I wanted to share that you CAN adjust the font sizes by 1 pt at a time if you use one of their new templates. Apparently, I had been using an old template, and just copying it each month and adding/updating the content to send out, so the font sizes were limited. I contacted Customer Support and they told me that if I used one of the newer templates, I would be able to adjust the font to any size (and they were right!). You also have some other editing options available with the newer templates. It was not obvious to me what the newer templates are, but they had me search for 'cross-device editor' and many popped up. I would recommend choosing one and then checking the font sizing options before customizing it at all. It was a pain to copy my old formatting over to the new template, but once it was done, it allowed for so much more flexibility with the font sizing. Hope this helps!
