SFDC leads
Marketo created a new lead for us in salesforce because a they filled out one of our website forms. We wanted to test a few fields, so we filled out the same form with that leads email address to see if there were any merges, but we didn't see any changes so the lead and immediately marked it as test / invalid. Marketo however, moved that lead from out of the Test/Invalid queue to open LDD queue the following day and merged the two leads, updating all fields to that of the test lead (which was more recent). If a lead hasn't been converted, will leads with the same email address merge and take after the most recept post even if its been marked as test/invalid? How would i prevent that update?
