Hey @Yul ,
I’m unsure with Stamped. I’m guessing you are on Shopify? Probably one of my favorite review apps in Shopify is Judge Me. Through Judge Me you can pull in star reviews and also the review text itself. Worth checking out!

You may be able to use Make for this.
Make is a highly visual, no-code workflow automation solution with pre-built connectors for over 1,500 SaaS solutions including Stamped, Shopify and Klaviyo.
You could build a workflow that watches for new reviews in Stamped and then write them into the product block in Shopify.
Alternatively, you may be able to pull them into email templates in Klaviyo, again using Make.
Make has a Free(forever) tier for low usage levels - paid plans start at just $9/month.
There’s also a helpful Make Community if you have detailed questions.
