$39/2,000 credits Free tier MCP API
Why it comes up: ZeroBounce adds scoring and a wider deliverability suite around verification, where Bouncer keeps the core product narrow and prices it per credit.
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 · Bouncer vs ZeroBounce
Why it comes up: EmailListVerify is cheaper at the entry tier, $6.99 per 1,000 credits against $8, if unit cost matters more than the extras.
Stands out: Pay-as-you-go credits never expire, the REST API is included, and a native MCP endpoint is documented.
Watch out: The 100 free checks are a signup allowance, not a free-forever plan. Email finder uses 5 credits per find at medium or higher confidence.
Best for
- Marketers cleaning lists before a send
- Developers verifying emails on signup forms
- Agencies splitting credits between verify and find

Read the EmailListVerify write-up · Bouncer vs EmailListVerify
Why it comes up: Emailable gives 250 free credits to start against Bouncer's 100, and discounts subscriptions rather than selling extras separately.
Stands out: Never-expiring credits. Most verify tools zero you out at month-end.
Watch out: The $32.30 figure is the annual 5,000-credit rung (down from $38). Monthly is higher. This is verify, not find.
Best for
- Ops that hate expiring credits
- Developers wiring a verify API
- Teams cleaning lists on a schedule that is not monthly

$0.00045/check Free tier API
Why it comes up: Debounce is the volume play, with published per-check pricing well below Bouncer's entry tier and no form-protection or MCP layer.
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
