How can I request sellers to leave comments in the comment section?

I am looking for insight on trying to get more reviews from verified purchases. I send out ONE request 7 days after purchase. From everything I read it indicates Amazon will not allow me to send a 2nd request or contact the customer. Yet, on my personal Amazon account I purchased an item from another buyer and they send me direct emails from Amazon weekly asking for a review of the item. This is a chinese seller that started in 2021. Am I missing something? How can they keep emailing me for a review request yet I am not allowed. Any insight would be greatly appreciated.

Hey everyone, new seller here! 👋 I've noticed that many products on Amazon have thousands of ratings but far fewer written reviews. It makes sense—leaving a quick star rating should be much easier than writing a full review.

But here's what I don't get: How do buyers leave just a rating without typing a review? 🤔 When I check my own orders as a buyer, I only see options to write a product review, seller review, or leave feedback—but no option to simply tap the stars and submit a rating.

Is this an automatic feature? Or is there a way to enable quick ratings for my products? Or am I at a disadvantage because I'm a new seller and Amazon no longer offers the option to just leave a rating. Would really appreciate any insights—thanks in advance!
