Where they pull apart

Watch out: Email only: there is no LinkedIn channel and no finder in the same login.

Not the right fit for

Teams that need LinkedIn in the same sequencer

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.
