DeBounce

Pay-as-you-go email list verification

Email Verification

Overview

DeBounce is a bulk email verification service that cleans lists by removing invalid, disposable, and risky addresses before you send. It runs on a credit model with no subscription, so you buy verification volume as needed and the credits do not expire. Beyond batch list cleaning it offers an API, real-time verification, catch-all detection, and lightweight data enrichment. It is a focused utility rather than a full deliverability or sending platform.

Who it's for

  • →Teams cleaning purchased or aged email lists before a campaign
  • →Senders who want pay-per-use pricing without a monthly commitment
  • →Developers needing a verification API to gate signups in real time
  • →SMBs running outbound or newsletter programs on a budget

Not for

The honest take

Where it breaks

Catch-all and accept-all domains remain the hard limit, returning ambiguous results that DeBounce cannot fully resolve, and the pay-as-you-go model means high-frequency continuous verification can cost more than a flat-rate competitor at scale.

The verdict

DeBounce is a solid, no-frills list verifier whose non-expiring credits and free starter allowance make it easy to adopt for occasional or budget-conscious cleaning. It is best treated as a focused utility for list hygiene rather than a deliverability platform, and like all verifiers it should be sanity-checked on catch-all-heavy lists.

FAQ

How does DeBounce pricing work?

It is credit-based pay-as-you-go. One credit verifies one email, catch-all checks cost 10 credits, and enrichment costs 20 credits. You buy credits in volume tiers starting around $0.00045 per check, and they never expire.

Is there a free option?

Yes. New accounts get 100 free credits with no credit card required, enough to test accuracy on a small sample before buying.

Does DeBounce send emails?

No. It verifies and cleans lists; you still send through your own ESP or sending platform.

Can it handle catch-all domains?

It flags catch-all and accept-all addresses, but no verifier can confirm these with certainty, so results carry residual risk.

Is there an API?

Yes. DeBounce provides an API for real-time verification and integration into signup flows and custom apps, included across plans.
