GIF, TIFF, JPG, BMP, PNG, EPS…after a while, image file type names start to just look like gibberish. So with the plethora of file types out there, how do you know which is the best image format for your email marketing? Some formats don’t work uniformly on every browser (emojis, anyone?). Some don’t show off your photographs in their every detail. Unfortunately, there is no magic image format that will work for your every need. It varies from photo to photo depending on the image and how you plan to use it.
