Hi there,
I’m working with WooCommerce multi vendors site.

So the scenario is that the visitor can click “Contact Seller” button on the site and it will open the New Message form and set the “To” field automatically based on the product author.

My question is :
Is there a way to append data to the message body?
I have created the function to collect the selected product data (like images, title, price, etc), now I need to know if there is any hook/action to append it into the message body.

Thank you in advance!
