Can I limit form access to specific email addresses?

Hi

I work with a (nonprofit) organization that is looking for a form platform through which we can accept award nominations. But only people on our email list can submit nominations. With JotForm, can we upload an email list and have only people who are on our list be able to submit responses? Can we limit the responses like that?

Thanks!

Thank you! Unfortunately, the people eligible to complete the form don't share one domain, so we would have to be able to upload a list of approximately 4,000 addresses. But thank you for the quick answer!

You could use a similar set up but instead of using email address use a specific word or code.  Email that code then show the form contents only if the correct phrase is entered.  Similar to what is described in the following guide:

Makes sure not to label the field with the "Password" word, because our phishing detector system may suspend the form. Try using different labels such as "Access Key" or similar.

Right, but then we would have to set up 4,000 unique codes because again, if it was just one, it could (and would) be shared with people who aren't entitled to use the form. 

But thanks!

Unfortunately strict validation of 4,000 unique users without the possibility of sharing access would be a bit outside what would be possible through JotForm alone.  Even if unique codes were sent out, there would be no way to validate which codes had been used.
