What this means for your email list

Should you accept addresses at this domain?

Treat these as low-value. People use mailinater.com to avoid giving a real address, so the contact is unlikely to reply, buy or come back. A real-time check at signup stops them before they enter your list.

Sender authentication

mailinater.com has a strict DMARC policy (reject): mail that fails authentication is refused, which protects its brand from spoofing and means anyone sending as mailinater.com must have SPF and DKIM set up correctly.
