Change data in lead owner field
Prior to our switch to Salesforce, we were manually pushing in records from our CRM. If they were unowned (owned by marketing) accounts, we had logic that "assigned" these contacts to a fake sales rep--rather than have emails come from "marketing." We dynamically populate the reps' information in the emails, and any replies to unowned accounts are routed to a marketing inbox that is monitored by marketing and assigned out if necessary.
Now that we are synced with Salesforce, any unowned accounts are populated with owner names and emails such as as "Marketing User," or "Data Administrator." I would prefer not to have to send my batch emails separated by owned and unowned accounts due to the filtering out of random unowned account owner information populating into the emails. And it absolutely does not work for my triggered nurture campaigns. I had tried Velocity script tokens, but the logic ended up breaking the send.
Has anyone tried to change the data in the sales owner fields to a user that doesn't actually exist? I have racked my brain trying to figure out a way to do this simply.
