Unosend

Join the team

We're building modern email infrastructure for developers. Remote-first, high-impact, early-stage.

The inbox is broken. We're trying to change that.

Every day, billions of emails fail silently. They land in spam, bounce without reason, or never leave the queue. Developers are stuck duct-taping together APIs that weren't built for them, paying more for less, fighting deliverability like it's a black box.

We think that's broken. Email is the backbone of the internet. It deserves infrastructure that's fast, transparent, and built with the same care developers put into their own products.

That's why we're building Unosend. Our own mail servers. Our own IP reputation. Our own delivery engine. We're working every day to land your emails where they belong: the inbox. No middlemen. No abstraction layers. Just honest infrastructure, getting better with every send.

We're a small team, early-stage, and intentionally so. Every person here shapes the product, the culture, and the direction. There are no spectators. Only builders trying to make email work the way it should.

If you care about getting the details right. If you'd rather ship something real than sit in a meeting about it. If you believe developer tools should be beautiful and honest, we want to hear from you.

How we build

Unosend is built on a set of principles that guide every decision, from infrastructure to pixels. Here's what drives us.

01Own the stackWe run our own mail servers, our own IPs, our own delivery engine. No hiding behind third parties.
02Deliver to the inboxDeliverability is not a feature. It's the product. Every decision starts here.
03Ship, then polishGet it in front of users fast. Iterate from real feedback, not assumptions.
04Sweat the detailsThe small things compound. A fast API, a clean dashboard, a clear error message. They all matter.
05Be transparentNo black boxes. Users see what's happening with their emails. Teammates see the full picture.
06Stay leanSmall team, big output. We hire carefully and trust people to own their work.
07Build for developersDevelopers are our users. If the API isn't clean and the docs aren't great, we haven't shipped.
08Think long-termBuild infrastructure that lasts. Don't take shortcuts that create tomorrow's tech debt.
Fully remoteWork from anywhere. The best ideas don't need an office.
