FeedbackExpress offers a wide range of smart tags that allow you to pull in information on each order. You can see more on smart tags here.
We have a smart tag set up specifically for Product Review campaigns: [#thank-you-for-feedback:#]
In order to use this tag, you would need to create a Product Review campaign and add it in it. Then, it will check if the customer has left seller feedback and thank them for doing so within the product review message.
This prevents you having to set up two separate campaigns to do the same thing and in turn, will hopefully help encourage customers to also leave a product review.
You can see the standard message below, but you can edit it if you want to have a different message. You will find the smart tag under "Buyer Related" section.
Standard Message: Thanks so much for leaving a positive feedback on Amazon for us. It's greatly appreciated.
Our youtube video will give more guidance:
Note: if you add this smart tag to your campaign but the buyer did not previously leave a seller feedback, then the sentence won't show at all.
