Is your email landing in spam?

Enter a domain (e.g. yourcompany.com) and check whether SPF, DKIM, and DMARC are set correctly, the three things that decide whether your email gets delivered and whether anyone can impersonate you.

The tool queries only the domain's public DNS records. We do not store the domains checked. Anti-bot verification protects the server from automated abuse.

What does this mean?

SPF, a list of servers allowed to send mail from your domain (blocks spoofing).
DKIM, a digital signature added to every email, confirming authenticity.
DMARC, a rule telling recipient servers what to do with suspicious mail.
