$39/2,000 credits Free tier MCP API
Why it comes up: Default verify if Emailable's rollover is not the differentiator.
Stands out: Validation plus quality scoring on one meter, with a real free 100-credit allowance and a public $99/month subscription.
Watch out: Pay-as-you-go starts at $39 for 2,000 validations if you do not want a subscription. Heavy lists will burn the 10,000-credit ONE cap.
Best for
- Recruiting and sales teams cleaning lists before send
- Ops that want validation as an API
- Desks that need scoring, not only deliverable/undeliverable

Read the ZeroBounce write-up · Emailable vs ZeroBounce
Why it comes up: Bulk list cleaning in a similar API motion.
Stands out: A long-running list-cleaning API used next to marketing and recruiting outbound, not a finder.
Watch out: Plans start at $49/mo, sold as credit packs. You still need a finder if the list has no addresses yet.
Best for
- Ops cleaning large outbound lists
- Teams that want verification as an API
- Marketing and recruiting desks sharing one cleaner

$0.00045/check Free tier API
Why it comes up: PAYG per-check if you do not want a monthly pack.
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.
Best for
- Ops cleaning lists before a send
- Developers wiring a verify API
- Teams that want pay-as-you-go rather than a seat

Read the Debounce write-up · Emailable vs Debounce
Why it comes up: Verify plus find if you need both.
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.
Best for
- Ops that need realtime verification in the app
- HubSpot and Lemlist users
- Teams that want find plus verify in one login
