Hi Jessica, Unfortunately, Marketo decides on which value to keep, and it will keep the most recent one. I've actually created an idea so that this can be fixed in Marketo, so that we can define if we want to keep the most recent or the oldest value for some cases (i.e. creation date of the lead). In the meantime, I created a new field (Mkto Created on) and a smart list to push the first Created date to this field (using a token). I made sure to block field updates for any source, so that once set, it cannot be modified, even inadvertently. When I merge two leads together, it asks me which value in this specific field I want to keep. That's my way to go around this in the meantime. Here's my flow: Hope this helps Emma
