Amazon has strict guidelines about the types of emails you can send to buyers. Email you send to buyers cannot contain any of the following:
Links to any website
Seller logos if they contain or display a link to the seller's website
Any marketing message or promotion
Any promotions for additional products or referrals to third-party products or promotions
Because of this, we only recommend setting up the Amazon Marketplace integration if you need to send post-purchase instructions or information about someone's order to Amazon buyers.
