Connect your domain

One DNS record and every address on your domain becomes a private mailbox here. No account and no signup: the MX record is the proof that the domain is yours.

  1. Add this MX record at your DNS provider

    TypeMX
    Name@
    Priority10
    Value — the part you paste smtp.grabmail.io

    Delete every other MX record on the domain. Mail can only be delivered to one place, and a leftover record from a previous provider takes part of your traffic in silence. Verification below refuses a domain with more than one MX for exactly that reason.

  2. Verify it here and take your key

    We look up the record live. If it points at us, the domain is accepted within two minutes and you get the key that opens its mailboxes.

Nothing is stored about you — no email, no password, no account. Only the domain and a hash of its key.

What you get

  • Every address on the domain, created on the fly
  • Readable only with your key — the web inbox asks for it too
  • Your domain never appears anywhere on this site
  • The same API, and the same 5-day retention
  • Free, like the rest of it
