I have it setup in Proton where anything sent my domain goes to my inbox. So I write it down to keep track, just for my own knowledge of what I used (but it’s not technically needed). The nice thing is I don’t have to set anything up before I start to use it. I can just type sitename@mydomain.io and it shows up in my inbox, which has made it very low maintenance. I tried to setup aliases in the past and it became more work than I wanted.

The idea was if I got spam, I’d know who not to trust in the future, and could easily send anything to that address to spam/trash.

I use a password manager as well, and have all the accounts tagged in there as well. The spreadsheet was basically a backup, and for if I gave an email address out that wasn’t actually tied to an account I’d have a password for.
