I have one Gmail account made last year that has a
Sent Messages label and another Gmail account without it.
I think this was Gmail's default, but for some reason it was erased on the newer account, or Gmail stopped having that label somewhere. I tried finding the logic / rules for it, but there's nothing I can uncover to mimic it.
Does anyone know the formula for it?
I don't want it to label messages that are replies in my Inbox, just the ones in Sent.
I've looked through a few answers, and came up that I need the is:sent rule, but I don't know how to incorporate advanced parameters into a label filter.
