In e-commerce I've noticed that customers that request to be removed from the mailinglist and/or to have their info/account be deleted often forget about ever using the site. Then a few months later they order something and sign up for the newsletter again. When they receive their "first" newsletter they recognize the style and remember that they requested it to be cancelled, which leads to many angry emails and spam reports.

An order form with no pre-selected "join newsletter" option doesn't seem to mitigate this problem. The obvious soloution is to save the customer's email in the mailinglist as unsubscribed, but afaik that's not legal if they request an account deletion.

I'm sure it depends on jurisdiction but that would presumably be saving PII after a removal request.

I find the tabs on my personal Gmail help a lot. Most of the form stuff lands in Promotions or Updates which I glance at now and then. Occasionally there's something I'm actually interested in. I used to keep a separate email for orders and the like but over time I found that just became a black hole that I never looked at.

Saving a SHA-256 of the email address seems like a perfect solution to this problem.

My favorite problem are people who go “Never email me again about anything” then a few months later complain “Why didn’t you tell me about the new version?”
