Part 01 · Overview

Welcome

What it is, who it suits, its grades and the ten things to know first

2.6

GPA, above 15 of the 15 other email verification and deliverability tools we grade

DeBounce cleans email lists: it validates files in bulk, checks sign-ups in real time through an API or a JavaScript form widget, and imports lists straight from email platforms such as Mailchimp, HubSpot and Klaviyo. It also finds names behind addresses and can recheck a list every month. It does not warm up inboxes or manage DMARC. Credits are sold in packs that never expire, from $15 for 5,000.

To get you started, here are 9 things to know about DeBounce, taken from its own pages and our grades.

    Web.

  5. 5

    Bulk list validation

    Upload a list or import one from a connected email platform, and duplicates are removed free before checking. Greylisted checks are retried to cut unknown results.

  6. 6

    API and form widget

    A validation API and a JavaScript widget check addresses at sign-up, with a WordPress plugin and Zapier for no-code setups.

  7. 7

    Catch-all validation

    A deeper check of addresses on accept-all domains, at 10 credits per address instead of 1.

  8. 8

    A 2.6 GPA, above 15 of 15

    That is against the other email verification and deliverability tools we grade, on value, the free plan, features, ease of use and platforms.

The report card

Best for the cheapest pack for cleaning a list

DeBounce cleans lists and checks sign-ups, with a WordPress plugin and imports straight from Mailchimp, HubSpot and Klaviyo. It's the cheapest of the list cleaners for 10,000 checks, at $25, and the credits never expire. Catch-all checks cost 10 credits each, though, and there's no warm-up or DMARC.

ToolGPA report cardDeBounceGraded Oct 18, 2026
SubjectGradeComment
Value for moneyB$25 for a one-off 10,000 checks, taxes included, and the credits never expire. That's the cheapest among its listed rivals: Clearout is $32 a month billed yearly, MillionVerifier $39, Bouncer and Emailable $60 and ZeroBounce about $129.
Free plan and trialCNo free plan, but 100 free credits with no card. Enough to test a sample of your list, not to clean it.
FeaturesCIt does the checking job fully: bulk files, an API and form widget, catch-all checks, name lookups and monthly list rechecks. That's a smaller job, though: no warm-up, placement tests or DMARC, and catch-all checks cost 10 credits each.
Ease of useBNo App Store rating on record, but nothing to set up: upload a list or import it from a connected email platform, and duplicates are removed free before checking.
Platforms and integrationsBWeb, an API and a JavaScript widget, with Mailchimp, HubSpot, Klaviyo, ActiveCampaign, Google Sheets, SendGrid, a WordPress plugin and Zapier. No phone or desktop app.
Grade point averageGood, out of 4.02.6

An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.

Who DeBounce is for

  • Great if you want the cheapest way in, at $15 for 5,000 checks
  • Good for WordPress sites that want sign-up forms checked
  • Handy when your list lives in Mailchimp, HubSpot or Klaviyo

Who it is not for

  • Tight if your list is full of catch-all domains, at 10 credits a deeper check
  • Skip it if you need warm-up, placement tests or DMARC

Good to know

Good for

  • Small senders who need a cheap first pack
  • Teams importing lists straight from Mailchimp, HubSpot or Klaviyo
  • WordPress sites that want sign-up forms checked

Worth knowing

  • Catch-all checks cost 10 credits each and enrichment 20, so they use up a pack much faster than plain validation.
  • The pricing page also offers a monthly option at 8% below pay-as-you-go; its prices show only in the calculator.
  • DeBounce verifies addresses only; it has no warm-up, inbox placement tests or DMARC tools.

Keep it, or make your own?

Whether this is something you could build for yourself with an AI app builder, and what you would give up.

Keep it

Nothing DeBounce does is plain enough to make in a weekend. The 3 things listed below take a company.

It is one of the better ones too: its GPA of 2.6 is higher than 15 of the 15 other email verification and deliverability tools we grade. It costs $15, paid once.

What you could not

  • Checking that an address exists without writing to it.
  • It plugs into other products, Mailchimp, HubSpot and Klaviyo among them, and has an API.
  • Hooks into the device itself: widgets.

What this rests on. DeBounce’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
