Unosend raises $250K pre-seed led by House of Summary.

One API. Infinite Emails. Now with $250K to prove it.

Today, I'm excited to share that Unosend has raised $250K in pre-seed funding, led by House of Summary.

This one feels personal for our small, stubborn team. We started Unosend because, as builders, we kept running into the same problem: email infrastructure that was slow, fragile, overpriced, or clearly not designed with developers in mind. So we decided to build what we always wished existed, fast, reliable, affordable, and developer-first.

This funding is a real vote of confidence in that mission. More importantly, it gives us the runway to ship faster, keep reliability obsessive, and make email something you never have to think about again.

Why We're Building Unosend

Email is one of the oldest protocols on the internet, yet sending transactional emails reliably in 2026 is still unnecessarily painful. Developers deal with poor documentation, unpredictable pricing, rate limits that don't scale, and deliverability that feels like a black box.

We started Unosend because we believed it could be better:

• One simple API — Send emails with a single HTTP request or SMTP
• Transparent pricing — Credit-based, starting at $4 per 10K emails with no subscriptions
• Reliable delivery — Powered by our own dedicated sending infrastructure for high deliverability
• Global reach — Multi-region infrastructure across Asia, Europe, and beyond
• Developer experience — Clean SDKs, great docs, and an API that just works

What This Funding Means

With this $250K, we're doubling down on:

Infrastructure

We run our own dedicated email delivery infrastructure with per-domain DKIM signing and high deliverability. This funding lets us improve our product and scale.

Product

We're doubling down on what developers actually need — fast, reliable transactional email delivery, deep delivery logs, and a powerful dashboard to monitor everything.

Team

We're hiring engineers who are passionate about building reliable infrastructure at scale. If that sounds like you, reach out.

About House of Summary

We're grateful to have House of Summary lead this round. They understood our vision from day one — that email infrastructure deserves a modern, developer-first approach. Their support goes beyond capital; their network and operational expertise have been invaluable as we scale.

A special thank you to Aryan Khuman, CEO of House of Summary, for believing in Unosend early and championing our mission. Your conviction in what we're building gave us the confidence to move fast and think big. We wouldn't be here without your support.

What's Next

We're just getting started. Here's what's on our roadmap:

• More global nodes — Lower latency for developers everywhere
• Advanced analytics — Deep deliverability insights and reputation monitoring
• Enterprise features — Dedicated IPs, custom DKIM, SLA guarantees
• Open-source SDKs — Node.js, Python, Go, and more

Our goal is simple: one platform for all your email messaging with a single API key.
