Email strategy with aliasing and custom domains, tips are welcome

My setup is I self-host SimpleLogin (an open source email alias tool), you can also pay $36/yr for it too

But it gives you a chrome extension, iOS app, etc. and all the emails would forward to your main. It’s nice because you would have an email that’s “facebook.3sdfj@simplelogin.io

You can have a separate alias for each service (which is what I do) and it helps me figure out which services are sharing my email broadly and where is my spam coming from (Ticketmaster was a culprit, a surprising one was MBA programs, they sell your application email to other universities)
