I had the same experience and feeling.
I've also experienced this elsewhere. TIAA was essentially sending me marketing emails I couldn't unsubscribe from. My financial manager with sympathetic and communicated my frustration to the business, but I don't believe it lead to any changes. As a result I have marked my emails from TIAA as spam, which now means email is not a reliable source of information from them, and so I unsubscribed from all email communication and instead receive paper mail. Sad.
I can name others using this pattern. Very frustrating. It's a lot of work to sever these relationships. I guess they know this and so think they can get away with it.
