    How can I validate an email address that has been submitted?

    Asked by SpringBoardSafetyServices on June 12, 2012 at 04:33 AM

    I would a to be able to automatically send an email to the email address submitted so that the person can authenticate their email address before finally processing the form.

     

    I wish to use this facility for the signing up of newsletters, services etc.

     

    Thanks

    Hi Keith,

    What you applied on your form was the most that can be done to achieve validation on the email data.

    No way to prevent user from putting non-authentic email account as long as it meets the validation format. (i.e. invalid-email@invalid-domain.com will be a valid format but will not be authentic)

    But in your submission reports you can try filtering emails that were submitted and possibly isolate those that seem not authentic.

    Hope this help. Please inform us if you have further inquiry.

    Thanks.

    I have the same problem. The email authentication doesnt work. If someone enters the wrong email address, It still submits the form. It should warn the person signing the form that email is not Valid. 

     

    This will minimize the spammers that are actually filling out the forms in purpose. 

     

    Thanks

    Hello,

    The best way to minimize spammers from actually filling out your form is to add a CAPTCHA to your form. As my colleague mentioned, the email validation field only forces the user to enter a correctly formatted email address and it does not check to see if the email address actually works.

    Thanks!
