# ZeroBounce

> Email list verification with warm-up and DMARC monitoring in one plan

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.

## Key features

- **Email validation:** Checks lists by file upload or real-time API and flags invalid, catch-all, disposable, role-based, abuse and spam-trap addresses. Unknown results and duplicates are free.
- **AI scoring:** An AI model scores each address for quality at one extra credit, which helps decide whether to send to catch-all and other uncertain addresses.
- **Email Finder:** Finds a person's work address from a name and company domain, at 20 credits per successful search; unknown results cost nothing.
- **Warm-up and placement tests:** ZeroBounce ONE includes warm-up through a seed network, inbox placement tests against 20+ providers and email server tests.
- **Blacklist and DMARC monitoring:** Monitors IPs and domains on blacklists and gathers daily DMARC reports for one domain on the ONE plan.
- **API, SDKs and iOS app:** A validation and scoring API with SDKs in 16 languages, an MCP server, and an iOS app for checking lists from an iPhone or iPad.

## Good for

- Marketers cleaning large lists before a campaign
- Developers checking sign-ups through an API
- Small senders who want verification, warm-up and DMARC on one bill

## Worth knowing

- Warm-up and DMARC monitoring come only with ZeroBounce ONE, and it covers a single DMARC domain.
- Unused tests, monitors, searches and warm-up seeds on ONE do not roll over; only verification credits do.
- The FAQ says credits never expire with an active ONE subscription; otherwise expiry rules may apply depending on when they were bought.
- The free credits need a business or premium email domain at sign-up.

## ToolGPA grades

**GPA: 2.4 out of 4**, graded Oct 18, 2026. 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.

- **Value for money: D.** About $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.
- **Free plan and trial: C.** A 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.
- **Features: B.** The 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.
- **Ease of use: B.** No 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.
- **Platforms and integrations: B.** Web 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 it, 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.

- You could not: A network of real inboxes that open and answer your emails.
- You could not: Checking that an address exists without writing to it.
- You could not: Reading the reports inbox providers send about your domain.
- You could not: A real app for iOS. Something home-made would be a web page.
- You could not: It plugs into other products, Mailchimp and Zapier among them, and has an API.
- You could not: AI features, unless you pay a model provider for each request yourself.
- You could not: What a company asks for before it lets staff use something: roles and permissions.
- You could not: The depth: we grade its features B, which means it covers the whole job.
