Searched for this for a while, but nothing useful so far, potentially a bug.
I am trying to change the template variable `%{site_domain_name}` to `%{site_title}` in the subject using the Customize → Email Templates interface, so that users see the name of the community instead of the temporary domain I am using in the invite emails. I see the following error:
> **translation missing: en.admin\_js.admin.customize.email\_templates.subject** : The following interpolation key(s) are invalid: “site\_title”
The same happens with `site_name`:
> **translation missing: en.admin\_js.admin.customize.email\_templates.subject** : The following interpolation key(s) are invalid: “site\_name”
Could someone suggest a solution?

You can’t arbitrarily add new text substitutions, that is not how the code works.
