Before you can send a Landing Page message, you need to create a template in Messaging Studio.
We have three types of template you can use:
Text : a simple text message templates that can be enhanced with weblinks and pdf attachments
Image or Video: similar to Text but you can add an image or video to the message
Graphics, Text and Buttons: the most complex and visual, with images and call to action buttons
First, click on Create Template from the menu on the left side, your next screen will look like this.
Select which template you want to use and your ready to start creating.
