I really wish email had a built-in aliases feature. Like, so you can create unlimited new addresses that just point to your normal inbox. That would help so much with spam, since you could just block individual aliases. I know some email providers have this feature, but usually it’s paid. Plus Addressing is also nice, but it does nothing to hide your “real” address. Also I’m disappointed that end-to-end encrypted email is basically never used by normal people.
