Modify an existing template
Find the existing template

To create a new version of an old email, clone the existing template. Otherwise skip this step and go directly to the edit step.
Click on the template to open it, then click the "Clone" button.
Modify the email as needed
If the template type is HTML, you'll see a preview of the formatted email (example shown below) which you can edit directly with any changes. Note: If want to create a new HTML template, a letterhead is required and formatting is somewhat limited. Reach out to Phoebe Copeland with any questions.
If the template type is Custom (the type used for iContact imports), you'll see the html code rather than the formated version. If you need to make simple text edits, us Command+"F" to search for the portion of the email you need to alter and make the changes directly to that text. If you need to make a formatting change, building a completely new template via the lighting email builder is recommended.
