Limit participation by mail

I'm distributing a form's link via email.

How can I limit submissions to mail recipients only?

It can be achieved, by using the conditional logic of Jotform.

That is you would require to create a condition, so the "Submit" button only display if email field contains the required recipient email address, else it hides the submit button.

Please check the below screen shot:

That is the above condition, will hide the Submit button, if "E-mail" field will not contain the email address "test1@domain.com" or "test2@domain.com".

You can also verify it on my below test form:

Thanks for the super quick reply.

Any idea if this would work for 1000+ mails?

I wish to distribute the link to that list but not allow anyone outside that list to vote...

so we can make the mail field unique, so it couldn't be used twice, but can the matching be made for a huge mails list?

Yes, this will work for all the emails. As mentioned in the screenshot of previous post, you would require to put the email addresses by separating comma.

If you face difficulty to manage thousands of email addresses in a single condition, then you can create a new condition in the same way. And in that way you can manage multiple conditions easily for the huge list.
