That is a reasonable strategy, but I need to figure out a way to delete SPAM emails only.

I still need transactional emails to go through, unless I change pharmacies, which isn't impossible to do, but has downsides that may be more painful than having to "Mark As Spam" a couple of times a week.

With the right filter, you could have the best of both worlds. Assuming that the company spamming you has a set format or some standard text in their spam that isn't in their other emails, you could filter based on that.

Yes, I have to figure out the right pattern and block that.
