    Email Validation

    Asked by editioncount on July 03, 2014 at 06:03 PM

    We have validation on for a field for email addresses. Someone entered their address which was one letter but at a valid domain, for example r@jotform.com and they received an error. Any way to make sure that doesn't happen but keep validation? Is that common?

    This is now a part of security measure applied on the Email field in the form. It no longer allows one letter only email address format. It is now considered an invalid email if the email account is in such form.

    Any way to make sure that doesn't happen but keep validation?

    Not sure what you meant here, but the validation will not be removed.

    It will actually require the respondent to re-enter a valid email address/account.

    You may also want check the E-mail Validator widget for more advance e-mail validation process.


    Hope this help. Inform us if you need more assistance.
