Apollo is a massive B2B database that also sends. But roughly one in three records is stale, reported bounce rates run 15–35%, and it sends through shared servers with weak deliverability controls. OutreachFox pairs waterfall-verified data with private sending infrastructure.
Credit where it's due
The gap
Independent tests put Apollo's data accuracy around 65% overall — and lower outside the US — with bounce rates that regularly hit 15–35% (the safe ceiling is under 2–5%).
Teams send at scale on the strength of that label and torch their domain reputation when the data turns out stale.
Sending runs on shared infrastructure, there's no true LinkedIn automation, and the credit system clouds real cost.
As reviewers put it: Apollo is built around the database, not around inbox placement.
