How Apollo.io bills you
The pricing model is per credit (email 1, phone 8). Sales-platform giant whose enrichment API rides on a massive contact DB, with a generous credit free tier but API depth gated behind paid seats. Best suited to: sales engagement plus enrichment.
What to watch for on the bill
- Phone numbers cost 8 credits each yet user-reported direct-dial accuracy is only ~50–70%
- Credits expire every billing cycle with no rollover and no refund on unused balance
- API access is gated, unavailable on the Basic plan, scaling only with higher tiers
- Persistent billing/refund/cancellation complaints and account suspensions on Trustpilot (2.9/5)
