I’ve worked in automated marketing for close to a decade now. Use your inbox’s report as spam function. It’ll damage their sender rep resulting in more of their emails automatically going to spam and will usually add you to their application’s system level unsubscribe list automatically. I usually do this if a company’s preference center requires me to log in to global unsubscribe.

I’ve found that changing my email address works better than unsubscribe sometimes. Just change it to a tagged address and set up a filter. Shields you against future sales as well.

All the Trump emails go rbos+fucktrump now. Probably a hundred a day. Unsubscribe did not work.

Also, Canadian. Incompetent jerks.

Just mark those as spam if you are using any big email providers. Causes much more headache for them and you don’t need to play their find the correct unsubscribe button games

That ship has sailed, but you have to sign up with a mail account that offers throw away addresses (like yahoo! mail or others). They just put the mails from all throwaways also into you main mailbox. If later you can’t ubsubscribe, you can just delete the throwaway. Only problem is, for replies you have to use the mail providers way (i.e. webmailer) so your client doesn’t reply with your main address. But I found it very rare I reply to mails from subscriptions.

Is this from Spain?

It sounds like what they are doing is clearly illegal and you probably could do a lot of people a favor by complaining to the authorities.

Generally for the eu: https://www.europarl.europa.eu/doceo/document/E-8-2017-003934-ASW_EN.html “If users receive unsolicited communications after having withdrawn consent, they can file a complaint with the national regulatory authority. In addition, they have the right to a judicial remedy before national courts.”
