Block all Emails from a Specific Domain

Is there a widget or tool in Jotform to do this? See link below on a description of how to do this with your email client.

Thank you for reaching support,

Can you please elaborate on this?

Do you mean to block submissions coming from a specific email?

You could, however, implement unique submissions to prevent multiple submissions: https://www.jotform.com/help/64-how-to-set-unique-submissions-on-a-form/.

But kindly explain it further so we can understand better.

Awaiting your response.

Best.
