After creating a theme using the Branding Guide or one from scratch, you can edit it by clicking Edit Theme under Branding. Select which theme you would like to edit and you will see the below window pop up. Edit the theme name, font, accent and text color, background image, color, and type. We recommend using a high resolution background image. You can also customize the send outs with CSS Code. Click Save, Delete, or Create New Version when finished.
