Suggested Solution

The email should include the Site ID for the site where the user is requesting the product to be added.

This is reproducible on Cloud: (yes)

Steps to Reproduce: 

• The user navigates to the Atlassian site (XXXXXX.atlassian.net).  
• They click on the "Your Apps" icon in the top left corner.  
• The user views the products under "Recommended for your team."  
• The user click on a product that is not currently available on the site.
• The user receives a message indicating that admin approval is required, along with a link to share with the admin.

The administrator receives an email : 

• The administrator is unaware of which site the user is requesting the product to be added to.

Workaround:

When the administrator clicks on "Try <product> for free they will be redirected to their site:https://admin.atlassian.com/s/<siteID>  From this site ID the administrator can find out to which site the user wants to add the product.
