Customers not receiving email notification

There are three main reasons why your customer is not getting email notifications. 

1. Check that you have "[CUSTOMER]" entered into the email notification setting. Advanced > Administration > DC Settings > Email Notifications 
2. Check that you have the correct email address in the ship to contact information
3. Ask your customer to check their spam mail. If the email is found in spam, ask customer to add the email address to the safe sender list
