1. Find the original email you wish to duplicate from inside the main e-Marketing campaigns list.
2. Click on the duplicate icon as shown below in red to duplicate and rename the template.
When you duplicate an email ALWAYS use the duplicate listed first and then go in and rename the template - press the F5 key when viewing the main list and it will update the name of the campaign for you.
NEVER go into an old email and over-type into it as there are report statistics which will be associated to the original campaign and if you over-type into this email template and resend it will mess up your reporting stats by adding them to the old report statistics total.
