Features
DNS authentication
SPF, DKIM, DMARC and friends, generated and verified for you.
We generate the records for your domains, publish them through your DNS provider, check they propagated and keep watching for changes.
What you get
Records built by one library
SPF, DKIM keys, DMARC, MX, PTR guidance, MTA-STS and TLS-RPT come from the same generator the installer uses. Nothing on your server invents its own keys.
Publish in a click
Connect your DNS provider and review the exact changes before they are applied. Every change can be rolled back.
Or copy the records
Prefer to do it by hand? Get each record with plain instructions, ready to paste.
A checker that explains itself
Lookup counts, duplicate records, weak keys and policy gaps are called out with the exact fix.
Propagation you can trust
We confirm each record is visible before telling you it worked.
Drift alerts
If a record changes or disappears, a monitor tells you.

Questions
Do you need access to my registrar?
Only to the DNS provider that hosts your zone, with an API token you create and can revoke. Manual mode needs no access at all.
Who creates my DKIM keys?
We do, on our side, and show you the public record. Private keys never come from software running on your server.
Can you break my existing records?
Changes are shown as a diff before they apply, existing records are kept unless you choose otherwise, and each change set can be rolled back.
Other areas: Blacklist monitoring, SMTP and auth testing, Email validation, PowerMTA servers, Deliverability analytics.
