This takes advantage of new features in Amazon's Marketplace API (MAPI).
Note: the Review Request Email Rule does not count against your overall email count when calculating overages. MBS allows you to use this Rule at no extra charge.
Review Request is offered by Amazon as an option within each order in Seller Central. You can go into any order in Seller Central and click the button:
Amazon then sends the review request to the customer. Convenient, but very manually intensive.
SellerMail allows you to automate this function.
You'll see the option to create a Review Request email rule under SellerMail:
On that page click the "Add Rule" button and you get the interface for adding a Review Request email:
1) Set the desired criteria to send a Review Request email. Click the question mark (?) by each item for more info.
2) Select which products or groups of products the rule will apply to.
Click "Add" and your rule is added to the list.
Review Requests email rules become an automatic trigger for Amazon's Review Request feature.
Note: there's a time window in which the Review Request can be used. Make sure you set your delay (Send this email __ days) to fall within that window.
Recommended best practice is 7 to 9 days, though anything in that window works. Just be aware Amazon will strictly adhere to that span of days.
Note Also: unlike other Email Rules, there is no message composition body for this. Amazon sends a standard email, we're just triggering it based on the criteria you set.
Here's a sample of what the Amazon email can look like, and what the customer sees:
