What the check measures
The DNS records that decide whether your emails are trusted or land in spam, and whether someone else can send email pretending to be you.
- SPFWhich servers may send email for your domain, and whether the policy really rejects the rest.
- DKIMA signature on every message proving it wasn’t altered. We probe the common selectors.
- DMARCWhat receivers should do with fakes, and whether you get reports about them.
- MXWhether your domain can receive replies at all.
Check everything at once.
