Tutanota is the secure email service, built in Germany. Use encrypted emails on all devices with our open source email client, mobile apps & desktop clients.

I recently discovered Tutanota email service and it seems like a great option for people worried about privacy but I don’t know how to be sure.

Does anyone have anything to say about them?

Know about their track record?
