I'm using mu4e as my MUA and one the things that it offers are actions (something similar in mutt is macro) where you can map a keybind to some code that do something to the current message or the set of selected messages. This is generally the reason that a lot of mailing list recipients (high volume of messages) use those software, where you can refile messages very quickly leaving the more thoughtful reply things for later.
