I have the choice between Natnet mail and Gmail and choose Gmail. It is simply better and has many more options to manage it all, IMHO. If some evil person wants to access your mail they will likely get it anyway. However, Gmail now has 2 factor authentication, so it is almost impossible to hack when you use that.
This is a good point. If a government agency wants your email, I'm sure they could just as easily force a hosting company to give it to them as they could Google.
