Once you have selected the email template you wish to edit, ensure you are in the 'content' mode at the top of the page
Select the text you would like to edit by clicking directly on the text box. This will open the 'Edit HTML Element' panel on the right hand side.
You can change the line height spacing of all the text or only some of the text.
To change the line height spacing of all of the text within the text box, click the global format button:
Select line height from the dropdown options and select the percentage you want from the choices.
To change the line height spacing of only some of the text, highlight the text you want to change and select the line height button. Then select the percentage you want.
Then click 'Save Element' at the bottom of the page, you will see your changes in the email template.
