No more spam from IEEE

IEEE was sending so much unwanted spam that I had to disable all communications from them via user account settings. After logging in to their portal, went to IEEE Account → Profile → Communication Preferences, where it was possible to select: “Please remove me from IEEE communications not required legally or for the fulfillment of services.”

After that IEEE asked for confirmation if I really want to disable all of their spammy emails, to what I answered “Of course!”. And hopefully their constant nonsense emails will stop arriving, as those were completely unwanted ~99% of the time.
