Email Templates, Email Containers, and Agreements can be the host to multiple images and/or files of your choosing. For this example, we will be uploading an image to an Email Container.
To upload an image to an email template, navigate to:
Email -- My Email Containers and click the pencil icon next to the template you want to edit.
Within the email template content, place your cursor where you would like the image to display.
Click the blue Upload Image button and choose the image that you have saved on your computer. The image will upload automatically and be placed at your cursor.
Once image is placed into your email container, remember to click on Save changes!
