Follow up as I realize I did overlook your actual question :D I wrote how I answer, not how you can get my attention, but many of the points apply. Conciseness, clarity, and directness. What do you need from me, why do you need it, what actions are desired now, why is it important enough to write me directly? I realize this may sound bad from me, but I usually take the default that people don't need to write me, they just know who I am and write me anyways. They get delegated, and my team lets me know what I need to focus on or there are specific items in my mind that I know I need to focus on. So either be important enough to be in the inner circle, or make your points very clear on why _my direct involvement is needed_. If you can't define it, likely it's just not really needed, and it will be delegated out. But clarity of writing and conciseness is best.
