To use images in your emails they’ll need to be hosted somewhere online. You’re welcome to use the images hosted on your website or anywhere else, but to make things simpler we give you some storage space called the upload library that allows you to access these easily from within your account.
You can add images to this directly from within the drag & drop editor and the html editor, otherwise use either the following video or the step by step guide underneath.
First go to content and select upload library.

Click on the choose file button and select the image that you want to upload. Then, select upload file, and the image will be added to the upload library.
Note that if you’d like to add images in bulk, let us know and we can send you your ftp login to access the upload library directly.
