Telligent Evolution uses templates to send system emails or notifications to community users about ongoing activity in Telligent Evolution, such as friendship requests and approvals, new accounts, password requests and changes and more.
The email templates are contained in the [Telligent Evolution root folder] / Languages /[Language Key] /emails/ folder.
You can modify the email templates to better suit your community's branding. Because the email templates are part of the Telligent Evolution language pack, you can define the email templates in multiple languages.
See the Developer documentation for a list of templates and tokens available to each template.
