Debounce
Email verification and list cleaning API.
From $0.00045/check Free tier API
Bottom line
Email verification and list cleaning API. Free credits to start; pay-as-you-go from $0.00045 per check.
Stands out for: 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 for: Per-check looks cheap until you run a million rows. There is no timed trial; free credits are the on-ramp.
Overview
Debounce is email verification and list cleaning. You upload a list or hit an API; it flags bounce, disposable, and role accounts. It is deliverability infrastructure, not contact data and not outreach.
Pricing leads with pay-as-you-go from $0.00045 per check and free credits with no card. Monthly credit packs sit on top. That free grant is not a 14-day trial. Integrations pages name developer-style connectors more than ATS logos.
