    Hi,

    Unfortunately this feature is not available in Jotform. But if you know your web programming language then it maybe possible because Jotform allow users to download their form's full source code

    But if you mean user's should enter the right format of email address, then you may check my screenshot below:

    1. Click on your Email Field.

    2. Click on Validation above and Choose Email.

    If you have other concern or inqueries please do let us know.

    Thank you!
