Personally Address Email
The substitutions available for email are essentially the same whether the email is sent from an inbox or from a posting to a bulletin board. Note that the message saved in the bulletin board or in the sender's inbox will not have the fields replaced, the substitution occurs when the email is prepared.
The basic syntax is [$var] except with curly brackets. (I cannot use a curly bracket and a dollar sign in this explanation without getting a substitution, so I will use square brackets for many of the examples.)
If the email is being sent from a form, the fields from the form are placed in a variable called $fields.So you might refer to values such as [$fields.firstname] and [$fields.email] provided that the form included fields called first name and email.
Note: If a variable is incorrectly implemented, you will see a red error
message, requiring your message to be corrected. However, the error message and linenumber might not be helpful
in telling you which reference was incorrect.
Items sent in email have a variable $user that has values that change for each email recipient. Review the table below explaining how to implement variable for personalized messages.
