JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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.
Thank you for your feedback.
Unfortunately, this is not currently possible to expand the compose email window.
However, we hope that this issue will be addressed at some point. Our developers are currently working on rewriting the form builder piece by piece, and mentioned compose email section will be improved too.
