Free email verifier
# Is this email real?
Type an address and press Run. You get a verdict (valid, invalid, risky or unknown), an A–F risk score and every check behind it, from the same live API that agents use.

POST api.askravn.com/v1/tools/validate_emaillive
validate_email

POST /v1/tools/validate_emailPress Run: this calls the real API.

What it checks
## The same checks your agent gets.
Results come from the live API, not a cached demo. The API returns the full response; the box shows the key fields.

- / 01
### Syntax
Catches typos, stray spaces and malformed addresses before anything else.
- / 02
### Domain and mail servers
Checks the domain exists and has mail servers (MX). No mail servers means the address can’t receive mail.
- / 03
### Disposable, role and free providers
Flags burner domains, shared inboxes like info@ and free providers like Gmail.
- / 04
### Catch-all domains
Some domains accept any address. We mark those risky rather than guessing.
- / 05
### Honest verdicts
If the mailbox itself wasn’t tested, `mailbox_checked` is false and the verdict is never valid.

For lists, [sign up](https://askravn.com/#start) for 1,000 free lookups or use [the email verification API](https://askravn.com/features/email-verification-api).Do you store the address I check?We keep a short-lived cache of the verdict so repeat checks are fast. We don’t add it to any data set. See [our data](https://askravn.com/data).Can I verify a whole list?Yes: `npx ravn enrich list.csv --tool validate_email --column Email`, or ask Claude with the [MCP server](https://askravn.com/mcp-server) connected. See [verifying a list](https://askravn.com/use-cases/verify-email-list).Why is a real address marked risky?Usually the domain is a catch-all, so no checker can prove the mailbox exists. Send carefully, or confirm it another way.
