The Email Subscription Integration feature allows you to collect email addresses from visitors on your Under Construction page and sync them directly with your preferred email marketing platforms— MailChimp, Klaviyo, Omnisend, or store them inside the app itself using App Storage.

This helps you build your email list and stay connected with your audience by sending updates about your store launch, news, promotions, and more.

Follow the steps below for the integration setup:
1. Go to your Shopify admin.
2. Open the app and navigate to Settings.
3. Select Email Subscription Integration, make changes as per your choice, and save them.
