Will your email land in spam?

Type your domain or email address. We check MX, SPF, DKIM, DMARC and the major blacklists, and show exactly what to fix.

What we check

• MX: where mail for your domain is delivered.
• SPF: which servers may send as you.
• DKIM: a signature that proves the email wasn’t changed.
• DMARC: what receivers do with fakes.
• Blacklists: whether your mail server is listed as a spammer.
