We made Stackmash to make it easy for app or website creators to get instant notifications for their users activity. Originally built this for ourselves - we thought others may like to use a service like Stackmash. Being our first version, there are many features to come in the future such as being able to forward notifications to a number of services such as SMS, email, Slack or Telegram. As well as giving users the ability to control what shows as a notification and what doesn't. We are also going to let users integrate with IFTTT.

If you have any ideas or feedback, please let me know!
