Slack Reminders: How to Set Up and Use Them

Slack reminders are one of the most useful features hiding in plain sight. With a single slash command, you can nudge yourself about a deadline, prompt a channel to review open items, or schedule a recurring follow-up that runs every week without you thinking about it.

For operational teams running HR, Finance, or internal support through Slack, reminders are the simplest way to keep routine tasks on track without adding another tool to the stack. This guide covers how to set them up, the most useful patterns for ops teams, and where reminders start to hit their limits.

TL;DR:

• Use /remind to set personal, channel, or recurring reminders in seconds.
• Personal reminders work for follow-ups and deadlines. Channel reminders keep teams aligned on recurring tasks.
• HR and Finance ops teams get the most value from recurring reminders for things like expense deadlines, onboarding checklists, and approval follow-ups.
• When reminders can't handle shared ownership, approvals, or visibility, it's time to add structure underneath.

What Are Slack Reminders?

Slack reminders are a built-in feature that lets you schedule notifications for yourself or a channel at a specific date and time. When the reminder fires, Slackbot sends a notification with whatever message you set. You can create one-time reminders or recurring ones that repeat on a schedule.

Reminders live in the Later tab in your Slack sidebar, where you can view, edit, complete, or delete them. They're lightweight by design: no setup, no configuration, no third-party app required.

How Do You Set Up Slack Reminders?

There are three ways to create reminders in Slack, depending on what you need.

Set a Personal Reminder with /remind

Type /remind in any message field and Slack will prompt you to fill in the details: what the reminder is about, and when you want to be notified.

You can also type the full command directly:

• /remind me to follow up on the benefits enrollment email tomorrow at 10 am
• /remind me to review the Q2 expense reports on Friday at 2 pm
• /remind me to check onboarding status in 3 hours

Slack's parser understands natural language for dates and times. "Tomorrow at 9 am," "next Monday," "in 2 hours," and "every Friday at 3 pm" all work. For best results, use the American English date format. If Slack can't parse the time, it will ask you to clarify instead of failing silently.

Once set, you'll get a Slackbot confirmation message immediately. When the time arrives, Slackbot sends a notification and adds a badge to your Later and Activity tabs. From the notification, you can mark the reminder complete, snooze it, or delete it.

Set a Channel Reminder

Channel reminders send a Slackbot message to the entire channel at the scheduled time. This makes them useful for shared deadlines and recurring team rituals where everyone needs the same nudge. Use this format:

• /remind #finance-ops to submit expense reports every Friday at 11 am
• /remind #hr-team to review open onboarding tickets every Monday at 9 am
• /remind #it-support to check SLA status every day at 4 pm

Channel reminders are visible to everyone in the channel, which makes them useful for shared accountability. Note that channel reminders can't be edited after creation and don't appear in your Later tab. You'll need to delete and recreate them if anything changes. Guests can set personal reminders but not channel reminders.

Set a Reminder on a Specific Message

Hover over any Slack message, click the three dots menu, and select "Remind me about this." Slack will prompt you to choose a time. This is the fastest option when someone posts a request, question, or piece of information you can't address immediately, but don't want to lose track of. The reminder will link back to the original message, so you get full context when it fires.

How Do You Manage and View Your Reminders?

All your active reminders live in the Later tab in your Slack sidebar. From there, you can:

• Mark reminders complete when the task is done
• Reschedule by clicking the clock icon and picking a new time
• Delete reminders that are no longer relevant

You can also type /remind list in any conversation to see all your pending reminders. This works as a quick daily triage: check what's due, clear what's done, reschedule what needs more time.

One limitation worth knowing: the Later tab groups everything together. Saved messages, reminders, and snoozed items all share the same list with no filtering or categorization. If you're an active reminder user, it can get cluttered fast. Building a morning habit of reviewing and clearing the list keeps it manageable.

What Are the Most Useful Slack Reminder Patterns for Ops Teams?

Reminders are most valuable when they're tied to recurring operational workflows. Here are the patterns that HR, Finance, and internal ops teams use most.

Onboarding and Offboarding Checklists

Set reminders for each step in a new hire's first week: IT provisioning follow-up on day one, benefits enrollment reminder on day three, manager check-in prompt on day five. For offboarding, remind yourself to confirm equipment return, access revocation, and exit interview scheduling.

• /remind me to confirm laptop provisioning for [new hire] on Monday at 9 am
• /remind #hr-team to send benefits enrollment reminder to new cohort every first Monday

Expense and Reporting Deadlines

Finance ops teams can use channel reminders to nudge teams ahead of deadlines instead of sending manual Slack messages each cycle.

• /remind #all-teams to submit expense reports by EOD Friday every Thursday at 10 am
• /remind #finance-ops to close monthly books on the 28th of every month

Approval Follow-Ups

When you're waiting on a manager approval, budget sign-off, or policy review, set a personal reminder to follow up if you haven't heard back within a reasonable window.

• /remind me to follow up on [manager]'s approval for the new hire offer in 24 hours
• /remind me to check vendor contract status on Wednesday at 2 pm

Recurring Team Rituals

Keep lightweight team habits running without calendar invites:

• /remind #people-ops to share weekly onboarding status update every Friday at 3 pm
• /remind #finance-ops to review open purchase requests every Monday at 10 am

Policy and Compliance Nudges

Use reminders for periodic checks that don't warrant a full project:

• /remind me to review access permissions quarterly on the 1st of January, April, July, October
• /remind #hr-team to update employee handbook sections every first Monday
• /remind #finance-ops to reconcile vendor invoices on the 15th of every month

Standup and Status Prompts

Replace a standing meeting with a channel reminder that prompts async updates:

• /remind #people-ops Hey team, what's your focus today? every weekday at 9:30 am
• /remind #finance-ops Post your weekly status update every Friday at 2 pm

This works especially well for distributed teams across time zones, where synchronous standups don't fit everyone's schedule.

What Are Common Slack Reminder Issues and How Do You Fix Them?

Slack reminders are reliable, but a few quirks catch people off guard. Here's what to check when something isn't working.

Reminder didn't fire. Check your reminder list with /remind list to confirm it was created. If it's missing, the original command may have had a formatting issue. Recreate it with the standard /remind [who] [what] [when] format and verify Slack confirms it.

Wrong time zone. Reminders fire based on the time zone in your Slack profile, not your device's local time. If reminders are triggering at unexpected times, go to Preferences, then Language & Region, and confirm your time zone is set correctly. This is the most common issue for remote teams working across regions.

Channel reminder can't be edited. This is a Slack limitation, not a bug. Channel reminders don't appear in the Later tab and can't be modified after creation. To change one, delete it and create a new one with the updated details.

Do Not Disturb is blocking notifications. If DND is active, Slack suppresses all notifications, including reminders. Check your DND schedule in Preferences and make sure it's not overriding your reminder times.

Reminder notifications not appearing on mobile. Ensure Slack has notification permissions enabled in your device settings. On iOS, check Settings, then Notifications, then Slack. On Android, check Settings, then Apps, then Slack, then Notifications. If notifications still don't appear, try clearing the app cache or reinstalling.

When Do Slack Reminders Stop Being Enough?

Slack reminders work well for personal task management and simple team nudges. But for operational teams handling a real volume of requests, there's a point where reminders start masking problems they can't solve.

Here's what that looks like:

No shared ownership. A reminder fires, but only you see it. If you're out sick or pulled into something else, nobody picks it up. The task falls through because it lives in your personal queue, not a team-visible system.

No approval routing. You can remind yourself to follow up on an approval, but you can't route the approval itself. If an onboarding checklist needs sign-off from IT, Finance, and the hiring manager, you're still the one chasing each step manually.

No visibility into what's open. Reminders don't aggregate. You can't pull up a dashboard showing how many onboarding tasks are in progress, which expense approvals are overdue, or where requests are stuck. When leadership asks for status, you're digging through Slack threads.

No tracking or history. Once a reminder is dismissed, it's gone. There's no record of what was handled, how long it took, or what patterns keep recurring. You can't improve a process you can't measure.

If you're recognizing these patterns, you haven't outgrown Slack. You've outgrown unstructured Slack. The next step isn't a new tool your team has to learn. It's adding structure to the Slack workflows you already run: shared request queues, automated routing, approval workflows, and operational visibility, all inside the same Slack channels your team already uses.

Getting Started with Slack Reminders

Slack reminders are the fastest way to stay on top of tasks, deadlines, and follow-ups without leaving your workspace. Start with personal reminders for your own to-dos, add channel reminders for shared team rhythms, and build the habit of checking /remind list each morning as a lightweight daily triage.
