Thanks for the interest in my plugin!
In the early versions of the plugin, it sent review invitations with several links to different product pages just as you described. However, this approach didn’t work very well because submission of reviews in this way required high efforts from customers. They had to visit a different page for each product link in the email. Next, they had to login to WooCommerce store but most of the customers didn’t know their passwords, so they had to reset them. Also, most of WordPress sites don’t load very fast and not optimized for phones, so it led to poor user experience for reviewers. As a result, the number of customers submitting reviews was very low.
To solve these problems, I decided to introduce an aggregated review form that includes all products from an order on a single page. The URL of this form is only known to the customer who made the order, so no additional logins are required. This form is optimized for mobile devices because many customers review their purchases from phones. Also, it is hosted on Amazon servers with CDN to ensure blazing fast loading speed.
The time showed that the new approach to collecting reviews with the aggregated review form works much better than the old one. So, currently this is how the plugin works.
I hope it answers your question!
