Salesforce inclusion list
I'm working with an enterprise level client on cleaning their HS portal. One of our issues in the sync list with SF. We need to change the criteria of the list.
My client brought up an issue that I'm not familiar with - the change to the list would cause all the contacts to resync to SF, in the sense that their records on SF would be modified and sales would get notifications about contacts that are already in salesforce and haven't necessarily taken any action (bottom line they should get notified about them and we're talking about over 3k contacts).
Is anyone familiar with this, how can make changes to the list without shaking the entire system?
