I am geeky enough to use PGP or S/MIME if they had the option, but I can definitely see how vendors would see this as too fringe with retail customers. I would not like the typical "secure email" which is nothing more than a volatile link back into yet another website.
It'd be great if there's a unified API for all financial institutes to provide sensitive info (statements, tax forms etc.) and you just need to run a software tool to download them once in a while or when you need it.
I want the PDF (or CSV) emailed to me as an attachment because that's the workflow that doesn't suck.
Everything else sucks in one way or another, and much of it is security theater.
Although what I would really like, and think is long overdue, is an extension to email that normalises encryption and sender verification. It's ridiculous that email can be spoofed like that. (The same is even more true for phone numbers.)

It's true that email isn't quite as insecure as it used to be (it was once compared to shouting your message at someone and expecting them to shout it in the right direction until it reached the intended recipient), but there are still many things missing compared to other forms of direct messaging, and there's good reason why many people and organisations don't want it used to send sensitive information.
I have a laundry list of other issues I'd like fixed in email, but I'd be happy just to get end to end encryption and sender verification.
