Set up a Slack workflow that will send a message to a channel in the future. You can even set it to re-occur on a set time interval, like posting every Monday. This workflow is useful for any kind of reminder you want to send to a team — for example, to remind people to fill out their weekly timesheets, or post a standup update.
Configure when you want your workflow to start and whether it should be on a recurring schedule.
Design a message to be sent and set which channel you want your message to be sent to.
