@pascalbaljet sorry about the ping but I couldnt tag brady in here for some reason and I can see you updated his feature/notify-old-email branch. Any chance of getting this in? This is the only thing missing for me

You probably couldn't tag me because I haven't created an issue or commented on one before. I'm also no longer working at Protone Media.

Just realized I also implemented a feature in this branch to recover an account after their email address has been changed. I believe this needs some more testing, because of the risks it could bring if there's something wrong or not working.

I'm also hoping this will get merged soon 😁
