Indeed. I received 28 unwanted emails of this kind in January so far (just counted), which is a bit more than once per day, despite quite avidly unsubscribing from this kind of emails. This month I had to unsubscribe from ChatGPT and GitHub emails of this kind too, although I don’t recall opting in to them in the first place and neither of them spammed me until recently.

Dark pattern. They know you'd spot immediate abuse , so they delay until you are likely to have forgotten whether you opted in.
