The duplicate matching is a powerful tool that helps you identify subscribers with identical content and merge them under a single subscriber ID. This ensures clarity in your lists and more precise communication with your recipients.

Key features:

• Detection of multiple entries based on freely selectable matching criteria
• Merging of duplicate groups under a single subscriber ID
• Retention of all list memberships of the merged subscribers
• Bundling of all activity data (clicks, opens) and interest values
• Various merging modes for maximum flexibility in data transfer

Benefits for your email marketing:

• Prevention of multiple deliveries to the same recipient
• Complete and accurate analysis of user behavior
• Improvement of sending statistics and target group definitions
• Higher professionalism in your communication

You decide how strict your duplicate matching should be by defining appropriate matching fields – from simple email addresses to complex combinations of multiple fields. After detecting duplicates, you can either merge them automatically or export them for manual processing.
