For Collins Pre-orders customers, when you send out a pre-order link to a customer, you can set the system up to automatically send out reminder emails to them. This can be set up to remind them 45, 30, 21, 14, 10, 7, 3 and 1 day before their booking.
To set this up, go to:
Venues > select the venue
Pre-orders tab on the left-hand side
Scroll down to Pre-Order Reminders
Tick which reminder you would like to send out. You can also leave a customised message here that will be added to the reminder email.
Make sure to SAVE the page
NOTE - these reminders will be sent out for all types of menus, so important to make them fairly generic eg about your cancellation policy or venue's contact details.
