Avoid tagging "channel" or "here" in our auto-subscribed channels (#00) or any other channels with 20+ people. A simple, gentle guide to help you determine if the all-channel tag is appropriate:
Every DM results in a notification on the mobile and desktop devices of whoever you're trying to reach. And when you’re away from Slack for any length of time, those notifications can really stack up.
Even if you immediately follow up with your “real” message, the recipient gets a notification on that first “hey” that contains no information and potentially causes distraction. The person might see the indicator that you’re typing but is still left waiting for your full message.
You can start a DM with “hey” or with a 👋, but make it the first line of your entire message. Getting everything you need into a single direct message means that only one notification is sent to the person. Multiple messages mean multiple interruptions, and that’s far from an ideal use of everyone’s time and attention.
Hot tip: To draft a message with multiple paragraphs, press shift+return to create line breaks.
Use emoji, bulleted lists, and bold and italic text styling to make your titles and key points stand out in longer messages. This is especially useful for announcements or meeting recaps.
Well-formatted messages make text easier to scan and help minimize follow-up questions and messages, since important action items aren’t lost in lengthy paragraphs.
Emoji reactions are unsung heroes in Slack. They can communicate lots of different things to your team without needing everyone to post “I agree” messages.
Imagine you sent an email to your team with a new product idea. First, you’re met with total silence, then later a reply or two. You have to guess how the rest of the team feels, or you can ask at your next team meeting.
