These days, we have an impressive number of ways to communicate with each other: texting, SnapChatting, video calling, Facebook messaging, Twitter direct messaging, and so many more. These newfangled (more or less) communications technologies get all the press and all the glory, not surprisingly. But when it comes to day-to-day, bread-and-butter communications, most of us fall back on good old email. It's not sexy, it hasn't changed all that much in a couple of decades, and whatever bells and whistles a developer adds to an email client are usually ignored. Email just gets the job done.
