Sometimes, products in your Shopify store are deleted, archived, or unlisted.
Deleted & Archived Products
In the case when a product or variant is deleted or archived, any customer subscriptions containing these items will be automatically paused to prevent missing items from subscription deliveries or unexpected transaction errors during billing.
From the customer's account, a banner will appear in these instances, guiding customers on necessary actions to resume their subscription. Whether it's swapping or removing the affected item, these changes aim to ensure a seamless experience for customers when needing to make adjustments to their subscriptions.

Customers will also receive an email notification informing them that their subscription has been paused. You can edit the contents of this email in your admin portal under Customer Notifications > Subscription Paused.
