I’m sorry, but you can’t find five minutes (if even) to read an email? No way your day-to-day life is so completely composed of things demanding your full attention that you don’t have a couple minutes to read an email. You typed out this comment, presumably after reading the thread. Surely you have time if someone you know sent you an email. You could read it in the time it takes to brush your teeth.
I think you're assuming my inbox activity looks like yours, and based on your comment I can assure you it does not.
Work only, I get 300+ per day. They're all valid and most of them go unread, especially the long ones. I also am in meetings most of the day, so email is not my highest priority. I scan and respond where essential, or often CC someone that I can delegate an action/decision to. Like I said, if things get urgent and I've not responded - people can find me other ways.
If email was as much as a priority to me as you want it to be, you're right, I probably wouldn't have time to respond here. I also wouldn't have time to use the restroom or sleep.
To flip the script, why are you composing full page emails? How much time does that take? Are you allergic to the phone? Do you want an answer? Do you want it timely? So on... as the sender in async communication, it's poor taste to jam wall of text infront of someone and have any expectation of when it will be read or acted on (same as the guy in the grocery store mentioned in this thread). The only exception is perhaps if it's from a superior and your job is to prioritize their communications - which of course I do, do that when I scan my inbox. There are people I always read and respond to, the vast majority of people sending me emails are not in that list.
