I'm a new GMail user, and I'm trying to figure out how to make labels work smoothly.
When I assign a label to an incoming message, it disappears from the inbox and appears in the folder(s) it has been assigned to. This is perfect.
When I assign a label to an outgoing message, it stays right where it is. It doesn't disappear from the Sent Mail folder. It doesn't even appear in the assigned folder(s). It just acquires a tag with the label name, which is useless.
I thought that clicking the Move to Inbox button might solve this. I found that it doesn't move a message to the Inbox; it just adds a "Inbox" tag to the subject line, which not only doesn't help, but doesn't even make sense.
I've looked for solutions to this problem in Support, but I didn't find any good ones. One was to assign the label before sending the message, which may solve some other problem, but doesn't affect this one. Another was to CC myself on every message I send and label the incoming copy, which sort of solves the problem, but replaces it with an equally bad one: it makes outgoing and incoming messages almost impossible to distinguish.
