> I don't think your definition of spam matches the one that I understand it to mean. Spam is random email from someone you have not had contact with before firing messages to every address they can find anywhere on the web, the dark web, etc. Or if you ask not to be added to a mailing list and are added anyway. They often use fraudulent tricks to try to get the email through filters, such as fake from addresses.
I would disagree with that definition, and wikipedia and multiple dictionaries appear to agree with me; it doesn't matter how many dark patterns the company uses or whether they (claim to) let you opt out after the fact, if the message is unwelcome, it's spam.
