Merge fields in the WYSIWYG editor

You can add merge fields, conditionals, and looping fields in the WYSIWYG editor.

A merge field is a variable in your message or template that you want to populate with a personalized value for each member of the audience. Merge fields use Handlebars syntax — {{merge_field}}. When you create a merge field, you set its Field Logic, which determines both how you use the field and the options you have when you use the field in a message:

Merge fields, conditionals, and looping fields make it easier to take advantage of Dynamic ContentVariable message content using Handlebars syntax that you populate at send time. Use dynamic content to personalize messages for each member of your audience. . Merge fields are not supported for Email Preference CentersA page where users can manage their opt-in statuses for the subscription lists in your project. Preference centers are presented within your app or website, or as an Airship-hosted web page. .

 Tip

You can also take advantage of looping (#each), conditional (#if), and other advanced HandlebarsHandlebars is Airship’s templating language for personalization. Handlebars expressions use double curly braces wrapped around a content template, ranging from a simple variable, e.g., {{first_name}} to complex evaluations of personalization data. within HTML content to show or repeat text. However, you cannot apply conditional or looping logic to block-level elements in your layout without adding merge fields to your layout.

Creating and editing merge fields

In the WYSIWYG editor:

  1. Click Merge fields.

  2. Click Create field to add a new field or   to edit an existing field.

  3. Enter a Field Name. This is the friendly name for this merge field that you’ll see in the editor.

  4. Enter the Key Path. This is the path to the variable that you want to use.

  5. Select the merge Field Logic.

  6. Click Save.

When you’re done creating merge fields, click Done   to return to the WYSIWYG editor.

Using merge fields

The way you use a merge field depends on its logic: None, Conditional, or Loop.

You can insert merge fields with Field Logic set to None into any Text content element in the WYSIWYG editor. Airship adds your merge field with the correct syntax in your text.

  1. Select the Text content element that you want to add a merge field to, and a toolbar will appear.

  2. Click Merge Tags from the toolbar, and select a merge field.


Merge fields with Field Logic set to Conditional and Loop apply to a row. You use the merge field to determine whether you want to show, hide, or repeat the entire Text content element.

While conditions apply at the row level, you can still use merge fields within your conditional block. If you want to use a field both as a block-level condition and as a value within a block, you should save two merge fields: one to represent the conditional usage of the field, and one with Field Logic set to None.

When you apply a looping merge field to a content block, you can reference the current instance of the loop with the this context. For example, if looping through an array of products in your audience’s shopping cart, you might reference the price for each product in the loop with {{this.price}}.

  1. Select the row you want to apply conditional or looping logic to and click  .

  2. Select the merge field that you want to apply, then select from the available options.

    For conditional merge fields:

    • Show if condition is false — Displays the block if the field does not exist, is empty, or is null.
    • Show if condition is true — Displays the block if the field exists and is not an empty string or null value.

    For looping merge fields:

    • Repeat for each — Repeats the block for each item in an array.
    • Show if there are none — Displays the block if the key path is empty or does not exist.
    • Show if there are any — Displays the block if the key path exists and has at least one item in the array.

  3. Click Select.
