Booking Verification Notification
Booking Verification Notification informs the users that they had a reservation and obliges the users to verify their order. The MEC plugin has an auto email section specifically designed for this purpose. Whether this email is sent or not depends on your settings for booking.
In order to manage this section you need to use the tags that are provided at the end of each section; you can send a cc of this email to the organizer as well. Other features of this option include the ability to send custom emails and using HTML tags.
