I would have expected them to ask me to message them, in order to resolve the issue of not having access to my old email. Instead, they assume that I still have access to it, by simply contacting my email provider!
If I could do that, I wouldn’t have lost access to it through would I?
Is that an old person thing? I have one custom domain exclusively for my work email, and while I was at it I made one for my personal just because I could.
