Also, do you use disposable emails? What for?
I have a lot of emails made with simple login and I use the same one only for three websites. Then I get all emails forwarded to the same email, and an email for personal use (family, work, friends…) also forwarded to that one. So something like this:
o o o o personal
\ | / /
| /
| /
o
I have three domains with catchall. One personal, one thats not easily associated with me that is forwarded to my personal that I use for sites that don’t have to know who I am and one that is under a nick-name for FOSS stuff.
