The content of messages can be customized using the template tag library. Each template tag should be enclosed in a [% %] pair. Where a tag requires a qualifier value, the value should be attached with a colon.
For example, the following extract shows a member’s name being inserted into a greeting:
Hello [% member:first_name %] [% member:last_name %], Welcome to the "Exciting Onions" mailing list, where you can be kept up to date on all the latest onion-related news ...
Some tags also accept additional key/value pairs to control their behavior. For example, adding a default value to a member field:
Hello [% member:first_name default="Friend" %]
...or specifying the link text for a trackable link:
Please visit [% link:http://fancyonions.com/home name="our website" %]
