I apologize that the PDF still isn't rendering as intended after everything! I have another idea for you to try. If the PDF is meant to be the whole email what I recommend is try splitting the PDF in two. Splitting PDF into two separate PDF's might allow you to increase the quality of the images. Once the two halves are uploaded into your account, you will be able to add them to your campaign and have them touch so they still look like one big file. Please let me know if you need me to elaborate on this more!
