I have read that I can use the gmail atom feed to get mails from “inbuilt” labels created by google.
But when I try to get mails from the “read” label, using https://mail.google.com/mail/feed/atom/read I get zero emails returned.
The same works if I use label:”read” in the search box.
Any idea if my usage of the atom feed is correct or wrong?
