Help | Schedule announcements to multiple people

While you can not schedule a message to go out to multiple people in Slack, you can message multiple people with the schedule message app the same way you would normally message multiple people in Slack:

• Create a direct message with those people and schedule the message there
• Tag those two people in a channel they are in (tagging people works as expected in scheduled messages)
• Create a user group
• Use the Advanced Scheduler
