Hey @Caroline Nunes 

Thank you for reaching out to the Klaviyo Community for help! 

I have a few questions for you first. What integration are you using? Are you wanting to add their purchase information i.e. product image, name? Or were you wanting to add suggested products based on what they purchased?

 @Caroline Nunes Yes you can, but the amount of dynamic content that you can add to your transactional emails will depend on the configuration of your ecommerce integration with Klaviyo. Generally, with Shopify and Woocommerce you should be able to achieve that with ease.
