Of course, I got a new message from them yesterday because they've added a dozen different lists since then and automatically opted everyone into them.
I paid some company to do my email.
I email 3 times per year and get 'spam' warnings from AWS every time despite everyone subscribing through a: "SUBSCRIBE TO OUR NEWSLETTER"
No bait, just an email field and submit.
I wonder if its your type that makes it so I have to be Amazon for forgiveness. Or at least that is how it used to be, now I sell addicting clicking casino games. No emails needed. I make way more money than back when I was giving away free content via email.
The new requirement specifically sidesteps this, by making it possible for the email client to send a POST request directly. No need to visit the website at all; just click a button in the email client. In Gmail, senders that have this implemented now have a big blue UNSUBSCRIBE button next to their email address at the top of the message.
