If You Use Slack, Read This

Slack is quickly becoming a de facto standard of corporate communications. I have scores of channels open across 8 Slack work spaces open on a regular basis. It can get overwhelming.

No one asked me, but I put together a few hints for using Slack most effectively in channels with large numbers of subscribers. Feel free to comment/argue below as you see fit.

In any heavily-subscribed channel, there could be dozens of messages flying around, and these tips will help keep everyone organized.

For these tips, I am assuming the mobile version of Slack.

  1. If you simply want to acknowledge a message with a "thanks," "me too", "+1", or anything like that, you can do that without cluttering up the message with a bunch of one-word replies. Tap the message text. On the screen that appears, tap the . . . button and choose the appropriate emoji.

  2. To reply to a message, use threads. Tap the message text. On the screen that appears, tap "Start a thread" if you are the first to reply. Otherwise, the thread replies will be displayed below the first message. In the latter case, simply type your reply in the "Add a reply" field at the bottom of the screen. There is a checkbox at the bottom of the screen labeled, "Also send to {channel}". Try not to use that, as it will also clutter up the main channel traffic.

  3. To send a direct message to someone from the channel, tap their name or image, and then tap the "Message" button. This will let you send a private message to that individual. You can also initiate a voice call from the same screen, though that may not be as reliable.

  4. You can tag specific individuals in messages and replies by typing @ followed by their Slack name.

  5. Unless you are one of the leaders or owners of the channel, please do not use @here or @channel in your messages, as that will alert everyone.

  6. A corollary to the above: in your notification settings for any channel you can choose to mute @here and @channel notifications entirely.


Communicating effectively in large groups requires diligence and discipline. Following the simple rules above will make discussions easier to follow and understand.
