For many people, email is just a tool. For Robert Heide, this is also true, but with a deeper understanding: As a developer he knows that emails are like postcards – everyone who gets their hands on them can read them. And that is something he did not want to accept. Robert has been using Tuta for almost a decade now, long before digital privacy became a mainstream topic. Today, he is building a startup of his own, fully relying on European technologies. As digital sovereignty in Europe becomes more and more important, even the German tech site Heise reported on Robert’s startup hank – and that’s also how we first met our long-time user! We talked to Robert about why he switched from Gmail back then, what he likes about Tuta today, and which features are crucial in his day-to-day life.
