I should have received an event reminder I had scheduled to go out today, but didn't.
I have confirmed that the email was saved under the "schedule reminders" tab of the event.
I did notice that it didn't appear on the scheduled mailings here - /civicrm/mailing/browse/scheduled (but I'm still new to civi so not sure if they're supposed to show there or not).
I don't think I have configured everything for bulk mailing properly yet, but some emails do go out (like registration or membership confirmations).
