E-Commerce Configuration Guide : Setting up E-Commerce e-mail : E-mail formats
 
E-mail formats
 
The following settings are used to set the format (text or HTML) for e-mail generated through E-Commerce module (only edit the portion between the double-quotes that follows value=):
 
Site Admin Panel > Guest Related Settings > MailFormat value= text
Site Admin Panel > Guest Related Settings > SHMailFormat value= text
 
Set the value for either of these keys to text to use plain text e-mail templates or set to html to use HTML-formatted e-mail templates. Be sure to update the appropriate templates to include the wording you desire and update the pathname and filename for the templates as appropriate. See the section Editing e-mail templates for information on updating the default templates.
