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?
I use addy.io to create aliases for different things, and then set up filters in Thunderbird to mark them as they come in so, for example, if I make an account at xyz.com and then I get a bunch of unrelated spam marked as coming from xyz.com, then I know they've been selling my info.
I probably have about a dozen or so aliases currently, but they're pretty loosely organized.
I also use addy but create an alias for everything. Even my wife has one!
I probably will end up with tons eventually, I haven't been doing it for too long and I don't sign up for many things lol
