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 Mailinator for most throw away emails. I still use my old Gmail for tax stuff, things related to bills and whatnot. My personal email is hosted on Posteo. My conversations with friends are the only thing I feel need to be kept from the 5 eyes.
