Image in newsletter not correctly

HI,
I was wondering if anyone could help me some coding for the newsletter html template. I have the issue that the image displays to far from the header, not sure if this could be caused by any other plugins as it was mentioned within the plugin instructions.

I was hoping that someone could help me code the template the right way so my images in a post show below the header.

As of right now the spacing is about the same size as the image (see attachment)
