Unbounce is a drag-and-drop builder that lets you create and publish your own landing pages without excessive codework. You can install Drift on these landing pages to engage your visitors just as you would on a more standard html-based webpage.
Your Drift account has a unique and personalized snippet that points to your organization's inbox. You'll want to make sure you use the code snippet located in your account.
Locating the Code Snippet
You'll find the javascript code snippet here. You can additionally find this code snipped by going to Settings > App Settings > Drift Widget > Install

Installing the Code Snippet with Unbounce
Once you have your code snippet from the instructions above, you'll want to proceed to Unbounce and follow these instructions for installing Custom Javascript with Unbounce.
Keep in mind, you’ll want Drift’s snippet installed in the head of your page.
Unbounce has configurable modal windows called Lightboxes, Lightboxes allow you to highlight important information like forms, instructions, and videos — while also helping you declutter your landing pages. If Drift is appearing in your Unbounce Lightboxes as well, make sure to exclude “lightbox” from your Playbook URL targeting in Drift. It should look something like this.

For further information on Playbook Targeting, check out our help doc here.
