I need to build a membership-based store that would sell subscriptions to a newsletter. I need something that would manage the orders / subscriptions, and allow me to deliver those newsletters through a separate platform. We have some specific requirements on how those newsletters are created and secured, and we can't deliver them through Shopify. So Shopify would just manage the subscribers and we would deliver outside of that. Is this doable?
This use case is possible with Shopify but probably with some additional apps.
You can use any of the subscription apps to manage subscriptions and use automation tools like zapier or our tool pandaflow to automate the notification/addition of that order to your newsletter management system if they have an API.
We use "Vindicia Subcribe" to manage the subscription side of our business which integrated with our Shopify ecomm site.
Works really well and has tons of flexibility for various promos and subscription types.
