Well I’m from Europe. Being added to marketing mails without my explicit consent is illegal.

It’s funny because I have a GDPR complaint against a big online service that added me to their marketing list after using their online contact form to get some information. I thought it was a simple complaint but a few months later I got a legal document outlining all of the infractions they made and that there’s now a case open against this company.

If you signed up for their mails willingly that’s a totally different story of course.
