To test the links in a campaign follow these steps:
Step 1: Copy the url in the Action URL box in the editing tools.
Step 2: Paste the link into your browser. You can ensure your images are also properly located by pasting the image URL into your browser as well.
Another way that you can corroborate the links is to:
Step 1: Click the Actions button located on the left corner of the template’s builder and select the option Preview.
This button will allow you to click all the images and buttons like the end user and will redirect you to the pages linked so you can confirm the work.
