Existing SFDC data vs self-reported submission form data
When do you choose to override SFDC demographic data for a lead that already exists with new data that that lead self reports on a submission form? Is there a general rule for this or is it on a case-by-case basis? Or do you have a way of showing both "here's the email we had listed for this lead and here is the email that they self-reported" in their SFDC record?
