* Use a few bullet points to put attention on the main points you want to convey.
* Without going overboard, use a tasteful amount of graphic design (bolding one key sentence or whatever).
* Break up a giant nuanced email into sections.
* If something is critical, make it visual: a picture, explainer video, or an infographic can be really useful for something key.
This is harder than it looks. A quote attributed to Mark Twain is "I didn't have time to write a short letter, so I wrote a long one instead." It's a lot easier to go overboard than to distill what needs to be conveyed into the core elements.
1. Subjects with keywords. The subject clearly states the purpose of the email, and specifically, what you want them to do with your note. Keywords: ACTION, SIGN, INFO, DECISION, REQUEST, COORD
2. Bottom Line Up Front (BLUF). Lead your emails with a short, staccato statement that declares the purpose of the email and action required. The BLUF should quickly answer the five W’s: who, what, where, when, and why. An effective BLUF distills the most important information for the reader.
3. Be economical. Short emails are more effective than long ones, so try to fit all content in one pane, so the recipient doesn’t have to scroll. Use active voice, so it’s clear who is doing the action. If an email requires more explanation, you should list background information after the BLUF as bullet points so that recipients can quickly grasp your message. Link to attachments rather than attaching files. This will likely provide the most recent version of a file. Also, the site will verify that the recipient has the right security credentials to see the file, and you don’t inadvertently send a file to someone who isn’t permitted to view it.
