A note from the founder

Email was invented over 50 years ago. Since then, computing has gone through several major shifts: the PC, the internet, smartphones, and now AI. But for many people, the basic email experience still feels the same: open your inbox, scan a long list of messages, decide what matters, write replies, and hope nothing important slips through the cracks.

There have been many attempts to reinvent it or replace it entirely, but email endures as one of the internet's most important communication primitives. It's open, universal, and independent; you can reach almost anyone in the world without needing to be on the same app or platform.

I think that's incredible.

But email too often feels like a burden. It still asks you to manually prioritize incoming messages, follow up at the right time, and keep track of what needs a response.

Fluxmail was started to make email feel calm, fast, and under control. It helps you see what needs your attention, act quickly, and trust that nothing important gets missed.

I believe your inbox should feel less like a list of messages and more like a really good personal assistant: one that understands what matters, helps you act on it, and then gets out of your way.

So you can get more done, with less stress.

Here's to better email.
