Same experience, but a different perception. I’ve always found it to be a great conversation starter when I did this with my business domain. Of course, it’s mainly about spam control, but some people even felt flattered to have their own personal email address. Then there was that one time I tried to open a new bank account using bankname@mydomain - it ended up involving three levels of management. On the bright side, though, they now greet me by name whenever I walk into the building.

I think having a mail just seperately for bank can be good thing instead of having it on your own @mydomain I suppose?

Also can we have things like 2FA in banking apps? I am pretty sure...

Like my idea of thinking is to create a new proton account just for banking and doing the thing as in the article and not really ever linking the two of them or maybe even having a google account if proton causes any issue for my banks.
