Getting to Email Headers & Footers
In order to get to Email Headers & Footers, click System Config, Email Headers & Footers
This should take you to the Email Template Layout List where you can select Edit to edit the existing Footer, Header or Style email template.
Editing Email Layout Templates
Click edit on the Edit button for the corresponding Section you wish to edit.
This will bring you to the template, in our case it is the Header Template. From here you can edit what appears on the header of each sent email as well as include inline styles.
Adjusting/Creating the Header and Footer Styles
The email layout template includes a Styles section which can be edited to reflect the style sheet of both your Header and Footer messages. You may also choose to add your styles inline using a style attribute between your tags. Or under the Styles section as mentioned before using the <style></style> tags.
