Make sure to complete the previous step in our migration guide: Integrate your store with Klaviyo.
Switch out Jilt's signup form
If you're using Jilt's signup form to grow your newsletter list you'll want to make sure that you start capturing new subscribers with Klaviyo instead.
Turn off Jilt's signup popup form
From your Jilt account, go to Signup forms
Remove the checkmark next to "Enable popup forms to ask customers to opt into your marketing emails or broadcasts"

The "Enable signup forms" checkbox should be empty as shown above
Remove any embedded forms
For WooCommerce stores, you can manually add a shortcode to embed a signup form. It should be removed from any pages, widgets, or blocks on your store.
The basic shortcode appears as the following:
[jilt_subscribe]
It's possible to also use a built-in Jilt form widget, which we recommend you remove. More detail can be found here on working with Jilt's forms.
Enable Klaviyo's signup form
Klaviyo provides various form solutions as outlined here.
