Thank you for reaching out to the Community about your email! I apologize your text is not displaying with the correct font size. I have taken a peek at your most recent email and was able to replicate this same experience. Was any of this text copied and pasted from an outside source? We have seen cases where pasting text from an outside source directly into an email campaign can carry over problematic formatting with it. I was able to remove this font size change through copying your text and pasting it as plain text into a brand new text block. This is something you can see in the Support Copy of your campaign that is available in your account.
In Constant Contact it looks fine, but on mobile, when I send a test email from your support version and open it, the fonts appear smaller in the side by side sections.
Thank you for following up with these details! I can see you also reached out about this experience in a second post in the Community. We have responded to this post with more information as well as a workaround.
I created a new text block and copied directly from notepad into my email. I am still seeing the same results. the side by side section text size is smaller than my other sections when viewing on mobile.
I apologize you are still having this experience after taking the suggested troubleshooting steps. Please email us a screenshot of what you are seeing along with the email client and type of mobile device you are using to social_support(at)constantcontact(dot)com. Once we get these details we can continue to troubleshoot this further for you!
