# ZeroBounce vs NeverBounce: what an AI agent can replace

ZeroBounce vs NeverBounce, checked 2026-11-03: ZeroBounce's prices and free credits, NeverBounce's API and free list analysis, and what each adds past verification, with sources. Plus how an agent verifies emails per call.

## ZeroBounce vs NeverBounce, the short answer

Pick ZeroBounce if you want verification plus deliverability tools in one account: scoring, warmup, inbox placement tests and blacklist monitoring. Pick NeverBounce if you mostly clean lists and want a free bounce estimate before you verify, or a widget that checks emails on signup forms.

Checked 2026-11-03.

## Where ZeroBounce wins

Breadth around the inbox. ZeroBounce sells verification next to email scoring, an email finder, warmup, inbox placement tests and blacklist and DMARC monitoring, all on one credit balance. If a bounce problem is really a sender reputation problem, it covers more of it.

It also says it never charges for unknown results, so a list full of hard to check domains costs less than it looks.

## Where NeverBounce wins

A look before you pay. NeverBounce's API can run a free analysis of a list and return an estimated bounce rate, so you decide whether the full list is worth verifying. Its docs also ship a JavaScript widget for signup forms and advise letting valid, catch-all and unknown results through while blocking only disposable and invalid ones.

## Where looot fits

An agent does not need an account at either one to check emails. With one looot key it calls the email verification job and pays per check: ZeroBounce itself, MillionVerifier, BounceBan, LeadMagic and Scrubby, with batch endpoints on two of them. The live price of each is listed below.

NeverBounce is not in the looot catalog. Warmup, inbox tests and monitoring are not either, since looot sends no email.

## Endpoints priced live on the page

## The honest note

looot is not ZeroBounce and not NeverBounce. Each product does things looot does not, and the lists below name them. Use this page to decide which jobs an agent can take over, not which tool to choose.

## Jobs both do that an agent can take over

- Verify emails. Providers: millionverifier, bounceban, leadmagic, zerobounce, scrubby, hunter.

## What you keep ZeroBounce for

- Clean a whole list: partly covered. Two providers take a batch; with the others your agent checks the list one email per call.
- Inbox placement and warmup: not covered. looot sends no email, so it cannot test or warm up an inbox.
- Blacklist and DMARC monitoring: not covered. Watching a domain needs scheduled runs, not available yet.

## What you keep NeverBounce for

- Clean an uploaded list: partly covered. Two providers take a batch; with the others your agent checks the list one email per call.
- Automatic CRM re-checks: not covered. Re-checking a CRM's contacts on its own needs scheduled runs, not available yet.
- Upload a CSV in a web app: not covered. looot has no list upload screen; your agent sends the emails.

## Agent prompt for ZeroBounce jobs

Use looot to verify the email addresses I give you, mark each one as valid, invalid, catch-all or unknown, and return only the safe ones as a table. If you have not yet, set up https://looot.ai/skill.md first. Then search the looot catalog for each step, check the price of each endpoint before you call it, run the cheapest one that fits, and show me the results as a table.

## Agent prompt for NeverBounce jobs

Use looot to check the email addresses in the list I give you, drop the invalid and disposable ones, and return the rest with their status as a table. If you have not yet, set up https://looot.ai/skill.md first. Then search the looot catalog for each step, check the price of each endpoint before you call it, run the cheapest one that fits, and show me the results as a table.

## ZeroBounce vs NeverBounce: which one should I pick?

ZeroBounce if you want verification plus deliverability tools such as warmup, inbox tests and blacklist monitoring. NeverBounce if you mostly clean lists and want a free bounce estimate before you verify, or a widget for signup forms.

## How much do ZeroBounce and NeverBounce cost?

ZeroBounce's pricing page, checked 2026-11-03: pay as you go starts at $39 for 2,000 validations, and ZeroBounce ONE at $99 a month for at least 10,000 credits. NeverBounce's pricing page blocks automated reads, so we did not verify its prices: check neverbounce.com/pricing before you buy.

## Which is more accurate, ZeroBounce or NeverBounce?

Neither publishes a test you can repeat, and accuracy depends on your list: catch-all domains and new mailboxes are where verifiers disagree. Run the same 200 addresses through both, or through two providers on looot, and compare how many bounce when you send.

## Do ZeroBounce and NeverBounce have an API?

Yes. Both offer a real-time verification API and bulk list cleaning. ZeroBounce charges one credit per email checked by API or in bulk. NeverBounce's API v4 has a single check endpoint, bulk list jobs and a free list analysis.

## How do I test a list with ZeroBounce or NeverBounce before I verify it all?

NeverBounce's API runs a free analysis that returns an estimated bounce rate for the list. ZeroBounce gives 100 free validations each month with a business domain, enough for a sample. On looot, verify 20 addresses with two providers first and read the results before you run the rest.

## Is there a free alternative to ZeroBounce and NeverBounce?

ZeroBounce gives 100 free validations each month with a business domain, and NeverBounce offers a free list analysis. For an agent, looot has no plan at all: you top up a balance and pay for each check, with the price shown before the run.

## Can an AI agent verify emails without a ZeroBounce or NeverBounce account?

Yes. With one looot key an agent calls the email verification job on ZeroBounce, MillionVerifier, BounceBan, LeadMagic or Scrubby, one address per call or a batch on two of them, and drops the invalid ones before you send.
