Allow SMS back-in-stock notifications only for specific countries (e.g., US) while sending email for others

A merchant requested the ability to send back-in-stock notifications via different channels depending on the customer’s country. Specifically, they want SMS notifications to be sent only to customers in the United States, while customers from all other countries should receive the notification via email instead. Currently, Notify Me does not provide a way to configure notification channels based on the customer’s geographic location. The merchant would like a rule or setting that allows channel selection (SMS vs email) depending on the customer’s country. Example use case: - Customers in the United States → receive back-in-stock notifications via SMS - Customers in all other countries → receive back-in-stock notifications via email This would help merchants control SMS costs and tailor communication channels by region.
