I used the Marketo standard email design template. It looks good. Then I ran it through 250ok and a few test platforms. WTF?
That horrible green color you see does not exist ANYWHERE in the html of the email (got the hexcode for that color - searched the code - doesn't exist). Not only that, but the 250ok engine shows this for my primary email platform
Am I going to have to go with a non-Marketo solution to create cross-platform compatibility?
