Select Add Block after the first email and choose Integration. Although you can set the integration at any stage, we recommend doing it after the first email.

Here’s why: If the block is added post-trigger, all customers, including those who might recover their carts within an hour, are added to the list. So, placing the block after the first email ensures that even customers who’ve still abandoned their carts will get into the list.

  1. Click on the Integration block and choose MailerLite to configure.

  1. Select the MailerLite list where you want to add your customers.

  2. Click Save to apply the changes.

Note: Only one list can be added per block. If you need to add another list, you will need to create another block and add the list there.
