Edit your mail configuration by going to Store Manager->Mail Configuration. Click on Messages in the top navigation to edit the text within all auto-generated outgoing emails.

• Administrator email. - this is the email address that is displayed on the contact us form. It is also the email to where all administrator order confirmations are sent.
• Outbound emails will be labeled as coming from this email address. - when the system sends out an email (newsletters, order confirmation or status changes, etc.) this is the email address it uses as the From address.
• Optional fulfillment officer email. If you enter an email address here, a copy of each order will be sent to this address -- at the time of order. - if you would like another person (in addition to the administrator), enter that email address here. This is optional and you can leave it blank if you don't need a second email.
• Disable the default customer email at SaveOrder Step. - if you don't want an email to be sent to the customer when they click the "Finalize Order" button (before they actually pay), the set this to disabled.
