I’ve had better experiences elsewhere, but this one was still decent enough for me to consider using again.
What I liked most is how easy it was to get started. The setup didn’t take long, and everything felt intuitive. There are a few small things that could be improved, but nothing that affects daily use.
Easy to send & receive encrypted emails
