* 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.
Hell, I've learned not to ask more than one question in an email. The first one is the only one to get answered.
For me, I tend to 'jump' to the first answer that comes to mind, without reading the full nuance, likely because I'm optimizing at replying sooner, so I can move onto the next task, because I have many tasks I need to do. I quickly pattern match and move on.
imagine times where you replied to emails partially
It will be hard for someone that always replies to the first thing only to empathize with this but: This has literally never happened to me. As in, I have never replied partially to something in an email. You will get an answer to each of your items. Granted, you may not get the answer you were looking for but I will answer each and every one, even if it's just a "I will have to look into this one and get back to you" so that the other 6 items can get answered right away.Why do the thorough people always have to empathize and not the other way around?
As the recipient, it's more challenging to receive the future promise of an answer with no SLA.
