Email Continuity for SaaS

Your email doesn't stop when your provider does.

Add a guaranteed execution layer to your product email execution. Keep critical user communications flowing — even during outages, restrictions, or vendor failure.

You rely on email. You don't control it.

If your email provider fails — what happens to your product?

User authentication and login flows break. Onboarding sequences stop mid-flow. Billing and invoice emails fail silently. System alerts and incident notifications don't arrive.

Most platforms don't have a fallback. They only discover that when it's too late.

“EU hosting” doesn't mean control.

Even if your data is stored in EU regions:

  • Your provider is still a single point of failure.
  • You depend on their infrastructure, policies, and uptime.
  • You cannot reroute or recover independently.

You have redundancy inside a provider. Not outside it.

Truncus adds a second layer of control.

Truncus sits alongside your existing email setup. No migration. No replacement. No disruption.

Fallback sending

A separate sending layer for critical emails, independent of your primary provider.

Independent routing

If your provider is unavailable, Truncus routes emails through its own infrastructure.

Full visibility

Complete delivery logs, failure tracking, and audit trails for every email sent.

How it works

Three steps. No migration. Operational in hours.

1

Connect

Integrate Truncus alongside your current provider. Your existing setup stays untouched.

2

Monitor

Track delivery across both layers. Detect failures before they reach users.

3

Fallback

If something breaks, Truncus takes over — automatically or on demand. No manual intervention required.

Critical emails you cannot afford to lose.

These are the emails your platform sends every day. If they fail, your users churn.

Authentication flows & password resets

Broken login flows block users from their accounts — the fastest path to cancellation.

User onboarding & activation emails

Stalled onboarding means users never reach value — they sign up and disappear.

Billing notifications & invoice delivery

Missing invoices create payment disputes and erode trust in your billing process.

Incident alerts & system status updates

Undelivered status updates during outages multiply support load and damage credibility.

If these fail, your users churn.

Built for control, auditability, and platform requirements.

Designed to support SaaS platform requirements around uptime guarantees, data handling, and customer trust.

Hosted in EU regions

AWS eu-west-1 (Ireland). Data stays in the EU by default.

Full delivery logs

Every email tracked end-to-end. Exportable audit trails.

Clear data boundaries

You control what data enters Truncus. No data mining, no profiling.

Vendor independence

No dependency on a single vendor for critical email flows.

Built for platforms where communication failure means user churn.

Truncus is designed for SaaS platforms where email is not optional infrastructure — it's the connective tissue of every user relationship. We work with teams that need to prove continuity, not just promise it.

Pilot programs available for qualifying platforms

What happens if your email provider is unavailable tomorrow?

Most platforms don't know. Until they experience it.
