Disadvantages
*
The Constant Contact Email History and Bounce History may not be retained since the ChamberMaster Contacts List will be cleared each time. Constant Contact only keeps history for 90 days anyway.
*
When importing the contacts from ChamberMaster, all of the Constant Contact fields are updated with the information from ChamberMaster. If custom fields or other contact information fields have manually been updated in Constant Contact, they would be overwritten by the information coming from ChamberMaster each time. If these additional fields are not being used by you in Constant Contact, then this will not affect you.
