    How can I avoid receiving wrong email addresses?

    Asked by jnnissen on June 16, 2015 at 03:15 PM

    I use the mailprogrm daily - but some times I need the correct sender-adress, because the sender does not write the adress correctly. I just receive the sender: Notifer 1

    Notifier 1 is the subject of the email. If you wish you can add the user's email to the notification's subject by clicking the right menu:

    I think I have to make it more clear:


    a customer sends an e-mail. The formlar completed, but unfortunately, the address is misspelled. Where can I see the correct sender address, as you can see in normal email korresponance.

    Unfortunately forms cannot be sent from the users email address, as this would need some authorization from the user to access the email account.
    But if you want to make sure that they fill in a valid email address you can use the email validator widget:


    1. User fills in his email

    2. A confirmation code is sent to his email

    3. Only after entering the confirmation code the form can be submitted

    Another option, more simple is to add an email field and activate the confirmation option:

    This way user has to type the email twice. This will reduce the typos but does not guarantee that it is a valid address.

    Now I have made the formula so that the custumer has to write the mail-adress twice. Is it possible to valdate, so that the first written line with the mail-adress is the same -  equal -  to the next written mail-adress.

    If you use the email field as described above, and activate the confirmation option, the second line  needs to be equal to the first line, else it will show an error message:
