MessageBee allows you to upload a number of images that you can use in your templates. In order to get started, click the “Media Library” button.
A new window will open and all of your currently uploaded images will display.
In order to add a new image, select the orange plus icon.
A new window will load allowing you to upload an image. You will also want to write an image description and name as well.
Since the body of MessageBee messages is 500 pixels wide, this is the best width for any banner images you upload. Anything different than this will be resized to 500px wide. Banner height is a matter of preference. PNG or JPEG are optimal image formats
Once you are done, select upload and your new image will be uploaded to the media library.
