Define Duplicate Elimination
To avoid unnecessary and, in most cases, unwanted double messages to the same recipient, use this page to remove duplicates from your recipient data.
Duplicates can be screened for removal based on one of three criteria:- Do not remove duplicates
All recipients with valid Internet email addresses will be used for sending, even if some of the recipients occur more than once in the source data. - Remove duplicates with same email address
Duplicate recipients that have the same email address will be deleted. This option can be helpful to screen out multiple names using the same email address. - Use my list of columns to determine duplicates
A list of column headers from the source data will become active when this option is selected. Choose any of the columns listed in the box to screen for duplicate recipients. This option can be valuable when there is a unique recipient ID column present. It will allow for different recipients who use the same email address to each receive a message. To select more than one column, hold the SHIFT or CTRL key down while clicking the desired columns.
The removed duplicate recipients are saved separately from the unique and the invalid recipients. All saved recipients sets are available for download on the Summary screen.
If the duplicate removal results are not acceptable, open the Duplicate Elimination
screen again to repeat the removal with different settings.
Note: Depending on the stored recipients attributes, it is possible to return
to a larger set of unique recipients by choosing a different criterion.
