Help | Advanced scheduler

The advanced scheduler covers many more scenarios for scheduling messages. You can use it to:

• Send messages at a specific hour or minute
• Send messages at a specific timezone
• Send messages to specific channels, conversations or users
• Schedule message to multiple channels, conversations or users (up to 50 at once)
• Schedule longer messages up to 3,000 characters in length
• Use the datepicker to specific the exact date instead of working out how far it is in the future

Some things to note when using the advanced Slack message scheduler:

• Be careful when scheduling to lots of channels at once. Currently you will need to delete them individually, or delete all of your scheduled messages.
• If you don't set a timezone, it will default to your current timezone set in your profile. 
• If you don't set a user, conversation or channel it will default to the current channel
• The maximum number of combined channels, users or conversations you can schedule a message for at once is 50. If you need more please contact us with your use case.
• The date you select can not be in the past or more than 120 days in the future.
• If you have scheduled your message to a private channel, your success message will show the channel ID instead of the channel name.

Note for iOS Users - The advanced scheduler uses new features in Slack. If you are not seeing the dialog after typing /schedule please update the Slack app on your device.
