Privacy

What we keep when you run a spam test, and for how long.

supermail creates a one-time inbox so you can send a test message from your mail server.

We store the generated report and a copy of the raw message on the server disk (not only in RAM) so a deploy or restart does not erase a ready share link and so you can retest the same email after DNS changes without resending.
Waiting inboxes expire in about 30 minutes if no mail arrives.
Ready reports and raw messages stay reachable by share link for about 7 days across restarts, then are removed.
We do not sell message content. Logs may keep connection metadata (IP, time) for abuse control.
DNS lookups (SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI, DNSBL) use public DNS for the domains in the message.
