Mailjet Email Marketing [mailjet_form_builder] Shortcode

The Mailjet Form Builder shortcode is a powerful tool in WordPress. It dynamically displays a Mailjet widget based on the user’s configuration. The shortcode uses ‘widget_id’ to identify the specific widget to display. If ‘widget_id’ is not defined, it defaults to the first widget id in the collection.

Shortcode: [mailjet_form_builder]


Here is a list of all possible mailjet_form_builder shortcode parameters and attributes:

  • widget_id – identifies the specific form widget to display

Examples and Usage

Basic example – A simple shortcode to display the first Mailjet form builder widget configured by the user.

[mailjet_form_builder /]

Advanced examples

Using the shortcode to display a specific Mailjet form builder widget by referencing its ID. This will display the widget associated with the given ‘widget_id’.

[mailjet_form_builder widget_id=2 /]
