Same Cookie Id, Different Email Address

If the cookie id is the same, but the email is different, is a new lead created?

Yes, a new record is created (at least via Form Submission or List Import). If you use the API, you have multiple options based on the Lead Key you provide (email, cookie ID or Marketo ID).

Can you be more specific about the case you are asking about?

Re: Same Cookie Id, Different Email Address

A visitor is cookied, a new lead is created via the webservice api, the lead comes back and completes another form only this time with another email address.

I am assuming a new lead is created.  However we'd like to setup a process where if the cookie id is the same, and the first email is flagged as a bad email address, that the existing lead is simply updated instead.

In my experience, email address trumps cookie, so a new lead would be created. You could try deleting the first email address once you know it's bad.

In this scenario we do not have a name, only an email address and a cookie id, so how can we even manually identify a duplicate?

Also, this process needs to be automated.

Leads are getting created with the API.  Are we able to merge automatically based on cookie id?

I believe if you provide the Cookie ID as the Lead Key, it will update the same Lead, but please test this.

Jep, is this something we can do for a small set of leads we have flagged but not others?

Re: Same Cookie Id, Different Email Address

I can speak from experience that if a known lead comes back and completes a new form that a new lead record will be created and their cookie will be updated to point to that new lead, rather than the old one.

I'm curious, for the first time visitor visitor that is cookied, what action did they take to have the API create a new lead record for them if not filling out a form on your website / LP?

If by the cookie ID is the same, you mean the _mkto_trk cookie, they are indeed the same value for the first email address and after a form is submitted with a second email a, but they are associated with different lead records.  We use progressive profiling forms, so if someone changes the email address on a second form submit, the form doesn't capture the intiial information (e.g. first name, last name, company name).  We have a smart campaign that alerts us when a new lead is created without these elements and then we look for other leads with the same IP address, and will merge them if appropriate.
