My "Problem": Every time I want to send a quick email I end up screening my other mail by accident. As soon as I open Spark (or Mail or Edison or Gmail or Thunderbird), the app fetches all my new emails. My best option is to try to close the window as soon as possible, but likely I will screen my inbox and lose my focus. I know this is a real first-world problem, but it bothers me terribly.
My goal is to be less distracted by incoming emails. Ideally, I would have two mail apps. App 1 only sends emails all day long. The program can be open all day. App 2 will only be started manually by me every day at a certain time or when needed, but actively triggered by me. Like opening my letterbox. App 2 should then fetch all my emails so I can reply to them or archive/delete them all in one go.
I tried to find the setting in Spark, Mail, Edison, and Thunderbird to stop fetching emails.
