Apollo vs ZoomInfo: Which B2B Data Platform Should You Buy in 2026?

Apollo is the better choice for startups, agencies and small to mid-size sales teams: it bundles a large B2B database with sequences, a dialer and CRM sync at published per-seat prices, and you can start free. ZoomInfo is the better choice for enterprise teams that need deeper company intelligence, intent data, compliance paperwork and a dedicated account team, and that can commit to an annual contract.

Apollo vs ZoomInfo at a glance

Pricing: published plans vs annual contracts

Pricing is the biggest difference between the two, and for most small teams it decides the question.

Apollo pricing

Apollo's pricing page lists Free, Basic, Professional and Custom plans and explains that credits are pooled across the team, granted at the start of each billing cycle, and do not roll over. The page itself does not show dollar figures in its text, so the numbers below come from 2026 third-party pricing reviews.

Valley (October 2026) and Saleshandy (September 2026) also list an Organization plan at about $119 per user per month with a three-seat minimum. Confirm current figures on Apollo's pricing page before you buy.

The cost to watch on Apollo is credits. According to Apollo's help center and 2026 pricing reviews, an email reveal costs 1 credit and a phone number costs 8. A team that mostly emails gets a lot from its allowance; a team that mostly calls will need to buy more credits.

ZoomInfo pricing

ZoomInfo does not publish prices. Its pricing page says pricing depends on licenses, credit usage and features, and that "our sales team will work with you on payment frequency and options."

The best public picture comes from third parties. Saleshandy, which sells a competing product, reported in October 2026:

• One list-price quote from a ZoomInfo SDR: $5,000 for one seat, $10,000 for Professional with three seats, $15,000 for Copilot Advanced with three seats and $21,000 for Copilot Enterprise with five seats. Saleshandy noted these were "standard listed prices and not the final negotiated rates."
• Third-party reported ranges: Professional about $15,000 to $18,000 a year, Advanced about $22,000 to $29,995, and Enterprise $35,995 to $45,000 or more.
• Add-ons outside the base price, including Global Data Passport (about $4,500 a year per Saleshandy).
• Reviewer reports of annual or multi-year terms, 60 to 90 day cancellation notice windows and renewal increases of 10% to 20%.

Treat these as rough guides, not quotes. The point stands either way: ZoomInfo is a five-figure annual commitment for most teams, while Apollo can be bought by one person with a credit card.

Pricing winner: Apollo, clearly, for any team without an enterprise data budget.

Data coverage and accuracy

Both vendors make strong claims, and neither publishes an independent audit.

Apollo says on its homepage that it has 240M+ contacts and 30M+ accounts. Its help center describes sources including a contributor network, engagement data such as replies and bounces, public web crawling and third-party providers, with "monthly checks across the full database." Apollo says its verified emails have an accuracy rate of 91% and refunds the email credit if a verified email bounces within 30 days.

ZoomInfo says it has verified data on 500M+ contacts and 100M+ companies, and that 300+ human researchers verify records. It also offers Data as a Service for teams that want ZoomInfo data piped into their own systems.

On paper, ZoomInfo has the bigger and more researched database, and it has a long reputation for depth on large companies and org charts. In practice, the right answer depends on your market. A provider that is excellent on US enterprise software can be thin on mid-size manufacturers in the Midwest or small agencies in Europe.

The only fair test is your own: pull a sample of 100 to 200 target contacts from each tool, verify the emails, and check titles against LinkedIn. Apollo's free plan makes its side of the test cheap, and ZoomInfo's free trial can cover the other.

Data winner: ZoomInfo on claimed depth and enterprise coverage. Apollo is competitive for most SMB and mid-market targets at a fraction of the cost.

Prospecting features

Search and filters

Both tools let you filter by title, seniority, industry, company size, location and technology. Apollo's help center says it offers 65+ search filters. ZoomInfo's pricing page lists contact and company profiles, search and export, and account prioritization and alerts on Copilot Advanced.

Chrome extension

Both have one. Apollo's extension works on LinkedIn, Gmail, Google Calendar, Salesforce, HubSpot and company websites, and can add contacts directly to Apollo, Outreach or Salesloft sequences. ZoomInfo lists a Chrome extension on its Professional tier.

Intent and signals

This is where ZoomInfo pulls ahead. Its Copilot Advanced tier adds buyer intent signals, website visitor data and champion tracking, and Copilot Enterprise adds real-time buyer intent and AI-generated account summaries. ZoomInfo's marketing packages go further, with up to unlimited intent topics on ABM Enterprise.

Apollo has intent topics and signals too (its free plan includes one intent topic, per 2026 reviews), and its AI Assistant, launched in March 2026, can research accounts and build lists. For teams that run account-based plays on intent data, ZoomInfo's depth is the stronger offer.

Prospecting winner: ZoomInfo for intent-driven enterprise selling; Apollo for fast list building at SMB budgets.

Outreach: sequences, dialer and deliverability

This is Apollo's home turf.

Apollo was built to go from search to send in one place. You build a list, add it to a multi-step sequence with emails, calls and LinkedIn tasks, and track replies and meetings in the same workspace. Its dialer charges credits by the minute (1 credit per 30 seconds on US calls, per Apollo's help center and 2026 reviews), and unanswered calls use no credits.

Apollo also includes deliverability tooling that many data providers lack. Its help center describes buying domains and mailboxes inside Apollo, automatic SPF, DKIM and DMARC setup for those domains, warmup, blocklist checks and inbox placement tests. Its sending guidance starts each mailbox at 50 emails a day.

ZoomInfo lists "sales automation" for phone and email outreach, plus AI email generation and workflows on its Copilot tiers. Its public pages do not detail sequence limits or which package includes which outreach features, so ask your rep exactly what you get.

For high-volume cold email, neither tool is the ideal sender. Many teams keep Apollo or ZoomInfo as the data source and send from a dedicated platform such as Smartlead or Instantly, which are built around many mailboxes and warmup. Our Apollo to Smartlead workflow shows how that handoff works.

Outreach winner: Apollo.

Integrations and API

Apollo integrates with HubSpot (two-way sync of contacts, accounts and deals), Salesforce, Pipedrive, Outreach and Salesloft, and lists 200+ integrations on its homepage. One limitation: Apollo connects to only one CRM at a time. Its API has published rate limits by plan.

ZoomInfo lists CRM integrations on every Copilot tier, custom integrations on Copilot Enterprise, and Data as a Service for warehouse-level delivery. Saleshandy reports that pre-packaged integrations may require a minimum bulk-credit purchase.

Integrations winner: ZoomInfo for complex enterprise stacks; Apollo for standard CRM setups.

Support, onboarding and compliance

ZoomInfo's Copilot Enterprise includes a dedicated customer service manager and white-glove onboarding, and its homepage lists ISO 27001, ISO 27701, SOC 2 Type II and TRUSTe certifications plus GDPR and CCPA compliance. For a procurement or legal team, that list matters.

Apollo's lower plans are largely self-serve, and its Custom plan adds SSO, advanced security and dedicated support. Capterra reviewers have raised slow support as a complaint. If you want hands-on help with Apollo without an enterprise contract, a certified partner can set it up for you.

Support winner: ZoomInfo.

Head-to-head scorecard

Who should choose Apollo

• Founders and small sales teams who want to build lists and send sequences without buying several tools.
• Agencies running outbound for clients across many industries. Apollo's per-seat pricing scales with headcount, not a large upfront contract.
• Mid-market teams that want data, sequences and a dialer in one tool, and that would rather spend the difference on reps or sending infrastructure.

Our Apollo.io review covers plans, credits and setup in detail, and our guide on how to use Apollo for prospecting walks through building your first list. When you are ready, start on Apollo's free plan.

Who should choose ZoomInfo

• Enterprise sales and marketing teams that run account-based programs on intent data.
• Organizations with strict procurement that need security certifications and a dedicated account team.
• RevOps teams that want data delivered into a warehouse or across a complex stack.

If that is you, ZoomInfo's depth can justify the contract. Negotiate seat counts, credits and renewal terms carefully, and get the renewal price in writing.

Rather not run it yourself?

Picking the data tool is step one; building lists, writing sequences and keeping your domains out of spam is the ongoing work. Koldify is a done-for-you cold email agency that runs campaigns on PlusVibe, Smartlead and Email Bison. If you would rather hand it off, book a 30-minute call with David at Koldify.

The verdict

For most teams searching "Apollo vs ZoomInfo," Apollo is the right buy. It gives you a large database, sequences, a dialer and deliverability tools at a published price, and a free plan to prove the data works for your market before you pay.

ZoomInfo wins when you are an enterprise team that needs deeper intelligence, intent data, compliance credentials and a dedicated success manager, and when the budget for a five-figure annual contract is already there. If you are not sure which camp you are in, test Apollo free on a sample of your target accounts first. For a wider view of the market, see our roundup of the best B2B data providers.
