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.
To do that you should follow the step here: How to properly Change and Test a New Email Recipient Address.
It will show you how to change the email, but also how to test if it is working properly.
I do however want to ask you to not post on various forum threads and open several different threads on the same subject because the system is likely to see you as spammer and remove your posts.
So in future it is best to open just a single one instead.
