Create memorable campaign name that you can distinguish later
Now you see random Exit-Intent popup set by default. So let's get started:
Set the Goal - you can go without it to be honest. It depends of your desire to make it more results-oriented from collecting emails to just viewing of content. In order to learn more about how to set goals for your campaigns, I would like to recommend you to read a separate guide on how to set goals and why do you need that;
Design your campaign add text message, change colours, patterns. Add timer, email or phone collecting mails.
In Behaviour section you may change how it triggers before someone trying to exit or while scrolling your page
Schedule campaign in Settings section;
Choose devices on which your campaigns should be shown, put your page's URL and include/exclude locations to show the campaign.
