Omnisend-legacy + Billsby Integration

If you're using Billsby to process payments on your website, you'll want to keep in mind that when a customer's order is created, a corresponding subscriber should also be created in Omnisend.

This will ensure that all future correspondence with the customer is tracked and attributed to that subscriber, making it easy to keep track of communications and transactions. In addition, automating this process will help ensure accuracy and efficiency.
