No, I don’t mean every email you send has to be pure Emoji’s. Sometimes text is required to give context or extra meaning to your visuals (source: this sentence). That being said, often you can convey your meaning more efficiently with a smart visual than you could with the written word alone.
The truth is that humans have a shorter attention span than goldfish, and that isn’t going to be changing anytime soon. The average American worker is trying to be more effective and articulate, while managing a much bigger workload than we’ve ever seen in history.
We’re being pushed by necessity to make shorter and clearer emails that don’t waste the readers time and get straight to the point. We simply don’t have the time to waste—we must find the most efficient and effective form to communicate. Either writing emails or reading them; no one can digest an entire novella with every email.
