How you pay: Apollo’s licences and credits against ZoomInfo’s quotes
ZoomInfo’s pricing page shows plans (ZoomInfo Professional, Copilot Advanced, Copilot Enterprise) without a single amount; its FAQ says the price depends on features, number of licences and credits. Without a published price, there is no price line below: only how each one bills.

ZoomInfo also sells data without its app through GTM.AI (API, MCP, command line), priced per credit from $0.45 down to $0.25 per record, without mobile numbers: a different product from Apollo’s plans, so it is not compared here. Prices seen on third-party sites are not used.
Phone numbers and coverage outside the US
At Apollo, a mobile or direct number costs 8 credits and is never refunded. Its reviews often say numbers are less reliable outside the United States, in Europe especially. Apollo publishes no European coverage figure.
ZoomInfo publishes some: 66M+ contacts, 20.5M+ companies and 18.5M+ mobile numbers in Europe, and says it added 1.8 million mobiles in the UK, France, Germany, Italy, Spain and the Netherlands in 2025. On its data page, it claims to find a mobile for 87% of contacts and a direct line for 72%. These are ZoomInfo’s own figures.
The useful test for a European team is the same with both: a sample of your own market during the trial. Apollo’s trial includes 20 phone numbers.

G2 blocks automated checks: Apollo shows 4.7/5 on its site, and search results show 4.5/5 for ZoomInfo; neither could be verified on G2.
Easier to buy or a bigger database: the trade-off by team size and budget
Taken together, these differences make Apollo easier to buy for a small team, or for one that wants to try before committing: a free plan, a 14-day trial, public prices from $65 per licence a month, monthly billing on Basic and Professional. ZoomInfo publishes no subscription price; its trial typically lasts 7 days and its contracts run 1 to 3 years.
ZoomInfo claims the larger database: 500M+ contacts and 100M+ companies against Apollo’s 240M and 30M, with 66M+ contacts and 18.5M+ mobile numbers in Europe. It is also the older and larger company: founded in 2007 as DiscoverOrg, listed on the Nasdaq (GTM), 35,000+ customers. These are claims from each vendor; neither database can be audited from outside.
Contract terms: renewal, notice and refunds
Apollo.io
Monthly or yearly, paid upfront. To stop, Apollo’s FAQ points to a cancellation in the app that takes effect when the billing cycle ends, while its terms ask for written notice no later than 30 days before renewal. Removing licences is just as unclear: immediate and unrefunded per the FAQ, not allowed during the term per the terms. The terms (August 10, 2026) say fees are non-refundable; they fall under Californian law, with arbitration.
ZoomInfo
Its public terms (May 1, 2025) describe a contract that cannot be cancelled during its term, with a refund only when ZoomInfo fails its own commitments (an uncured breach after 21 days, availability under 99.9% twice in three months, or more than 5% of contacts wrong and not fixed within 30 days). Shared logins are billed as extra licences until the end of the term.
Renewal is now set by each order form. The March 6, 2024 version of the terms renewed contracts automatically unless notice was given 60 days before the end, at a price 10% higher; that clause was removed in 2025. For a European customer, the contract falls under the law of England and Wales.
What neither one does: automate LinkedIn
Apollo turns LinkedIn steps into manual tasks; ZoomInfo’s extension reveals contact details on a profile and its plans use LinkedIn only for ads. Both leave connection requests and messages to the salesperson.
Emelia automates them in the same sequence as emails, with unlimited actions: 1 LinkedIn account on Start (€37 a month), 3 on Grow, 10 on Scale. It has no database: it finds and verifies emails on the lists you export from Apollo, ZoomInfo or elsewhere.
Apollo or ZoomInfo: the right pick by team and region
Pick Apollo
If you are a small or mid-size team, want to see the price before talking to sales, or prefer to pay by the month. Phone numbers at 8 credits and a dialer suit teams that call the US.
Pick ZoomInfo
If you need the coverage it claims, in Europe in particular, can commit to a contract of one to three years and want the vendor to carry data-quality commitments in writing. Ask for the order form’s renewal clause before signing.
Add Emelia to either
If your team prospects on LinkedIn as much as by email: neither database automates it.
Apollo vs ZoomInfo: the questions buyers ask
Apollo publishes it: 2 Professional licences cost $198 a month ($158 billed yearly), 3 licences $297. ZoomInfo quotes each team and publishes no price, so no fair figure can be put against it.
Not without paying for both: ZoomInfo’s terms describe a contract that cannot be cancelled during its term, outside ZoomInfo’s own breaches. Apollo can be started on a free plan or a monthly plan alongside it until the renewal date.
Only the vendors’ claims are public: ZoomInfo announces 18.5M+ mobile numbers in Europe; Apollo publishes no European figure, and its reviews report weaker phone data outside the US. Test both on your own market: Apollo’s trial includes 20 numbers, ZoomInfo’s typically lasts 7 days.
Emelia is an Apollo.io competitor. We have tried to stay fair: every figure about Apollo.io comes from its own website or public review sites.
