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.
To collect emails from the people filling out your jotforms you should add the E-Mail field on the jotform.
To do that, you should click on the Quick Tools and then E-Mail field and just drag-n-drop to the jotform at the position you want it at.
Do let us know if you have any issues or further questions and we would be happy to help.
