Sorry, I must have missed your last response, but can you calrify what feature do you want to use in FormsCentral? There are email receipts and email notifications. If you want the user to receive a copy of the date he entered in the form, then the user needs to enter an email address in the form and submit the form, but if you want the user to receive all responses he and others submit to a form, then it's email notification. It sounds like email receipts in your case. For email receipts to work, you need to have an email field in your form and set up Email Receipts in the options tab, by selecting the email field in the "To:" field.
I need email notifactions sent to this user. I checked all the emails sent to the users to share the form and there is no button to verify the email address. I need to verify the email address but I cannot find a way.
