Once a form is submitted a new lead is created and an Autoresponder is generated with a special Token that links to an Update Form. Clicking on a link to an Update form carries all the initial lead information with it.
Below is an example of an Autoresponder with the embedded Token. The token is hidden in the Click Here link.
Clicking the Click Here takes the recipient to a new form: an Update Form. Any information from this form updates the original lead!
Notice that fields that were completed with the original form: First Name, Last Name, Email and Phone are pre-filled with information FROM the original primary form. We didn't need to include them but they do give the recipient a good indication that this information is indeed about THEM. (Note: They can update it here if they need to.)
Any information they submit will update the lead.
