Is your email set up correctly?

Paste a domain, IP, hostname or email address. We’ll pick the right check and give you a plain-language verdict in seconds.

Stop spoofing

Without enforced DMARC, anyone can send mail as your domain. Most domains never check.

Reach the inbox

One broken record or a single blocklist hit quietly sends your mail to spam.

Catch the drift

Records that pass today silently break tomorrow. The damage shows up as lost mail.
