I am using the Nexternal / MailChimp connection. When my customers first get added to my database, they default to customer type "Consumer". I change them later into a different customer type, but that is often an hour or a full day later. Will that customer type change get updated in MailChimp, or are they stuck at the type they were when they first entered my system?
If you have the systems set to autosynch, the autosynch list will update with your customer type change.
