Lookalike Domain Checker
See which domains close to yours are already registered. DMARC can't govern them, because each one is a separate domain.
What this checks
We test common variations of your domain: swapped letters, lookalike characters, added words, hyphens and other endings. Then we read public DNS to see which exist and how they're set up. The check doesn't look at your mailboxes or your messages.
What is a lookalike domain?
A domain registered to resemble another one, such as a misspelling or the same name with an added word.
Why doesn't DMARC stop these?
DMARC applies to the domain that publishes it. A lookalike is a separate domain with its own records. Our guide on how lookalike domains bypass DMARC explains why.
Is a lookalike always malicious?
No. Check whether it's set up for email, what its website shows, and when it was registered.
What should I do if one looks dangerous?
Report it to the registrar and the hosting provider, and block it in your email security tool. Our guide on taking down lookalike domains has the steps.
