has more data than Apollo, with 321 million contacts. There are a few different ways that ZoomInfo gets its data; they are through a contributory network, machine learning on corporate websites and other public sources, human-research teams, and third-party providers. Some users highlight that ZoomInfo’s data deteriorates outside of the US, so this is an important consideration when evaluating these two providers against one another.

Apollo.io vs. ZoomInfo pricing plans

Apollo.io and ZoomInfo both have different pricing structures. Apollo offers monthly or annual plans that are like a subscription you can turn on or off when they expire. ZoomInfo on the other hand, have longer-term contracts tailored to your business’s needs. The pricing for ZoomInfo’s contracts is available after a consultation with a sales professional.


Despite the pricing differences, Apollo and ZoomInfo both run on a credit-based system where your agreement includes a bundle of credits, which you exchange for contact details. If you run out of credits in your plan, you can purchase add-ons for both Apollo and ZoomInfo.


It’s easy to find Apollo’s pricing on their website; they also offer a free plan that includes unlimited email credits, 60 cell phone credits (or 5 per month), and 120 export credits (or 10 per month). ZoomInfo offers a free trial, but unlike Apollo’s, which is free forever, it only lasts 14 days.


Here are Apollo’s pricing plans and the credits included in them:

  • Basic $49 annually or $59 monthly: Unlimited email credits, 900 cell phone credits (or 75 monthly) and 12,000 export credits (or 1,000 monthly).
  • Professional $79 annually or $99 monthly: Unlimited email credits, 1,200 cell phone credits (or 100 monthly) and 24,000 export credits (or 2,000 monthly).
  • Organization $119 annually or $149 monthly: Unlimited email credits, 2,400 cell phone credits (or 200 monthly) and 48,000 export credits (or 4,000 monthly).


Apollo.io updates its pricing fairly regularly (this is correct at the time of writing).


ZoomInfo has a ‘data passport’ if you are prospecting outside the US. The passport is an additional expense, so ZoomInfo may not suit people prospecting in Europe, APAC and EMEA. In summary, on pricing, Apollo vs ZoomInfo is hard to evaluate against one another until you get a consultation and quote for how much a ZoomInfo contract is likely to cost.

Apollo.io vs ZoomInfo: Compliance status

ZoomInfo complies with CCPA and GPDR; they check their data against Do-Not-Call (DNC) lists in Australia, Canada, France, Germany, Ireland, New Zealand, the UK and the US. 


Apollo.io is also fully compliant with GDPR but is only aligned with CCPA. As a new feature, they have also recently started checking against DNC listings when you request a new UK or USA direct dial number. You will see the DNC tag within the Apollo web app if the contact is on a UK or US registry.


What is DNC list cleaning?

A DNC list is a list of contacts scrubbed against your data to ensure you don’t call anyone on it. These people have preferred not to be contacted by unsolicited sales calls. Companies who continue to call people on DNC lists may be at risk of fines. 

Prospect without any worries

Kaspr doesn’t scrub against DNC lists, but we ensure alignment with GDPR and CCPA, allowing you to prospect with peace of mind.


Our database undergoes continuous updates through rigorous verification processes to maintain these standards.


Kaspr’s data comes from:

  • Publicly available information. We get this from information that’s available online, including corporate websites, job postings, news feeds, and company registries.
  • Partnerships with premium data providers. We’ve got carefully selected partners. This helps to make our data super accurate and verified in real-time.
