Every sender checked
Each mail that arrives is checked with SPF, DKIM and DMARC, so you know it really comes from who it says.
SPF, DKIM and DMARC are the checks that tell whether a mail really comes from the domain in its From line. We run all three on every mail that arrives and show the result when it matters.
A mail that fails them doesn't just disappear: it gets a clear warning, so you decide.
- Checked on arrival, not when you open it
- The full original with its headers is always one click away
