It is possible to capture audience from an event.
It is called an event, when an user click on a button (CTA, sign a form, etc..) or a link, for example: "Read More".
To do so follow the instructions bellow
1- Go to your audience lists and click on "Event Link". A popup will appear
2- Enter the destination URL (where you want to direct the users)
3- Enter the text link you wish (which will appear as a hyperlink)
4- Select the background color and the text color.
5- Click on the "Create" button to get the preview of the new button.
6- Once you are satisfied, click over the first box to copy the 'audience tag' into your clipboard and paste it in the HTML of your assets before
the </Body> tag.
7- If you want a link, click over the second box to copy the tag into your clipboard and use the tag to create the link event you want.
You can use this CTA on your site / email and segment users who click that button.
Once they click on the button/ link, they will first be captured in the audience list and then will be redirected to the destination URL you set.
