I can confirm this. I was frustrated at some points when I was on my early day with my news letter and AWS SES. I don't know why people spend time to register for my news letter, after reading through the archive. Yet, they chooese to mark email as spam even though we explicitly have an unsubscribe link and require double opt-in. For AWS SES, you have to maintain spam rate at <0.1%. And AWS has their own way to pick sample set of emails. So yeah, it's really important to manually unsubscribe people that won't read email. Don't even attempt to make a final email to ask them if they want to be remove because you risks another "mark as spam" click.
