There will always be distractions that keep your shoppers from pulling the trigger right away. Browser Tab Notifications improve retention & conversion by monitoring when your shoppers open a new tab, and changing the state of your favicon, title & even emitting a chime to remind your easily-distracted shoppers to come back and complete their purchase.
To enable this feature, go to your settings page and click on "Tab Abandonment".
In the below screenshot you'll see how when a user leaves your site (eg: opens up a new browser tab), after a short delay, they will see the title text of the tab change and hear an audio sound (optional).
