Scheduled and recurring reminders

Prepare an update now and deliver it when it matters. Team and Business include one-time and recurring scheduling.

Create a schedule

1. Open New message in the portal and write your message.
2. Choose an audience and review the live preview. Send a preview to yourself if needed.
3. Expand Schedule this message.
4. Set the First send, Timezone, and Repeat frequency.
5. Select Save & schedule.

The first send must be at least one minute in the future. Scheduling does not send a message immediately.

Frequencies and timezones

• Send once: one delivery at the selected time.
• Daily: the same local time each day.
• Weekly: the same weekday and local time each week.
• Monthly: the same day of the month and local time. A date such as the 31st uses the last day in shorter months, then returns to the original day when possible.

The timezone controls the entire send. It does not stagger delivery by each recipient’s timezone. Recurring reminders retain their local send time across daylight saving changes. Avoid times that fall in a daylight saving transition hour.

Review, pause or edit

Open Scheduled to see upcoming messages. Open a schedule for its next send, frequency and timezone. Select Pause & edit draft to cancel upcoming delivery and return it to Drafts. Edit and schedule it again when ready.

The scheduler uses the audience’s current members and rechecks workspace permission and plan limits when delivery is due. Each recurring delivery appears separately in Sent & responses, while the recurring schedule remains in Scheduled.

If a scheduled send cannot run

A permission, missing audience or plan-limit problem pauses the schedule and returns it to Drafts with an explanation. Correct the issue and schedule it again. Missed recurring occurrences are skipped rather than replayed as a burst of catch-up messages.

Delivery normally starts within a minute of the selected time when the scheduler and worker are running. A scheduler outage or Slack API delay can postpone delivery.

The timezone defaults to your Slack profile timezone. If it is unavailable, the browser timezone is selected, with UTC as a fallback. You can change it before scheduling.
