One API. Infinite Emails. Now with $250K to prove it.
Today, we're excited to announce that Unosend has raised $250K in pre-seed funding, led by House of Summary.
This is a milestone for our small but determined team. We set out to build the email infrastructure we always wished existed — fast, reliable, affordable, and built for developers first. This funding validates that vision and gives us the runway to execute on it.
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 — Starting at $0 for 5,000 emails/month, scaling predictably
- ●Own infrastructure — We run our own mail servers, giving us full control over 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're expanding our global mail server network. We own and operate our own infrastructure with per-domain DKIM signing and full control over deliverability. This funding lets us add more nodes and improve redundancy.
Product
We're building features developers actually need — broadcasts for marketing emails, contact management, audience segmentation, SMS and WhatsApp messaging, email validation, 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:
- ●SMS API — Send transactional SMS globally with the same simple API you use for email
- ●WhatsApp Business API — Reach customers on WhatsApp with template and chat messages
- ●More global nodes — Lower latency for developers everywhere
- ●Advanced analytics — Deep deliverability insights and reputation monitoring
- ●Broadcasts — Send marketing emails and newsletters to your audiences at scale
- ●Contact management — Audiences, segmentation, and suppression lists built in
- ●Email validation — Verify email addresses before sending to protect your sender reputation
- ●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 messaging — email, SMS, and WhatsApp — with a single API key.
