Terms of service
Last updated October 28, 2026.
Free checker and AI assistant connector
The email checker on this site and the connector at spamfixer.com/mcp are free. They read public DNS records and report what they find. Results are provided as-is, for information only: DNS changes over time, some settings (such as DKIM keys on custom selectors) can't be seen from outside, and a good score doesn't guarantee that every email reaches the inbox.
Don't use the checker or connector to overload our service or anyone else's, for example by scripting large numbers of lookups. We rate-limit requests and may block abusive use.
The paid fix
When you hire us to fix your email setup, we agree the scope and price with you by email before starting. If we can't fix the problems we agreed to fix, you don't pay. You stay the owner of your domain and DNS, and you can revoke any access you give us at any time.
Liability
To the extent the law allows, we aren't liable for indirect or consequential losses, and our total liability for any paid work is limited to what you paid us for it.
Changes
We may update these terms; the date above shows the latest version.
