Communicating with emails is not productive:
Email is one-way communication only
We get so much email, messages get lost
There is no way to set a reminder on an email so we simply forget to act
Communication with Apps is 2-way, actionable and instant
Actionable communication Apps give both sides of the communication an easy way to keep each other informed and complete expected tasks in a timely manner making use of automated reminders and prioritized task lists.
