The opt-in trigger allows the user to choose whether they want to participate in the survey or not. If a user opts for the survey, only then they will be able to view the survey at the time of exit.
To set the Opt-In Trigger:
Go to:Login >> Customer Experience >> Create Survey
Create an Exit Intercept survey
Go to:Create Survey >> Select survey type 'Intercept'
Now input the incercept name. After the intercept name you have to select the 'Exit Survey' option
Select 'Exit Survey' >> Create Intercept
Now you have a exit survey. Now you can check or update setting for the intercept survey.
Go to:Survey >> Intercept >> Exit Popup Setting
To activate the 'Opt-In Trigger', turn on the Toggle button. You can customize the opt-in pop up title and message too.
When the user visits the website, then the Opt-in pop up will appear. It is based on the triggering rules set for the Exit survey. If it is set for 'New' user, only the new visitors will get the pop-up on their first visit to the website. If it is set for the 'Returning' user, then any returning visitor to the website will get the Opt-in Trigger.
If a user answers 'No', then the Exit survey will not appear. The user will not get another Opt-in trigger at the next time of their visit. In this case, they need to clear the cookies and cache to view opt-in trigger again.
