Configuring your store to avoid sending multiple marketing e-mails to the same e-mail address

By adding a new attribute to the WebSphere Commerce configuration file, you can prevent the server from sending multiple e-mails to the same address for the same e-mail activity, even when the e-mail address belongs to different users. This ensures that a customer who registers as more than one user but supplies the same e-mail address for each user receives only one e-mail per e-mail activity.

Procedure

  1. Open the WebSphere Commerce configuration file.
  2. Locate the section of the file that starts with the <Instance element.
  3. Within the <Instance element, add the attribute filterDuplicateEmails="true", as shown in the following example:
    <Instance BootstrapMulti="wcs.bootstrap_multi_en_US.xml,"
                   . . . . . . . . .
                  InstanceName="demo"
                  filterDuplicateEmails="true"
                  InstanceType="local"
                  . . . . . . . . . . .
                  WCSInstallDir="D:\WebSphere\CommerceServer70"
                  WorkspacePath="" />
  4. Save and close the file.
  5. Propagate the changes to the WebSphere Commerce configuration file.
