Badgy premium includes the ability to send welcome emails to your attendees before your event.
The welcome email text can be customised to your own preference and will include the users QR code that they will use to check-in.
In general the welcome email is sent the evening before the event. You can toggle on welcome email sending in the Event tab in Settings.
This feature reduces the check-in time for attendees by ensuring they have their QR code to hand when entering the event.
