Hello, world: why eusend has a blog
A place for engineering notes from running self-hosted email infrastructure in the EU — the wins and the messy parts.

SivertFounder / Coffee DrinkerBuilding eusend — email infrastructure where your email data never leaves the EU.
eusend is an email API built on a premise most of the industry finds inconvenient: that "your data stays in the EU" should be an architectural fact, not a marketing sentence. We run our own mail servers on European hardware, under European law.
Running it yourself generates a lot of hard-won knowledge: IP warming schedules, bounce classification, MTA shaping policies, what actually gets you onto a blocklist and what gets you off one. Most of it isn't secret - it's just rarely written down by the people doing it.
That's what this blog is for:
- Engineering notes - deliverability, self-hosting, and the security work behind an email platform
- Product updates - what shipped and why
- The messy parts - honest write-ups when things break and what we changed
Signups are open — create an account and send your first email in minutes. If you're building something that needs email and you'd rather it stayed in Europe, come say Hei.
