I like why. It helps me understand context. But in an increasingly email-laden world where everyone is “too busy” and emails are becoming more and more concise, the why is often the first thing to be omitted.
And this is a freaking travesty.
The “why” helps people understand why something is happening and the impact that it has. It gives context and, if it’s a request, it enables the recipients to use their own judgement and experience to assist above and beyond what’s originally being asked for (aka adding value). Not only that, but understanding the why makes people care more.
