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.
Apollo’s trial includes 20 phone numbers; ZoomInfo’s typically lasts 7 days. Emelia, which has no database, finds the numbers of the contacts you bring through a waterfall across several providers, at 50 credits per number found, refunded when none is found.

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.
Public prices or a larger claimed database: how the two differ
Apollo publishes its prices: a free plan, a 14-day trial, 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.
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. European customers sign their contract with ZoomInfo UK Ltd..
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, and on a LinkedIn profile its Chrome extension finds the person’s email and phone number, then adds them to an Emelia campaign.
Apollo, ZoomInfo and Emelia: what each one is built for
Emelia
LinkedIn and cold email in one sequence, on the lists you export from Apollo, ZoomInfo or elsewhere: neither database automates LinkedIn. Emails are found and verified for 1 credit, phone numbers through a waterfall across several providers for 50 credits, refunded when none is found, and plans start at $37 a month.
Apollo.io
A database with public prices per licence, monthly or yearly billing, a free plan and a 14-day trial; phone numbers at 8 credits and a US dialer paid in credits.
ZoomInfo
The larger coverage it claims, in Europe in particular, sold on quote with contracts of 1 to 3 years and data-quality commitments written into its terms.
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. The contract runs until its end date whatever you add next to it; Apollo, for its part, has a free plan and monthly billing on Basic and Professional.
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. Apollo’s trial includes 20 numbers, ZoomInfo’s typically lasts 7 days. Emelia, without a database, finds the numbers of your own contacts through a waterfall across several providers, and refunds the credits when none is found.
