I've added a custom logo using the dimensions recommended for forms (300px x 52px). I found the quality wasn't good enough so I saved it slightly larger and it looks great in the form itself.
However, when the requestor selects "Send me a copy of my responses" and receives that email - the quality of the logo is significantly worse and appears pixelated.
I had loaded a larger quality one and it shifts from looking normal in the email to being HUGE and taking up too much space.
Any thoughts on a solution? Or is this simply something we can't get away from. Being in the Marketing department, it just doesn't look good on us to be sending communications with bad quality logos.
