You can configure Personal Discount to create unique discount codes for customers who abandoned their carts.
The set up comes down to selecting the Abandoned Cart trigger and specifying a time period after which a cart should be considered as abandoned.
Personal Discount adds a customer who abandoned a cart to the selected list in MailChimp. The app also creates a unique discount code and assigns it to the member's profile as a merge tag DSCNT_CODE.
In order to set up an automated cart recovery email you'll need an app that will synchronize the abandoned carts from your store to Mailchimp, for example ShopSync.
When configuring ShopSync you will need to choose the same list as you selected in Personal Discount. In my case the list is named Cart Recovery.
Next move is to open the automation wizard in Mailchimp:
You will be redirected to a modal where you can select if you want to create a single email or an email series:
Next step you need to synchronize the time period after which Mailchimp will send the abandoned cart email. Make sure it's the same as you specified in Personal Discount settings. In this example I've selected 1 hour.
Last step is to design the email template. The key thing will be to add include the Discount Code merge tag.
Once your email template is ready you can activate the automation by clicking on Start Sending.
