Advice for First Creator Connections Campaign

I am getting ready to launch its first Amazon Creator Connections campaign, I’m hoping to tap into some advice and best practices.

I’m interested in attracting creators showcasing the products in daily routines wear our products, unboxing and try-on videos (not deals or promo ones). I want to create a campaign brief that attracts creators who can authentically showcase the quality and comfort of our products.

I’d love to get your perspective on a couple of things:

• What kind of information in a campaign brief tend to be most effective in catching your attention to apply?
• What commission rate would be considered attractive and competitive? 10% is minimum but going 15% and over is really stretching it since we also spend on PPC as well. Margins are so thin on Amazon already….
• Samples. I realize we have to send some out to good creators. But the item is not cheap, and I anticipate we’ll get lots of request. Any advice for a reasonable way for us to balance this?

I would really appreciate any advice and tips on other sellers who have tried CC already.
Thank you!
