Many One B.V.

Many One is a software development venture helping people and businesses make their email systems faster, safer, and more reliable.

Offering both free and paid services focused on email security and infrastructure, so whether you’re running your own setup or using a SaaS platform, we can help you build, upgrade, or fine-tune it.

With over 20 years of experience in commercial and corporate email security, we’ve seen just about everything that can go wrong with mail flow and how to fix it. I also build and maintain a few open-source tools, like our very own Robin MTA and Tester, which help audit, secure, and improve your email stack.

If your mail isn’t flowing, or you just want to make your system more solid and secure, get in touch. We’re always happy to help.
