For telehealth & digital health

Your email infrastructure is a compliance risk.

Built for telehealth companies that need deliverability, audit trails, and control — with EU-resident sending and no silent failures.

The regulatory reality

The FDA issued 70+ warning letters to telehealth companies in the last enforcement wave. State attorneys general are investigating patient communication practices. Data breaches carry per-record penalties that scale with volume.

Most telehealth companies didn't fail because of product. They failed because their communication layer wasn't defensible.

If a regulator asks “what exactly did you send this patient, when, and can you prove it?” — your email infrastructure needs to answer that question in minutes, not weeks.

What your current setup actually looks like

Silent failures — a send fails and nothing tells you, during a patient notification window.

No audit trail — you can see "sent" but not "accepted" or "what was in it."

No control over messaging risk — any engineer can send anything from any domain.

No error visibility — when a send breaks, you find out from the patient, not your logs.

Marketing and transactional email sharing the same domain reputation.

That's not infrastructure. That's liability.

What Truncus adds

A layer between your application and email delivery. EU-resident sending, full audit logs, policy enforcement, and synchronous delivery confirmation.

EU-resident sending

AWS SES in Ireland (eu-west-1). Circuit breakers detect failures fast and surface the exact error — no silent failures in your patient communication.

Full audit trail

Every message logged: what was sent, when, to whom, and whether the receiving mail server accepted it. Searchable. Exportable. Defensible.

Pre-send validation

Confidence scoring catches problems before send. Bad addresses, suppressed recipients, and domain health issues flagged before they become incidents.

Policy enforcement

Define what can be sent through each domain and stream. Outreach and transactional email are isolated at the API level. Violations blocked, not warned.

Operations API

Delivery guarantees: best_effort, at_least_once, exactly_once. Durable retry queues with dead-letter recovery. Nothing gets silently lost.

1.04s delivery confirmation

send_sync returns delivery status before your application continues. Your system knows the receiving mail server accepted the message — not just that you fired it off.

Built in the EU

EU-hosted infrastructure

Sending through AWS SES in Ireland (eu-west-1). Email data stored in Frankfurt. Your patient data stays in the EU — end to end.

GDPR-native EU data residency Data stored in the EU Audit-ready logging

Growth without control gets you flagged.

Control without growth slows you down.

Truncus gives you both.

Built for healthcare email

Patient appointment reminders

Delivery confirmed in 1 second — the receiving mail server accepted the message. If a send fails, you get the exact error immediately, not silence.

Prescription notifications

Audit trail proves exactly what was communicated, when, and whether the receiving mail server accepted it. Searchable by patient, date, or message content.

Billing and payment emails

Operations API with at_least_once guarantee. Failed sends retry automatically. Dead-letter recovery catches edge cases.

Post-visit surveys and follow-ups

Pre-send validation prevents bounces. Domain reputation monitoring catches deliverability issues before they affect patient communication.

Marketing and outreach

Stream isolation keeps promotional email on separate domains. Marketing complaints never affect transactional deliverability.
