For example, in a Mailchimp to Raisers Edge connection, there should be an option when setting up a formula to use items for matching but that doesn't meant when the records are matched that Mailchimp updates RE.

For instance, we have a lot of couples in our database, but they have separate emails so they have separate Mailchimp records. If somehow during triage/Needs Attention I miss that the names are different, or they go through to the Ready bucket and I miss it, then RE has been updated to 1 person's name thereby messing up the database.
