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.
When it comes to customizing the feedback from your form, there are two places where your users receive feedback upon successful submission on your form.
1. They are shown a "thank you" message or page, which is confirming that their submissions was successful. You can customize the text of this thank you page or message that is shown:
2. Your form can also send an autoresponder email to the address your users have entered on your form. You can achieve that by following this guide:
While setting up the autoresponder, simply customize its text to whatever message you want or need to display to your users.
Please let us know how it goes. Cheers
