The deliverability loop, closed

Send. Know it landed. See how the world received it.

The only email infrastructure that closes the deliverability loop end-to-end. No bolt-on tools. No vendor sprawl. EU-native.

send_sync

Know in 1 second if your email was delivered. Not 30 seconds via webhook. Not "accepted". Delivered.

Zero-touch DNS

Paste 4 records once. Truncus owns the rest forever — SPF, DKIM, DMARC, MTA-STS, plus weekly drift correction.

DMARC aggregator

Truncus runs its own DMARC ingestion endpoint, parsing aggregate reports from Gmail, Yahoo, and Outlook into your account — no third-party deliverability service required.
