Pinpointe allows you to merge two or more databases into a new, clean database. When complete, you will have the option to name/rename the new merged database.  

Operation Notes:

• The newly created database does not carry along any historic data or statistics regarding email opens, campaigns sent, etc. The purpose of merging two or more lists is to create a new, clean database of active contacts.  
• Bounced emails are not included in the newly created merged database. 
  
• When merging is complete, the original databases will still remain. These databases still retain the historical information, including open and click statistics.
  

Note: If you delete the original source database - you will lose historical statistics and campaign results for the original lists you delete.  This includes any historical campaign statistics associated with the original lists, email queue logs associated with the original lists and per-contact event details such as clicks and opens.

To merge two or more databases, do the following:
