What part of UNsubscribe is unclear?

Claudia Caldwell from claudiacaldwellketo.com and Keto Diet | Claudia Caldwell (@keto_with_claudia) may be marketed as part of the Health, Beauty & Well Being industry, but there is nothing well or healthy about the persistence with which they ignore any and all attempts to unsubscribe. Like an invasive virus they continue to send email after email with unhealthy vigour despite the fact that I have unsubscribed from them multiple times. In a moment of weakness I succumbed to the lure of a "free keto recipe book" some years ago. My primary gmail address has been bombarded at a steady rate to the point that the mailbox is almost full. After deleting every mail from them manually and reporting spam, it did not stop. As soon as I escalated my effort to get rid of the unwanted daily mails by unsubscribing, their emails suddenly infiltrated a secondary gmail address used for recovery purposes. I skipped reporting as spam on this mailbox and went for unsubscribe immediately. This afternoon I counted no less than 33 mails from them in my spam folder for both emails. I would strongly advise against clicking anything linked to this site and/or instagram page.
