Sending and receiving email has become a staple of enterprise communication. For some, working out of their email inbox is an all-day event. For others, email is still an important method of communication, but checking their inbox only happens a few times per day. For this reason, combining the necessity of email with the immediacy and efficiency of SMS was a no brainer.
So, now you can send your email, then send your contact a SMS from your email, to let them know they should check their inbox. Cool right?
