Where they pull apart

Apollo

Stands out: A large people database plus email sequences in one login, with MCP and a Chrome extension.

Watch out: Data quality varies by segment, and it does not match enterprise tools for intent data and org charts.

Not the right fit for

  • Buyers who need enterprise-class intent and org charts
  • Teams that want an ATS

Success.ai

Stands out: Even the Lite plan includes AI agents that write and answer emails, plus unlimited lookups in a 700M-plus contact database.

Watch out: Plans meter tokens and email volume. Lite gives 2,000 tokens and 5,000 emails a month on 10 warmed accounts, so heavy senders move up fast.

Not the right fit for

  • Teams that only need email verification
  • High-volume senders who want flat pricing
