Best for list cleaning with warm-up and DMARC on one bill
ZeroBounce is a thorough list cleaner, with AI scoring, an email finder and an iPhone app, and its ONE plan adds warm-up, inbox tests and DMARC for one domain. That breadth costs, though: 10,000 checks run about $129 as a pack, the dearest of the list cleaners it's listed beside. If all you need is a clean list, cheaper tools do that part.
Who ZeroBounce is for
- Great if you want list cleaning, warm-up and DMARC for one domain on one bill
- Handy when your developers want an API with ready-made SDKs
- Good for checking a list from an iPhone or iPad
Who ZeroBounce is not for
- Pricey if you only need a list cleaned, at about $129 for 10,000 checks
- Tight if you send from several domains, as ONE watches DMARC for just one
Why ZeroBounce gets a 2.4
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- DValue for moneyAbout $129 for a one-off pack of 10,000 checks, or $79 a month billed yearly on ONE for 10,000 credits a month with warm-up and DMARC thrown in. Its listed rivals charge $39 to $70 for 10,000, so even ONE is the dearest way to check a list.
- CFree plan and trialA real free plan: 100 checks a month that refill, plus one inbox test, one server test and one blacklist monitor. You need a business email to get it, and 100 checks won't clean a list.
- BFeaturesThe one list cleaner here that touches all three jobs: validation with spam-trap and abuse flags, AI scoring and an email finder, then on ONE, warm-up seeds, 100 inbox tests, blacklist monitors and DMARC reports. DMARC covers just one domain, though.
- BEase of useNo App Store rating on record. The core job needs nothing set up: upload a list and download it cleaned. There's an iPhone and iPad app for checking lists away from your desk, too.
- BPlatforms and integrationsWeb and an iOS app, an API with SDKs in 16 languages and an MCP server, plus Mailchimp and Zapier. No Android or desktop app.

Keep ZeroBounce, or make your own?
Keep it
To replace ZeroBounce you would be making a network of real inboxes that open and answer your emails. That is not a weekend's work, with an AI app builder or without one.
It costs $39, paid once.
What you could not
- A network of real inboxes that open and answer your emails.
- Checking that an address exists without writing to it.
- Reading the reports inbox providers send about your domain.
- A real app for iOS. Something home-made would be a web page.
- It plugs into other products, Mailchimp and Zapier among them, and has an API.
- AI features, unless you pay a model provider for each request yourself.
- What a company asks for before it lets staff use something: roles and permissions.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. ZeroBounce’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.
What is ZeroBounce?
ZeroBounce is mainly a list cleaner: it checks addresses in bulk or through an API, flags spam traps, abuse and catch-all addresses, and can score each one for quality with AI. Its ZeroBounce ONE subscription also covers the other two jobs in a small way, with warm-up seeds, inbox placement tests and DMARC monitoring for one domain. Credits come as pay-as-you-go packs or a monthly allowance.
ZeroBounce has a free plan. Paid plans start at $39 one-time for 2,000 verification credits. See every plan
