Why is your cold email landing in spam?
Enter your sending domain. In about 30 seconds you will see whether your SPF, DKIM, DMARC, and MX are set up to reach the inbox, and exactly what to fix if they are not.
Checking DNS records…
What we check
The four records that decide the inbox.
SPF
Tells receivers which servers may send for your domain. Missing or broken SPF is a fast track to spam.
DKIM
Cryptographically signs your mail so receivers trust it is really you. Without it, your mail looks forgeable.
DMARC
Tells receivers what to do with mail that fails SPF or DKIM. No DMARC means no policy, and weaker trust.
MX
Confirms your domain can receive mail, which receivers expect from a legitimate sender.
