I meant I run it.

But to answer your question, it uses subaddressing really well. When you give your email to a company, you add a label to the address just for that company, then all of their emails go in that label. You can easily toggle things like notifications, mark as read, and show in aggbox (our version of the inbox, since there isn’t really an inbox when everything is sorted already). Then if that company leaks your email, you can block that label.

You can also set up screening labels that are meant for real people, then any new senders get screened to make sure they’re human before you get their mail.
