The answer depends on the type of reminder and on how your workspace operates.
👉 On a programme with deadlines
Reminders sent before a course is overdue are built into Riot: they cannot be configured.
Reminders about overdue courses, on the other hand, are fully configurable: you can enable them, disable them and choose their frequency from the Awareness module settings.
Details are described in 2️⃣ Reminder notifications for Albert Courses.
👉 With Cyber Missions
The reminders above no longer exist. Your employees always receive a notification when their mission is launched. Reminders, however, can be disabled one by one in Settings → Cyber Mission:
the reminder sent 14 days before the deadline (Follow-up reminder) and the last reminder, 3 days before (Last reminder);
manager alerts (Manager escalation);
social nudges, linked to the progress of squads and the company (Social nudges).
The introduction message sent when an employee joins is also always sent.
👍 Good to know: if your goal is to reduce the number of messages without turning everything off, disable social nudges first: the end-of-mission reminders stay in place.
