Email Address Validator

Check up to 50 email addresses: format, domain, MX mail servers, disposable inboxes, role addresses and typos.

How do I check if an email address is valid?

Paste up to 50 addresses and the validator checks each one’s format, whether the domain exists and has MX mail servers (or a null MX that refuses mail), and flags disposable inboxes, role addresses like info@ and common typos such as gmial.com, marking each as Valid, Risky or Invalid.

Why validate emails?

Bounced emails hurt your sender reputation and deliverability. Cleaning sign-up forms and mailing lists of invalid and disposable addresses keeps your campaigns out of spam folders.

What we do not check

We do not connect to the mail server to ask whether a specific mailbox exists ("SMTP verification"): many servers accept every address or block such checks, and doing it at scale can get the checking server blacklisted. A valid result means the address can receive mail at the domain level.

Frequently asked questions

Is it free?

Yes, up to 50 addresses per check.

Do you store the addresses?

No, they are only used for the check.

What is a role address?

A shared inbox such as info@, sales@ or support@ — fine for business, but less engaged in newsletters.
