Hello @JustWriteComms. I sent a preview of your newsletter over to my mobile device (iPhone) and I do see that two of the stories do have a smaller text size. This can happen if text is copied and pasted into your Constant Contact newsletter. If you are copy/pasting text into your newsletter, we recommend first pasting your text into either Notepad (Windows) or TextEdit (Mac) and then taking that text and copy/pasting it into your newsletter. This can strip out a lot of formatting that can cause issues like you were seeing. I have some more information about using this suggestion here.
Shouldn't your editor or preview tool catch that?
Whats the purpose of a preview tool then?
Are you saying you can't depend on that for something as basic as font size?
I have gone through every section after copying and pasting in plain text and reformatted the content to have the same font size, yet when I preview my newsletter using my mobile, the font sizes automatically change arbitrarily - some sections are 12 ft and some are 14 ft. What can I do to avoid this? This is a very frustrating issue that I think Constant Contact needs to address.
I apologize that you are having this experience as well. Sometimes copy and paste will cause this issue even if you are pasting in as plain text. You will want to try typing in the text manually or you can copy and paste your text into Notepad or Textedit first to strip any unwanted code before you paste into Constant Contact.
