There are many ways to communicate, and, generally, no one manner is superior to the others. What we often perceive as a superior method is far more likely to be a preference, and as a preference, we spend more time developing better skills there. People in business would do well to spend some time developing alternate strategies to get a message across because you never know when a problem is going to force you into some strange land of faxes and hand-written notes. Or text messages.
There's also the business of communicating such that the other person can get the message, and sometimes that other person has not had the opportunity, if not out of body experience, that engenders learning how to communicate beyond the basic face-to-face conversation. In such an instance, the one has to accommodate the need of the other. That, or just give it up and find another job. Or spouse. Yes, work is not all that much different from family in a good many aspects.
Email is a big deal where I work, mostly because of the asynchronous aspect of message delivery and receipt. I suspect it's also generational, but I have no evidence to support that claim. Of course, we use Exchange, just like so many others, and lately, Exchange has been bad, very bad. Or at least lonely.
We have two peeps who've been working overtime to keep our recalcitrant-of-late email going, especially the remote web access, and that's worth a standing ovation, though a card's gotta do for now.
