Built on proven, boring technology.
No exotic dependencies, no moving parts we can’t reason about. The kind of stack you want holding your email — fast, typed, and hard to surprise.
One typed language end to end — fewer seams, fewer surprises.
The dashboard and this site — fast, static where it can be.
A fast, fully-typed API. Boring in the best way.
Durable and relational. Jobs run on the same trusted store.
Open-tracking runs at the edge, close to your recipients.
Runs on Google’s infrastructure, auto-scaling and managed.
Two thin surfaces that meet you where you already work.
Powers AI auto-respond — bring your own key, you approve sends.
Choices you can stand behind at 3am.
Every piece here is widely used, well understood, and battle-tested by teams far larger than ours. When something breaks, the answer is a search away — not a spelunking expedition. That reliability is the whole point: your follow-ups have to fire whether or not anyone’s watching.
