What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
We can help you troubleshoot the cause of that if you can share to us the HTML codes of the notification email. I checked your form, but I can't find it there. Anyway, please try to check the width of that section and make sure to make it the same to the above table. As far as your screenshot is concern, the comment box is a separate table.
