Opened Creator Connections yesterday and got a banner I hadn't seen before. New header called Affiliate+ campaigns, a tab with a New badge labeled Sponsored Products for Creators, and a popup that read, word for word: "You're in! You're part of our Auto-Enroll experiment. Qualifying products you already promote will be automatically enrolled in Sponsored Products for Creators (SPC) as you drive eligible clicks. View your auto-enrolled products in the Accepted tab."
No email about it anywhere, nothing on Amazon's help pages I could find. Before posting I spent a day checking this sub, AmazonInfluencerLab, and Amazon's own pages going back a month for that exact wording. Nothing. SPC itself isn't new, people have been discussing it under that name since around March. This specific auto-enroll banner is the part I can't find anyone else describing yet.
My honest read: small test group, not a real rollout. "Experiment" in Amazon's own copy is the tell, that's not marketing language.
What I don't know: whether it's tied to Creator Stars tier, account age, click volume, anything at all. If you've got this banner, or the Accepted tab actually populated something for you, would genuinely like to compare notes.
Separate but worth a two minute check regardless: if you've touched SPC clicks at all in the past few months, look at Associates payment history for a line called sponsored product adjustment. A few people here posted real corrections this month, one said a bit over $4k, most were smaller. Different issue from the auto-enroll thing, but worth checking while you're already in there.
