NAB Australia does exactly the same thing. Unless I "load remote images" when I receive their emails, they'll start mailing letters saying that they switched me to paper statements as their emails are not going through. It also took me a bit to investigate as their emails were obviously coming through.

I'm in two minds on this - the bank does need to know that its communications are being received

But, they have no idea if the paper statements are making it to your desk, or if they are getting swiped from the letterbox (I'm in an apartment in Melbourne, and the snail mail is not reliable at all, mail is sometimes delivered to the wrong building, sometimes the wrong address entirely, it's also swiped by miscreants who have nothing better to do, and, in some cases, the pricks set the letter boxes on fire, taking all the mail with it)

If the bank really needed to know that its communications are being received, they would send them in a way that would reliably return this information (signature-confirmed postal mail). It's very unlikely that the bank actually needs to know this information.

CapitalOne balance alerts for a low-use credit card - they silently disabled the alerts because "I wasn't reading them". Because I have read notifications disabled and don't load remote resources.

Even if they truly believed I wasn't reading them, disabling them makes no sense to me. They certainly weren't bouncing and I wasn't reporting them as spam.

I dropped CapitalOne after that (not sure I moved to something better though...)

If NAB has an option to turn on plain text emails, that might help, since they obviously can't do tracking that way.
