Can you show me some advanced examples of email notification templates?

 

Templates use variables to automatically insert ticket information into emails. There are variables that will automatically provide the guest's name, the original question, etc... within the notification email.  

Email Notification Templates use the Mustache templating language. Most notification templates only need simple variables such as {{guest_name}} or {{ticket_subject}}, but Mustache also supports conditional content, loops, and comments.

 

Basic Variable Usage

Insert the value of a variable:

Hello {{guest_name}}

Example output:

Hello John Doe

 

Comments

Comments are ignored when the template is rendered.

{{! This comment will not appear in the email }}

Comments can be useful for documenting complex templates.

 

Conditional Content

Display content only when a variable has a value:

{{#ticket_note}}
A note was added to this ticket.
{{/ticket_note}}

If ticket_note contains content, the message will appear. If not, nothing will be displayed.

 

Inverted Conditions

Display content only when a variable i14s empty or missing:

{{^ticket_tags}}
No tags have been assigned.
{{/ticket_tags}}

This block will only appear when the ticket has no tags.

 

Working with Lists

Some variables contain multiple values. For example, ticket_tags may contain several tags.

You can loop through the list and display each item:

Tags:

{{#ticket_tags}}
- {{.}}
{{/ticket_tags}}

Example output:

Tags:

- billing
- account-access
- urgent

Within a loop, {{.}} refers to the current item.

 

HTML Content

Most variables should use double curly braces:

{{guest_name}}

Variables that may contain formatted content, links, or HTML should use triple curly braces:

{{{ticket_question}}}

Using triple curly braces allows HTML content to be rendered correctly in the notification email.

For example, if a ticket contains a link:

Page is <a href="https://example.org">available here</a>

Using:

{{{ticket_question}}}

will display a clickable link in the email.

Using:

{{ticket_question}}

will display the underlying HTML code instead.

 

Combining Conditions and Variables

Conditional blocks can be used to create more dynamic notifications.

Example:

Subject: {{ticket_subject}}

{{#ticket_note}}
A new note has been added:

{{{ticket_note}}}
{{/ticket_note}}

{{^ticket_note}}
No note was included with this update.
{{/ticket_note}}

This template displays different content depending on whether a note is present.
