Apollo.io Review — Honest Pros, Cons & Pricing (2026)

Category: B2B contacts database with outreach capabilities

Also known as: apolloio, apollo.io.

Overview

Apollo.io is primarily a B2B contacts database with 275M+ verified business contacts, making it one of the largest prospecting databases available. The platform also includes basic outreach and sequencing capabilities, though most cold email professionals use Apollo primarily for prospecting and pair it with a dedicated sending platform like Instantly or Smartlead for actual campaign execution. Apollo's generous free tier makes it an excellent starting point for teams building their prospect lists.

Pricing

Free tier with limited credits. Basic: $49/user/month. Professional: $79/user/month. Organization: $119/user/month (annual pricing).
