What you can do
MailHealth helps you check SPF, DKIM, DMARC, MX records, headers and basic email deliverability signals. Start from the main tool or choose a related task; the basic result stays available without mandatory signup.
About
How it works
Email checks read the provided domain, record or header and return a point-in-time interpretation.
Privacy and limits
Header analysis can stay local, while DNS checks need the domain or record being tested.
Deliverability depends on sending behavior, reputation and providers, not only DNS records.
