Apollo.io review

This review is based on Apollo’s public pages and third-party ratings, checked on 4 October 2026. The rating out of 10 is the editor’s own judgement. The focus is on link building outreach, not general sales use.

How it works

Apollo calls itself an AI system for go-to-market teams. At its centre is a database that Apollo puts at more than 240 million contacts and 30 million accounts, which it says is regularly updated. Around that sit tools to write and send outreach, follow up automatically and enrich records.

The home page lists deliverability features by name: domain warming, inbox rotation and reputation monitoring. It also lists a Chrome extension that shows verified emails and phone numbers while you work in other tools, and compliance support for GDPR and CAN-SPAM. The database size is Apollo’s own figure.

Use for link outreach

Apollo is not a link building tool. Its pages do not mention publisher metrics, link monitoring or tracking placements. What it can do for a link builder is put a name and an email against a company website, then send a sequence.

That is most useful when your targets are businesses: partner links, supplier and customer pages, unlinked mentions on company sites, or resource pages run by a marketing team. A sales database is a weaker fit for independent bloggers and journalists. For those, see building a media list and finding contacts and verifying emails.

Data quality deserves a check before you send. Some Trustpilot reviewers report wrong contact details, so verify addresses first. A tool such as Hunter.io includes a verifier.

Pricing

Plan	Price	What Apollo says it adds
Free	$0	Light usage
Basic	$49 per user a month, billed annually	Unlimited sequences, CRM integrations
Professional	$79 per user a month	Workflow automation, AI research, dialer
Organization	$119 per user a month, 3-user minimum	International dialling, SSO, admin controls

We could not read the price table on Apollo’s pricing page on 4 October 2026. The page loaded with plan names and descriptions only. The figures above come from an article on Apollo’s own site, dated 17 September 2026, which quotes its pricing page. That article states the billing period for Basic only, so confirm the rest before you buy.

The same article explains that each plan carries a credit allowance, that credits do not roll over between billing cycles, and that a verified email costs up to one credit while a mobile number costs several.
