I have a seperate e-mail adress just for subscriptions, shopping and such. That way data will be useless if companies happen to leak data, plus you can ignore all the spam and ads (cause lets be real they still get into your normale inbox somehow). Also, if I open my normal e-mail only important stuff will show op and the chance of overlooking it due to it being mountained by random mails. If there is any important subscription or thing I'll use my personal one of course, but this is def a rec. Out of sight out of mind.
