Hello. Correct me if I am wrong…but it looks like you want the list of email shortcodes? We currently don’t have all the of the vars available for the email templates. However, you can look for things added to the $data array of the email class for each email template:

You can also add your own fields by using the pmpro_email_data filter. So something like this would add the current date to the template.

Let us know if this helps. Thanks
