By Marnix Geerkens. Published 2026-02-26. Updated 2026-06-02.

GoHighLevel calendars can send automatic confirmations, reminders, and rescheduling messages to clients without any manual work. Open any calendar, go to Notifications, toggle on the events you want, choose a channel like SMS or email, set who receives it, and define the timing. Once saved, GoHighLevel handles every message from that point forward.
