How mailingmanager handles Duplicates
Mailingmanager has a few options when it comes to how you handle duplicate contacts.
The options on how you handle duplicates come when you are importing your contacts. There is a section called ‘Duplicates & Fields’. On this drop down there are three options.
The first option is ‘ignore any duplicate contacts’. This will ignore any contacts who is already in the system, it will only import new contacts from your import.
The second option is ‘Update existing contacts’. This will update the contacts information. If you are importing fields other than just the email address, make sure the information you are importing is up to date as this will overwrite the data in the account. You can also use this option to subscribe the contacts to a new list. This will not unsubscribe them from any list they may already be subscribed to but just add them to the new list.
The final option is ‘remove existing contacts and create new ones’. This option will wipe any data stored about the contacts including statistics. It will then create a fresh copy of the contacts with no data against them.
Mailingmanager only stores one version of a contact and just subscribes them to multiple lists instead of storing multiple versions of the same contact.
