Klaviyo email marketing integration

With the Klaviyo email marketing integration you can connect your Back in Stock account to your Klaviyo store mailing list. Customers can opt-in to your mailing list at the same time as creating a Back in Stock notification. It is simple to setup and you can select which mailing list new customers are added to.

Once you setup the Klaviyo integration, a mailing list ‘opt-in’ checkbox will be added to your Back in Stock signup form. Customers who create a Back in Stock notification with the opt-in box checked will be added to your Klaviyo list.

Note: This integration is available to Back in Stock accounts on a paid plan or free trial period.

I’m using a theme integration for Retina, Mobilia, Responsive, Turbo, or Parallax. I’ve enabled Klaviyo integration but the checkbox doesn’t appear.

After you have enabled your Klaviyo integration simply install the theme integration again. The theme snippet will be updated to include the opt-in checkbox.
