Apollo.io review 2026: features, pricing, and who it actually fits.
Apollo.io combines a large B2B contact database with sequencing and dialling in one subscription, from a usable free tier up to $99 per user per month. It is a strong fit for small and mid-market outbound teams prospecting into US companies. Two things deserve attention before you commit: credits are consumed even when the data returned is wrong, and Apollo's terms of service combine auto-renewal, a 30-day cancellation notice, and blanket non-refundability.

Credits are the product, and they burn on misses
Apollo's pricing looks like per-seat SaaS and behaves like metered data. The seat price is the smaller half of the decision.
Credits are consumed on enrichment and on every exit from Apollo, which includes CSV export, CRM sync, and pushing records to Outreach or Salesloft. Apollo's own calculator puts email enrichment at 2 credits per record against roughly an 88 percent match rate, and phone numbers at 8 credits per contact against roughly 81 percent. Those match rates are the important part: the shortfall is credits spent on records that return nothing usable.
Reviewers confirm it directly, reporting that "credits are still consumed even when the data returned is incomplete or inaccurate," and that it is "difficult to predict exactly how many credits I will burn through." Credits expire at the end of the billing cycle and do not roll over.
The word unlimited also deserves care. Apollo's fair use policy caps paying accounts at the lesser of dollars paid divided by $0.025, or one million email credits per account per year. Non-paying accounts get 10,000 credits a month with a verified corporate domain, and only 100 without one.
Data quality: strong on US email, weak elsewhere
Business email accuracy is Apollo's genuine strength, and reviewers say so, with one describing emails as "naturally 10/10." The Chrome extension over LinkedIn is the workflow most users cite as actually saving them time.
The weaknesses are specific rather than general. Phone numbers are the weakest data class and cost the most at 8 credits each. International coverage is materially worse than US coverage, reported repeatedly. And data decay is the single most common complaint, with one reviewer quantifying it as "10 to 15 percent of contacts have outdated information, which hurts deliverability" and another noting the data is "somewhat old now compared to a few years back."
Read the terms before you sign, not after
This is the section most reviews skip and most complaints trace back to. It is all in Apollo's published terms of service.
Subscriptions auto-renew unless you give 30 days' written notice. All payments are non-refundable, with no refunds for partially used services. Fees are described as non-cancelable and non-refundable and cannot be decreased during the subscription term. Mid-term downgrades produce no refund, and add-on downgrades only take effect at the end of the cycle while upgrades bill immediately.
Billing disputes in the review record are unusually heated as a result. One G2 reviewer characterised Apollo's billing conduct as extortion, alleging support refused access to unused prepaid credits without further payment. We cannot verify individual accounts, but the terms above are Apollo's own published policy and they explain why these disputes end the way they do.
One more clause worth knowing: standard plans are for internal business use only. Powering an external product or resharing the data requires a separate agreement.
What Apollo.io costs.
Four tiers. The free plan is unusually usable, which is why most teams evaluate Apollo properly before paying.
- Basic engagement tools
- Limited database access
- Gmail-only mailbox connection
- 10,000 credits per month with a verified corporate domain
- Contact access
- CRM integrations
- Email automation
- Advanced automation
- Engagement tracking
- AI insights
- Dedicated support
- Advanced analytics
- API access
- Free trial is 14 days and includes 50 credits plus 5 mobile credits.
- Credits expire at the end of the billing cycle and do not roll over. Annual plans release credits upfront.
- Enrichment costs per Apollo's calculator: email 2 credits per record at roughly 88 percent match, phone 8 credits per contact at roughly 81 percent.
- Export credits are consumed on every exit from Apollo, including CSV, CRM sync, and API enrichment pushed to Outreach or Salesloft.
- API access is restricted to Custom plans. Non-paying plans can only connect Gmail.
What works, and what does not.
- Database breadth and filter depth make it the most efficient prospecting tool many reviewers have used.
- The Chrome extension over LinkedIn is the workflow users most often describe as a real time-saver.
- Business email accuracy is rated high, particularly for US-based contacts.
- Prospecting, sequencing, and dialling in one tool removes the need for a separate engagement vendor.
- The free tier is unusually capable, so evaluation is fast and low-risk.
- CRM sync to Salesforce and HubSpot works well enough that teams treat Apollo as the top-of-funnel layer.
- Data decay is the dominant complaint, with one reviewer quantifying 10 to 15 percent of contacts carrying outdated information.
- Phone numbers are the weakest data class and the most expensive at 8 credits each against roughly an 81 percent match rate.
- Credits are consumed even when the data returned is incomplete or inaccurate, so you pay for misses.
- Credit spend is hard to forecast, with reviewers reporting excessive consumption on email-only exports and forced waterfall verification.
- International coverage is materially worse than US coverage, reported consistently.
- Subscriptions auto-renew and require 30 days' written notice, while all fees are non-refundable and cannot be decreased mid-term.
- Mid-term downgrades produce no refund, and add-on downgrades only take effect at cycle end while upgrades bill immediately.
- Deliverability is inconsistent, with reviewers reporting higher bounce rates than expected.
- Reliability complaints are specific, including needing to refresh repeatedly after spending credits to reveal contact information.
- The interface is described as cluttered and overwhelming as the feature surface has grown.
Who Apollo.io is actually for.
The 81 percent small-business skew on Capterra is not an accident. Here is where Apollo belongs and where it does not.
Apollo.io is the right choice for small and mid-market outbound teams selling into the US who want database, sequencing, and dialling under one subscription and will eyeball data before sending. It is the wrong choice for teams reliant on international or mobile data, and for any organisation that needs to be able to exit or shrink a contract mid-term.
Frequently asked
How much does Apollo.io cost?
Free is $0, Basic is $49 per user per month, Professional is $99, and Custom is quoted. The seat price is only half the picture, because credits for enrichment and export are the metered part of the bill and are the harder cost to forecast.
How do Apollo credits actually work?
Credits are spent on enrichment and on every exit from Apollo, including CSV export and CRM sync. Email enrichment costs 2 credits per record and phone numbers 8. Credits expire at the end of your billing cycle and do not roll over, and they are consumed whether or not the data returned is usable.
Is Apollo's data accurate?
Business email for US contacts is its strength and reviewers rate it highly. Phone numbers and international coverage are its weaknesses, and data decay is the most common complaint, with one reviewer estimating 10 to 15 percent of records carry outdated information.
Can I cancel Apollo mid-contract?
Not for a refund. Apollo's published terms state fees are non-cancelable and non-refundable, there are no refunds for partially used services, and subscriptions auto-renew unless you give 30 days' written notice. Mid-term downgrades do not generate a refund either.
Is the free plan actually useful?
More than most. With a verified corporate domain you get 10,000 credits a month, which is enough to test data quality on your own target market properly. Without a corporate domain it drops to 100 credits, and free accounts can only connect Gmail.
How does it compare to the alternatives?
Sales intelligence tools differ most on data coverage for your specific market and on how they meter usage. Both matter more than the feature list, and both deserve a proper comparison rather than a paragraph at the end of a review.
The edges of this review
Every review has limits. Rather than fill them with estimates, here is exactly what we could not confirm from a public source, so you know which questions to ask the vendor yourself.
- Per-plan credit allocations for Basic, Professional, and Organization. Apollo's plan comparison table renders client-side and never appears in the served page, so we could not confirm them.
- Whether the $49 and $99 figures are monthly-billed or annually-billed rates, and any annual discount. Apollo's structured data tags both as monthly but the rendered page could not be read to confirm.
- Organization plan pricing and seat minimums. Capterra lists Custom at $5,000 a year, which is third-party and unconfirmed by Apollo.
- Whether the current live plan names are Free, Basic, Professional, Organization or Free, Basic, Professional, Enterprise. Apollo's knowledge base and its own structured data disagree.
