If you're sure the emails are going out, there's a couple of settings on your calendar you need to check.
Go into the calendar, click on the gear icon, and select "Options". Verify that "Allow email reminders for calendar events" is checked.
Next, go back to the gear icon, select "Subscriptions" and locate the calendar of interest. Make sure that "Allow email reminders for this calendar" is checked.
Last item, go to
https://ldsaccount.lds.org. Click "Contact and Recovery" and check your email settings there. I'm not sure which email the calendar may use, but I'd check all of those inboxes and spam folders.
