Founder’s Note

Hi All,

I created SenderStack because, like many of you, I was spending far too much time in my inbox—writing, replying, summarising, translating—when I really wanted to be building, creating, and connecting.

Email wasn’t just a tool anymore. It had become a time sink. And I knew there had to be a better way.

So, I set out to build something different: an AI-powered email assistant that actually feels like an assistant—smart, fast, and helpful. One that not only drafts and summarises emails, but also supports multilingual teams, analyses what’s working, and integrates smoothly into your daily workflow.

We built SenderStack for entrepreneurs, sales teams, freelancers, and global businesses—anyone who values clarity, speed, and good communication.

If you’ve ever felt buried by your inbox, I hope SenderStack gives you back not just time, but focus.

Thanks for being here. We’re honoured to support your work.

Martin Kamata, Founder
