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 use mailbox.org with my own domain and set up a catch-all so that all mails arrive in a single inbox. When I have to sign up somewhere I usually use their domain as the local part, e.g. example.org@mydomain.tld. That way I can easily identify who fucked up and can simply block all mails with that recipient.
