I'm referring to the Slack website and not the Slack desktop program or phone application, as indicated by the tag.

This seems to do the trick:

from:me in:#random

... to list all messages I've posted in #random

  • What about a channel you're no longer a member of? Or a private channel? It won't show up in the auto-suggestions. – WEFX Apr 11 '19 at 14:33

    Or you can do just from:me and see everything you've posted in any channel, not just the ones you belong to...nice! – rogerdpack Nov 6 '19 at 15:44

    and, you can use from:me during:today to just find messages you posted today! Other date options that work are: on:today or before:June or during:week or after:2014 – Brad Parks Jan 14 '20 at 17:14
