Free domain health check. Get one plain grade.
Enter your domain to see, on one page, whether people can email you, whether your emails are likely to land in spam, whether scammers can pretend to be you, and whether your domain is close to running out.
How the grade works
We check five parts of your domain and mark each one good, needs attention, or a problem.
- A: every part we could check is good.
- B: one thing needs attention.
- C: two things need attention.
- D: three or more things need attention, or one problem.
- F: two or more problems.
A part we could not check is marked not checked and never counts against you. If too many parts could not be checked, we say so instead of giving a grade.
What this check cannot see
It reads public records only, the same ones any inbox reads before it trusts your email. It cannot see your passwords, whether sign-in protection is switched on, who has access to your mailboxes, or whether auto-renew is on for your domain. Those live inside your Microsoft 365 or Google Workspace account and your registrar account.

Common questions
What does the domain health check look at?
Five things, from public records only: whether your domain can receive email, whether it lists the services allowed to send as you (SPF), whether your emails carry a digital seal (DKIM), whether inboxes are told to stop fake emails using your name (DMARC), and whether the domain registration is close to ending or unlocked.
How is the grade worked out?
Each part is marked good, needs attention, or a problem. All good is an A. One thing needing attention is a B, two is a C, and three or more is a D. One problem is a D, and two or more problems is an F. A part we could not check is marked not checked and never lowers your grade.
Does a good grade mean my email is safe?
No. It means the public settings that inboxes rely on are in place. It cannot see passwords, sign-in protection, who has access to your mailboxes, or whether a message actually passed its checks. For that, we look inside your Microsoft 365 or Google Workspace account.
Is the share link private?
The link only holds your domain name. Anyone who opens it runs a fresh check of the same public records anyone can look up. Nothing about the check is saved on our side.
Why is there no spam list check?
Spam lists are checked by the address of the server that sends your email. If you use Microsoft 365 or Google Workspace, that is a shared server run by Microsoft or Google, so the answer would not be about you. If you run your own mail server, use our email blacklist checker.
My grade went down after I changed a setting. Why?
Public records can be cached for a while after a change, and this check may show answers up to 5 minutes old. Wait a little and run it again. If it still looks wrong, the change may need finishing in your DNS host or mail service.
