Email Validator

Typos in email lists cause bounces and skew campaign reports. Paste your addresses, one per line, and the validator checks each one so you can mark or remove the invalid ones.

How to use E-Mail Validator

  2. Choose what to do after validation: Mark E-mails as Valid or Invalid or Delete Invalid E-mails.
  3. Click Validate E-Mails and copy the result.

When it comes in handy

  • Cleaning a mailing list before an import or a campaign.
  • Spotting typos in addresses collected from forms.
  • Removing malformed entries from a data export.

Frequently asked questions

Does a valid result mean the mailbox exists?
No. The check looks at the format of the address. Only sending a message, or a verification email, shows that a mailbox is real.
What makes an address invalid?
Typical problems are a missing @ sign, spaces, missing domain or unusual characters in the wrong place.
