Learn how to sync BigCommerce email subscribers to a Klaviyo list.

Before you begin

The email subscriber sync is usually set up during the integration process. If you integrated without setting up the subscriber sync, continue reading to learn how to set it up. If needed, you can read our guide on getting started with BigCommerce for end to end integration instructions.

If you need a new list for these subscribers, create it before changing your BigCommerce integration settings:

Click the Audience dropdown and select Lists & segments.
Click Create, then select List. If you have no lists or segments yet, select List on the empty page.
Enter a name for your list, then click Create list.

How to sync subscribers to a list

In Klaviyo, select the Integrations tab.
Select BigCommerce to access your BigCommerce integration settings page.
Under Sync settings, check the box next to Sync your BigCommerce email subscribers to Klaviyo.

Choose the list that you’d like to add subscribers to. It’s best practice to add them to your main list such as your Email List. Note that you cannot select a segment; you must add your subscribers to a list.
Click Save at the bottom of the page.

Who will be added to my list?

Contacts who opt in during a checkout or through a BigCommerce footer form will be subscribed to the Klaviyo list you select. If the list uses double opt-in, new subscribers must confirm their subscription by email before they are added to the list.

Enabling this setting does not automatically add historical BigCommerce subscribers to the selected list.

Outcome

You've now learned how to sync BigCommerce email subscribers to a Klaviyo list.
