Train-Up! makes it easy to give users feedback on their test results. Because of this, it also includes a bulk-action emailer to help you quickly and easily send out a notification to trainees that their test results are now available.
The shortcodes available in the emailer correspond directly to the fields that a WordPress user has and can be used in the body or subject line.
For example:
[known_user]
Dear [first_name]
[/known_user]
[!known_user]
Hiya
[/!known_user]
