How to append Email Address to contacts currently in DB without it?
I've recently come into a new role and am working with a number of Marketo instances. Some of them have thousands of contacts without email addresses. I want to clean this up, and am working to get the emails so I can append them to the data.
My question is this:
How can I add (append) the correct email address to these contacts without completely removing them from the DB and re-uploading them with the appended email?
