Using Template Parameters in Broadcast

Body Parameters

If your template contains variables in the message body (e.g. Hi {{1}}), you will see a BODY parameter field.

How to use:

1. Locate the parameter field under Template Parameters → BODY.

2. Enter the value you want to replace the variable.

3. The preview on the right will update automatically.

Example:

• Template: Hi {{1}}, check out our promotion

• Input: John

• Final message: Hi John, check out our promotion

Using contact data (dynamic values): You can personalize messages by inserting custom fields:

• Format: {{customFields.fieldName}}

• Example: {{customFields.firstName}}

Each recipient will receive a message with their own data.
