I do something similar with prepend.com and find it helpful for sorting. Also fun to see which domains sell my email and which dont (blacksocks.com hasn’t show up from anyone else in 20 years).

I use +, so username+domainname@email-vendor.com

Which is in the RFC, but yet the sheer amount of times I sign up for something. Like a bank, or a financial firm, get the confirmation e-mail, and then click "Verify your address"

And get HTTP500 as their SQL has kicked up a stink

> That's why I bought my email domain and use <domain_name>@hnrobert42.com. It helps to use a password manager.

Whenever there’s this discussion on HN, someone usually points out that can sometimes be a bother, especially when giving out the email in person, because people don’t really understand how email addresses works and ask “how did you get that email” or think you’re impersonating the service, or something similar.

I guess a solution might be to add the details sneakily. E.g. instead of linkedin@hnrobert42.com, saying robert_lkdn@hnrobert42.com
