Product philosophy
Email is not a channel.
It's infrastructure.
Syntr is built for teams who treat email as part of their product — not an afterthought.
- •Campaigns are long-running systems, not one-off sends
- •Signals matter more than schedules
- •Execution should adapt automatically
That's why Syntr centers around workflows, live activity, and coordinated actions — the foundations of modern email.
Infrastructure. Reliability. Determinism.
Syntr provides APIs and SDKs to integrate email directly into your product.
// Send transactional emails from your product
await syntr.send({
to: user.email,
template: "welcome",
data: { name: user.name }
});
// Done.Built for production systems
- •Transactional & lifecycle emails
- •Typed APIs with predictable behavior
- •Designed for scale, retries, and delivery guarantees
We take this seriously.
