Protonmail is an encrypted email service. Which means that they cannot access your emails (unlike Gmail/google). I know it's not directly crypto related but I definitely recommend that if you're into crypto you should check it out. I heard about it awhile ago and switched all of my crypto accounts to my proton email account. Even if you don't want to use it, you should at least create a separate email address for your crypto accounts. Do not give your crypto email address to anyone and you should be well protected against being a target of a hack.
