You cannot send reminder messages to specific Heartbeat channels, but you have the option to send reminder emails and notifications when you create a Heartbeat event.

Where reminders show up

Every reminder appears in members' notifications in Heartbeat, under the bell icon on web and at the top of the app. It's removed 15 minutes after the Event starts.

A reminder sent 24 hours or less before the Event also goes out as a push notification, depending on each member's notification settings. It reads "Upcoming event", or "Event starting soon" in the last hour. So 2-day and 7-day reminders only appear in notifications, plus email if you turn it on below.

• Members who RSVP'd "No" still see the reminder in their notifications, but don't get a push.
• Members on a browser get a browser notification only if they've allowed notifications in that browser.

Sending reminders by email

To also send reminders by email, open Advanced Email Settings under Event Email Invitations, just above Event Reminders, and switch on Send event reminders as emails.

Reminder emails go to everyone invited except anyone who has RSVP’d "No". If Event Email Invitations is set to None, only members who have RSVP’d receive them.

If a reminder does not go out

A reminder only goes out if its send time is still in the future when you save the Event. Adding a 1 day before reminder to an Event that starts in six hours means that send time has already passed, so it is skipped and nothing is sent. Any reminders still ahead of the Event go out as normal, so on an Event six hours away, 1 day before is skipped and 10 minutes before still goes out.

When you are setting reminders close to the Event, pick a lead time shorter than the time left before it starts.

Events created with Pulse

Events that Pulse creates have no reminders, and Send event reminders as emails is off, so nothing goes out until you add them. Open the Event, click Edit and set them up as above.

A new Event created from the Events page copies its reminders from the last Event you created. If that one came from Pulse, the new Event starts without reminders too, so check Event Reminders before you save.
