You can create customized auto-response messages for valid Amazon orders based on the initial keyword that customers text in order to participate.

If you are using multiple keywords for your Amazon campaign, the auto-response message for valid Amazon orders does not need to be generic for all keywords. You can now create a unique response for each keyword in your Amazon Campaign.

Here's how it works:

• The customer text in the keyword.
• The customer receives an automated text response (prompting to text the Amazon Order ID).
• The customer replies back with the Amazon Order ID.
• The Amazon Order ID is validated and if it's valid and the Amazon Auto-Reply for the keyword is set, then the AR for the keyword is sent back.

IMPORTANT:

• The main keyword should be attached to the Amazon app (a.k.a amazon keyword).
• From the Amazon Auto-Reply Messages page, there is an option to 'Set Auto-Reply by Keyword' (only the Amazon keywords will be listed in the pop-up).
• When the Amazon keyword is removed from the app the Auto-Reply Message for the Keyword is deleted.
• Amazon Auto-Reply by keyword conflicts with the flow for the "Auto-Reply Messages Based on Amazon Order Status".
• If there is at least one active AR from "Auto-Reply Messages Based on Amazon Order Status" then the ARs for the "Valid Orders" case are deactivated (default & per keyword).
