Yes there is it’s called procrastination

Yes I realized this too late, after I had already used the private email adresses from proton pass everywhere.

My solution ( while not completely private but better than using the same one everywhere) Is to use my own firstname.lastname@domainicontroll.com for thing already linked to personal info and then set up custom domain for proton pass hidden emails to @fuckgoogle.otherdomain.com

Then if proton ever goes to shit I can still go to another email provider and all I have to do is move the domains. Yes it isn’t free but there is no such thing as a free lunch, self hosting isn’t free either and I don’t have the mental bandwidth to self host an email server right now.
