Works with CiviCRM 6.0 or higher.

Collect important mailing statistics, such as open and click-through rates, without compromising individual user privacy by decoupling tracking events from specific contacts.

When anonymous tracking is enabled for a given mailing, the extension saves the tracking data to dedicated anonymous storage tables thereby severing any link to the originating contact record. To calculate unique clicks without user identification, a non-reversible anonymous identifier (hash) is generated for each recipient. This process ensures that multiple clicks from the same recipient are counted as a single unique event, while making it computationally impossible to reverse the hash and identify the recipient.

This extension also provides two report templates:

  • Anonymous Mail Opened Report
  • Anonymous Mail Clickthroughs Report
