I have used this method (https://salesforce.stackexchange.com/questions/233084/dynamic-from-address-from-name?noredirect=1&lq=1) in the past, option 2 specifically, to create a single send for my operations team that assigns the sender based on the state of the customer (and the sender is not associated with the account in any way in salesforce). Most of the time was spent waiting for those from addresses to verify their emails with Marketing Cloud (we're talking days of back and forth communication with the team). We're going to be looking into creating more dynamic sender profiles to send based on who owns the account in salesforce or who is the assigned sales rep in salesforce - will all of those emails also need to be verified? Is there a work around? Our turnover, especially in sales, is high and that's not something I can see realistically being manually maintained. Any work arounds? Thanks!
