Templating allows you to efficiently personalize messages for users. You can insert any User Attribute into a message--for example, their name or status--and the current value of the attribute for each user will be displayed when the user receives the message. Templating can be used in the title and body of In-App Messages and in Push Notifications.

Note: When personalizing a Lifecycle Optimizer push notification, use Zephyr.

Templates employ the use of double curly braces ('{{', '}}') to signify when an attribute is used.

Here's a simple example of how to greet a user by name:

Input: "Hello, {{ custom.user_first_name }}!"

This simple template would look for a user attribute with the key 'user_first_name' and then on a user-by-user basis, would replace it with the value (their name). This includes the double curly braces.

Output: "Hello, Sam!"

If they don't have a value set, then you can use a default value.

Input: "Hello {{ custom.first_name | default:'there'}}!"

Output:"Hello there!"

This also applies to text, numbers and dates too.

Input: "Hey {{ custom.first_name | default:'there'}}. We see you've purchased {{custom.total_purchases}} products so far, with the latest being {{custom.latest_purchased}}. How are you finding them? Please fill out [this survey](www.mycompany.com/survey) to tell us more!</span>

Output: "Hey Sam. We see you've purchased 9 products so far, with the latest being 5/5/2015. How are you finding them? Please fill out this survey to tell us more!"

For in-app messages, we support even more of the Liquid Templating Language, so there's many more advanced techniques you can use such as conditional text, math, and iteration.
