Your Check Cherry account has several automated email templates already set up for you to notify you of important activities on your account. One of these templates is the Design Selected email template.
You can view and/or edit this email template by going to Manage --> Automated Message and click on the Systems Templates tab.
To edit the template, simply click the Edit button to the right of the email template you want to edit.
As noted in the template setup, this email will automatically send you an email when a client selects a design template on their booking.
