When the order status is changed to Shipped (SHP), Sunrise can send email notification to the customer based on the following channel settings:
SEND_EMAIL_ON_SHP = Yes
This will send an email to the customer using the templates defined in the email template section of the channel (or master template).
If the template is empty, it will not send the email so is important to define the shipping notification template.
If you want to attach the order confirmation PDF to the email please set ATTACH_ORDER_ON_SHP = Yes
If you want to attach the invoice PDF to the order, please set ATTACH_INVOICE_ON_SHP = Yes
Note: if the order is not invoiced, the invoice cant be attached.
