Should be all of them by now.
I got onto that around Jan '22.
With Bell Direct, the process was a little... indirect, lol.
I had to print off a Change of Email Address form,
fill out my old email address and put my new email address 'as above'.
I think this was just a makeshift solution at the time.
Having said that, I don't think I've ever received any emailed CHESS statements since!

I don't care about them, just didn't want them clogging up my post-box, lol.
