Ugh same. My first name is very common, last name moderately uncommon. I've gotten loads of stuff. Various quotes and invoices (vet, mechanic, window installation), invitations to child care groups, family gathering invitations (that one I think was the person writing the email address, not the person with my name).
Most of the time I just immediately unsubscribe or block or whatever and move on, but there's some (like the child care group) I had to reach out to because that could be potentially dangerous.
Get your own email right, people! It shouldn't be my responsibility to manage your email. Some of that shit includes your home address too.
I do agree that's a particular case that can't be solved by a password manager. But it's all the more reason to use one elsewhere to reduce how many you need to remember.
I have to remember only 3 secure passwords. My personal computer, my work account, and my password manager. Those are the only three I have to type in manually. And because they're secure and unique, for stupid work password change requirements I just increment the last character.
