The JSON used by the Message Center, that is, the source of information to be sent by email is a combination of information from different systems. They include information about the order from the Orders management and account information from the Account management.

When viewing the hostName variable in MessageCenter JSON, doubts may arise as to where this data is loaded from. No matter that the name of the variable is host, it bears the - unchangeable - name of the site created in the Accounts tab of the Account management.

In other words, the value inserted will not be loaded in the Hosts area, rather, as shown in the image above, the value registered under Nome da Loja will be loaded to the email template.
