This was one of the unexpected perks of moving to FastMail, which has been an awesome experience so far. I'd highly recommend it. You can do something similar in Gmail with `name+label@gmail.com`, but a shocking number of sites ban valid characters from email addresses (intentionally?). That and a lot of clients have super annoying alias settings, so replying to such an email is a royal pain.
