Hey everyone!
With murm.io we've been developing a Net Promoter Score tool to gather customer feedback. So far our solution was based on a Javascript Widget that integrates with the checkout and allows store owners to receive feedback the minute an order has been created. Now we're been working on an email-based solution that allows store owners to automatically send emails after an order has been created, or fulfilled, or other webhook events Shopify provides. Configuration is done via a simple UI that looks like plain English (e.g. "Send an email survey 5 days after an order has been fulfilled."). It has never been easier ;)
We're just rolling this out slowly and we're giving access to everyone who would like to be in. Please register at https://apps.shopify.com/murm-io and let us know you want to try it out...
We're looking forward to working with you
