On the emails tab you can define your store email address, where new order emails should be sent to and a bunch of other general email settings.
Email Recipient Options
Define which email address will receive new order and stock notification emails.
Email Sender Options
Define your stores ‘from email name’ and ‘from email address’. E.G. Jay’s Widgets. sales@jayswidgets.com
Email template
Here you can add a custom header graphic to your store emails. A good width to make this image would be 600px. If you have any store specific information such as phone numbers or additional contact details these can be added to your email footer.
Best of all you can make the WooCommerce emails match your brand identity by modifying colours of certain elements. The background colour of these inputs matches your selection (in hex).
