Apollo vs ZoomInfo for B2B Data: Price, Coverage and Which One to Pick in 2026

Apollo vs ZoomInfo at a glance

When I plan outbound for a B2B team, I map out the companies first, then move to people. The data vendor decides how good both lists can get. Neither vendor pays me, and there are no affiliate links in this article.

What each costs (checked 14 October 2026)

Apollo: published, per seat, paid in credits

An email costs 1 credit and a phone number 8. So a Basic seat on monthly billing, $65 for 2,500 credits, works out at about 2.6 cents per email found, or about 21 cents per phone number. Credits are pooled across the team, don't roll over and every seat on an account has to be on the same plan. I cover Apollo's dialer add-on and GDPR settings in Apollo vs Cognism.

ZoomInfo sales plans: quote only

ZoomInfo's pricing page lists three sales plans (Professional, Copilot Advanced and Copilot Enterprise) and no prices. Its FAQ says the price depends on features, licenses and credit usage. Each exported contact or company profile costs one credit, your package comes with a set number of credits a month and integrations add a base cost plus a minimum purchase of bulk credits.

For a reference point, Vendr, which helps companies buy software, says the median ZoomInfo buyer pays $33,500 a year, based on 1,576 purchases, with a range from $7,233 to $156,053 (page last updated February 2026). That's what other companies paid, not a quote for you. I explain how ZoomInfo's Records Under Management changes the math in Clay vs ZoomInfo.

ZoomInfo's free start: GTM AI

The biggest change in 2026 is that ZoomInfo now also sells its data by the record. GTM AI, built by ZoomInfo, is headless: you reach its contact, company and intent data through an API, an MCP server or a command line tool, so an AI agent or your own scripts can query it. From its pricing page today:

• 1,000 data credits and 1,000 AI credits free at signup, no credit card.
• After that, pay as you go from $20, with no contract and no seat fees.
• One data credit enriches or exports one company, contact or intent record: $0.38 each at the $1,000 spend tier, with 70% off your first data credit purchase for a limited time. AI credits, for research and agent work, are $0.05 each.
• Search, lookup and "find similar" use no credits.
• Mobile phone data and a waterfall across 25+ vendors are listed under Enterprise packages. Its FAQ says Records Under Management, no re-charge for the same record within 12 months, is an Enterprise benefit and doesn't apply to the free tier.

So ZoomInfo is no longer only for teams with a five-figure budget. But it's a different way in: no mobiles at this level, and you work through an API or an AI agent rather than the search screen your reps would use. It fits a team that already builds lists with code or AI agents. I go deeper on that side in ZoomInfo's GTM.AI CLI: a build vs buy guide.

Per record, Apollo is far cheaper on paper: about 2.6 cents per email on a Basic seat against 38 cents per GTM AI data credit. ZoomInfo says its research team verifies every record before you query it. Only a test on your own market tells you if that's worth about 15 times the price.

Data quality: vendor claims and one outside test

Apollo claims 98% email accuracy. ZoomInfo claims "up to 95% accuracy on first-party data" on its comparison page and "accuracy rates over 95%" on its database page. Neither shows a sample or a method, and ZoomInfo's pages don't agree on its size: 500M, 500M+ or 410M+ contacts depending on the page. Read all of these as marketing numbers.

The only head-to-head numbers I could trace come from Cleanlist, which reports a 1,000-lead benchmark run in March 2026: email match 78% for Apollo and 84% for ZoomInfo, mobile match 41% and 67%. Two caveats. Cleanlist sells its own enrichment service that competes with both, and its post doesn't publish the sample or the method. Take the direction from it, ZoomInfo ahead and furthest ahead on mobiles, not numbers to plan around.

Where your market sits matters more than any total, and neither vendor publishes coverage by country on the pages I checked. That's why the test below matters.

Phones, sending and the rest of the stack

Phones. Apollo charges 8 credits per phone number. Its US dialer costs 1 credit per 30 seconds, and international, power and parallel dialing come in an Advanced Dialer add-on at $119 per team a month billed yearly. ZoomInfo includes mobile numbers and business emails from its Professional plan, with what it calls intelligent dialing. If your reps live on the phone, the mobile gap is the number to test hardest.

Sending. Apollo runs the outreach too, with sequences on every plan and warmup and mailbox buying on paid plans. ZoomInfo is closer to a data layer: Copilot Advanced adds outreach workflows and exports emails to Outreach or Salesloft.

Whichever data you buy, the sending rules don't change. This is how I set it up for clients: separate domains and mailboxes warmed for 3 to 4 weeks, 20 to 30 emails per mailbox per day and email and LinkedIn in one sequence. Apollo's "unlimited daily sends" is a plan limit, not a safe volume. Verify every email before it goes out, whichever vendor found it: see my email verification tools comparison.

How to test both before you sign

1. Pick 100 people you'd really prospect, spread across your actual markets and seniority levels.
2. Run them through both: Apollo's free plan or 14-day trial, and ZoomInfo's 7-day trial. GTM AI's free credits work for emails, but don't expect mobiles there.
3. Count for each vendor: right person at the right company, work emails that pass a separate verifier and mobile numbers found.
4. Work out cost per usable contact: divide what you'd pay each month by the number of contacts you'd get at the pass rate from step 3.

You can also ask the ZoomInfo rep to run step 2 before the demo:

"We're comparing ZoomInfo with Apollo. Before the demo, could you run these 100 named contacts and tell us, for each one, whether you have a verified work email, a mobile and a direct dial? We'll run the same list through Apollo."

Pick Apollo if, pick ZoomInfo if

Pick Apollo if

• You prospect mostly by email and want data and sending in one login.
• You want to start this week on a card, from $0 or $49 a seat, and change plans month to month.
• You're a small team and a five-figure annual contract would eat the budget for everything else.
• Your test shows Apollo covers your market well enough.

Pick ZoomInfo if

• Your reps call and reaching buyers on mobile drives your meetings.
• You sell to larger accounts and want intent signals, website visitors and buying groups (Copilot Advanced and up).
• The budget fits an annual contract, with Vendr's $33,500 median as a rough guide.
• You build lists with code or AI agents and want verified records one at a time through GTM AI.

Running both, Apollo for sequences and emails and ZoomInfo for mobiles and intent on priority accounts, means two bills. Do it only when your test shows ZoomInfo finds enough contacts Apollo misses. To combine sources instead of picking one, Clay vs ZoomInfo shows how ZoomInfo plugs into a Clay waterfall.
