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.

If you are asking about sending email notifications from your form to an email address that is not registered for a JotForm account, you can certainly do that - recipient of email notifications doesn't need to be registered.
When setting up your email notification, simply enter your desired address in the Recipient Email field.
If you are instead asking how you can register a new JotForm account with a different email address, anyone can signup for a free JotForm account over our signup page:
Please let us know if you need any clarifications, or kindly clarify a little more if you were asking about something else, and we will be happy to help.
