You can set a timed?reminder on posts made in channels, direct messages, and group messages.
Hover over the message you want to remember, select the?More?...?option, then select?Remind.
Set a predefined delay of 30 mins, 1 hour or 2 hours, delay it to tomorrow or do custom delay for the reminder.
You’ll receive a direct message at the time you’ve chosen, with the body of the message you wanted to be?reminded about.
Note that once you’ve been?reminded about a message, you won’t receive another?reminder unless you set one.
