Swym Back in Stock Alerts

Just to be clear, this review is for the FREE version of the app. It is nice to be able to keep a list of requests to be notified when products are back in, within Shopify. It would be nice if the free version allowed for an automatic message to be sent to a customer. There is no way to remove a notification from the list once you have sent someone a "back in stock" email. My understanding is that these features are available with the paid version. I don't expect a free version to have all the functionality of a paid version, but in this case, I feel like they could provide a bit more.
