My email template for my broadcast has a photo in the header. Within the template I have typed our company name in white font to appear over the background photo in the header. Unfortunately, when I send a preview to my email, my email program Spark displays the header wrong - the company name displays in black letters (on the dark background of the photo) in the header. It looks really bad. Gmail and Spike display correctly. What do I do, please? For all I know, some of my subscribers are using Spark as well...
