Die einzige E-Mail-Infrastruktur, die die Zustellbarkeitsschleife schließt. Keine Bolt-on-Tools. Kein Vendor-Sprawl. EU-Datenresidenz.

Setup in unter einer Minute.
Idempotency-Key is mandatory on every send — architecture, not a best-practices footnote. Replay a call, get the original message id back as duplicate. Try it twice and watch.
send_sync returns terminal delivery status in the response body. No endpoint to host, no polling loop to write. Takes longer than 25 seconds? You get an explicit pending and an id to poll — never silence.
claude mcp add truncus -- npx -y @vanmoose/mcp-server — send, validate, events, stats, domains, suppression. Idempotency keys injected automatically.
OpenAPI 3.1. llms.txt, current. Stable machine codes on every error — DOMAIN_TYPE_MISMATCH, MONTHLY_LIMIT_EXCEEDED, granular provider_code on failures. Your agent branches on codes, not prose.
Öffentlich. Keine Auth. Kein Konto. Nie gecacht — no-store bei jeder Antwort. Auf 600 Requests/Minute pro IP begrenzt, damit Monitoring nie anschlägt. Richte deins auf /api/status, noch bevor du ein Konto hast.
→ Verify it yourself. Replay the duplicate key. Fetch the status JSON. Every claim on this page has a curl.
Truncus halts a domain at 2.0% bounce or 0.07% complaint — tighter than the thresholds that get SES accounts suspended. Nobody’s bad list burns the pool. Including yours.
Total provider failure on the async path lands in a durable queue — retried at 30s, 2m, 8m, 30m, 2h, then dead-lettered, replayable, watchable. A published schedule, not a promise.
Truncus versendet ausschließlich transaktionale E-Mails. Kaltakquise und Marketingkampagnen sind auf Kundenkonten nicht erlaubt.
Flagged domains are born held — their first send is blocked before any provider sees it. Fingerprinting, burst detection, auto-pause. Boring infrastructure, on purpose.
Primary on AWS SES (Ireland); async sends fail over to Scaleway TEM (France).
Sehen Sie, ob Ihre Domain zum E-Mail-Versand bereit ist — SPF, DMARC und MX in Sekunden.
→ Verify it yourself. The breaker thresholds, the backoff schedule, the 403 — all documented, all reproducible.
Your email content is sent and stored in the EU: SES eu-west-1, Scaleway fr-par, Supabase Frankfurt. Run dig +short TXT mail.truncus.co and see both providers yourself.
What we won’t claim: residency is not sovereignty. US-incorporated providers sit in the path and are CLOUD-Act reachable — our pricing page says so in plain text. If a vendor claims otherwise while running on AWS, ask them to put it in their DPA.
The sub-processor table in ours is complete — including the parts vendors usually omit.
99.5% uptime SLA, in writing, with the honest disclaimer no SLA can offer: inbox placement isn’t guaranteed by anyone.
→ Verify it yourself. Run the dig on mail.truncus.co. Read the DPA. It’s all public.
