Will this email bounce?

Check an address before you send. We test its syntax, the domain's mail servers, and whether it's a disposable or role address, then give you a confidence score.

5 free checks a day. Checking never sends an email to the address.

What we check

Syntax against the email standard, MX records for the domain, a list of disposable-inbox providers, and common role prefixes like info@ and sales@.

What catch-all means

Some domains accept mail for every address, real or not. No verifier can confirm a mailbox on those domains, so we label them rather than guess.

Why bounces matter

Mailbox providers watch bounce rates closely. Keeping them low protects your domain's reputation. Set up SPF, DKIM and DMARC too.

Do this for a whole list, not one at a time.
