Delaying a message in Slack

Desktop

1. Open the Mac, Microsoft Windows or Linux app, or use Slack from your browser at Slack.com. Choose your channel or search for a person to message directly in the search box at the top of your app or browser screen. Then type what you want to say in the blank conversation box. You won’t be able to schedule a reply to a message thread, what Slack calls a group of related messages.

2. Add any attachments, emojis, @ mentions and formatting that you desire.

3. Don’t click Enter. It will send your message immediately. Instead, click the down arrow icon v to the right of the paper airplane icon to schedule it for later. 

4. Select the date and time to send the message. You can choose from a list or select Custom time to choose another time based on half-hour increments | Schedule Message.

To edit, delete or reschedule a message, you can view the unsent message in two ways:

• Click Drafts & sent in the left rail and then choose Scheduled in the tabs on the new page.
• Or go to the channel where you created a delayed message and click on the link to See all scheduled messages.

Hover over the information that says when the message will be sent and choose whether to use the Edit pencil, Reschedule clock or Send now paper airplane. Click on the three vertical dots ⋮ to choose Cancel schedule and save to drafts or Delete message. If you choose Delete, Slack will give you one more chance to save your work.

Mobile

1. Open the Slack app for phones and tablets. Open the conversation or DM you’d like to schedule.

2. Click on the blank message field and type your message. Add any attachments, emojis, mentions or formatting. You can’t delay your response to a thread of messages here either.

3. Don’t tap the paper airplane icon, which will immediately send your message. Instead, tap and hold the paper airplane icon to schedule delivery later.

4. Choose from one of the dates and times on the list or click Custom time to specify your own timing and then tap Schedule Message. To edit, delete or reschedule a message, from the Home tab, tap Scheduled. Open the message you want to manage and long press somewhere in the text to bring up the options.   

You can always go old school and pick up a phone to share your idea, but scheduling a message to be delivered at the best time for your co-workers can be the best way to tell everyone simultaneously. You can get it done and check it off your to-do list even if your team won’t see it until hours later.
