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’m trying to separate mail accounts between stuff (online shopping, socials/casual, work, personal) to see how it goes. Most of them go through a single client anyway but at least I know which account I have to read right away and which I can skip for a day or two. I’m going with ProtonMail for personal (banking, health, etc.), infomaniak for general use, and gmail (sigh) for work
For sites that I don’t trust and some newsletters I use aliases with SimpleLogin.
