Once you complete designing your app template, you can test your design.
1. Click the Test Your Design button at the top of the page.

2. Test your design using one of the options: Live Preview or Test Message.
You can scan the QR code and close the modal from the top right after your device opens the app, and then you can preview your design. Alternatively, you can send a test message to your registered test devices to preview it.

Once you test your design and make sure it works as expected, you can save this step to proceed to the next step to segment your target audience.
