The only email infrastructure that closes the deliverability loop end-to-end. No bolt-on tools. No vendor sprawl. EU-native.
Know in 1 second if your email was delivered. Not 30 seconds via webhook. Not "accepted". Delivered.
Paste 4 records once. Truncus owns the rest forever — SPF, DKIM, DMARC, MTA-STS, plus weekly drift correction.
Truncus runs its own DMARC ingestion endpoint, parsing aggregate reports from Gmail, Yahoo, and Outlook into your account — no third-party deliverability service required.
Start setup in under a minute.
See if your domain is ready to send email — SPF, DMARC, and MX in seconds.
