Millennials communicate using instant messaging, text messaging, cell phones, but also traditional communication channels. Growing up communicating electronically, they love and expect communication mobility. Their desire is to obtain whatever they need to, independent of their geography or distance.
Millennials are much more likely to use instant or text message more frequently than email. They are also much less likely to send a mail letter than the older generations. Their communication is speeded by using shorthand, coded or abbreviated text.
