If you are sending out emails requesting people to review your product on Amazon, there is a way to structure the link that will take them directly to the review section instead of to the product page.
The URL in your link should look like this: https://www.amazon.com/review/create-review?asin=B015EDLTWU
Where the ASIN is correct for the product you want people to review. So this link should take you to a page to review the Burley Bee Child Carrier.
Oddly, this seems to work even if the person hasn’t purchased the product!
