Clearout
Stands out: Realtime verify API plus bulk plus a finder (HubSpot, LinkedIn, Zapier, Make, Apollo, Lemlist named): one vendor for clean and find.
Watch out: The finder is an add-on rather than part of the base plan, and credit packs change often, so confirm the current pack on a demo before you budget.
Not the right fit for
- People who only need a $29 finder
- Teams that want NeverBounce-simple list clean
- Buyers who need a published price grid
Debounce
Stands out: A verification API with a public per-check floor and a free start, so no $35/mo gate if your list is small.
Watch out: Per-check looks cheap until you run a million rows. There is no timed trial; free credits are the on-ramp.
Not the right fit for
- People who need a finder
- Teams that want a sequencer
- Buyers who need a flat $32/mo all-you-can-verify
