Reducing Cart Abandonment is quite important because you don't want your customers to leave when they are on the final stage of order placement. There are multiple apps that can be helpful in getting back the customers.
Some of the apps that can reduce cart abandons are:
Cart Count Favicon
Grab your visitors attention by displaying the number of items left or added in the Add to Cart through their browsers favicon. Hence, even if the customer left the site, he will be pushed to redirect back to the site. Animate the favicon with multiple shapes, vibrant colours, animation styles, etc.
Inactive Tab Message
Bring your customers back to your store by displaying an eye-catchy icon and title. The message will bring them back to place the order successfully. You can customize the app with attractive icons and stunning tab titles.
Cart Reserved Timer
Setting a Cart Reserved Timer for your Shopify store is an excellent way to create a sense of urgency, prompting customers to check out quickly. Build FOMO (Fear Of Missing Out) and capture visitors attention. The app is fully customizable and offers several options to change icons, colour (background and text, countdown), heading, etc. You can also preview the app look & feel in the preview section.
