How to prove completed form was sent back from the person you emailed it to ?

Hi - I have a form which I send to people who donate to our charity. The form is a declaration on their part allowing us to claim GiftAid tax on their donation. At the moment, the email I receive after the form has been filled in shows the sender as JotForm rather than the person named on the form.

In other words, there's nothing stopping me from completing the form myself and submitting it back to me with anyone details. Apart from adding the ip address to the confirmation email (which I'm assuming is the sender's ip), can JotForm make the confirmation email come from the person who fills the form in ?

Thanks for help.

Hello Peter.

If you are looking for a way to absolutely confirm that only the person who owns or has access to the email address provided to your form, is really the one submitting your form, you may want to use our E-mail Validator widget. (manual: How-to-Add-a-Widget-to-your-Form)

When using this widget, they will not be able to submit the form, until they have verified their email address - similar to the way registration works on most websites. They input their email address into the form, they receive a confirmation email with a special code, they input this special code, and then they can submit.

Here is a demo form of the feature: http://www.jotformpro.com/form/51533052113945

I believe that this will ensure proper verification of email addresses. Please let us know if you need further assistance, we will be happy to help.
