I was reading up on editing mapping(https://community.marketo.com/MarketoArticle?id=kA050000000LNRFCA4#map-unmapped-fields) and thought of something useful for organization, but am unsure on it's possibility.
Our organization gives leads a community email address after they convert to registered. We want to send out 'need to know' broadcasts to these new email addresses but because Marketo goes off the primary email field we are hitting the old lead email information.
What would be the simplest manner of editing the mapping to make this salesforce secondary email the marketo primary email (after a lead has converted).
Or would it be better to utilize the alert system some users have talked about, with custom tokens.
Thanks for any insight.
