At this stage just expect that every accounts will get leaked or rooted, it's a matter of when, not if... Use varying email `plus addressing` (john+am2604@foo.com), varying passwords or passkey and 2FA on anything remotely important (use of your identity, not just financials). |

It may keep out the bottom x% of spammers/hackers but it doesn't do much for the increasingly sophisticated scams that are appearing.
If the bit before the + ends up in your inbox anyway then it'll just get stripped off and used. Spammers seeing this kind of thing across several breach dumps:
bob+trello@example.com, bob+spotify@example.com, bob+chase@example.com
and will leverage that to target spam at you for other sites, or just email bob@example.com as there's a good chance that'll get through.
Years ago I did a test with my own domain where I created who unique aliases with plus addresses, e.g. steve.smith+iawer@example.com, bob.jones+wpoqe@example.com
It didn't take long for emails to start arriving to steve.smith@example.com and bob.jones@example.com even though that email address had never been used anywhere ever before.
As others have said, you're better off just creating unique emails with `pwgen -s 16` such as wmR5pNhGI8yidU7N@example.com and storing that in your password manager alongside a similarly random password. (Yes, this is roughly what those unique email address services provide.)
Also many services/sites/providers simply assume the username is immutable. $DEITY forbid you might have to change your email address at some point in the future.
