I’ve been reading upon improve security and privacy. I was wondering how many mail addresses you should have. Is it one per social media, one for everything finance, … Next to this, are the mail addresses you use aliases or actual mail addresses and do you create them on outlook, proton or self host the mail server?
Depends on your threat modeling.
I have an address to register in irrelevant sites and the provider is also irrelevant.
I have an address for important use (utilities’ bills, government stuff, friends), currently tuta.
I also have an alias there for occasional registrations.
I’d try proton (has an .onion site) but they force you to supply a phone number or email address on registration, which for me defeats the purpose. They also leak a lot of links to clearnet.
Self-hosting has become increasingly hard but I haven’t tried it.
