Determining which User Clicked a Link

Identification of the user that clicked a link is based on a cookie Avanan adds to the clicking user's browser.

Identification procedure:

When a user clicks on a replaced link in an email sent to only one email address (click number 1), Avanan adds a cookie to the user's browser.
If the user clicks (click number 2) on another replaced link in an email using the same browser within 30 days of the previous click, and the email is sent to the same email address, the user's identity will be linked to that browser.
Click number 2 and all future clicks on replaced links (that are opened on the same browser) within the next 365 days will be attributed to the user, regardless of the number of email recipients.
After 365 days from click number 1, the cookie is removed from the browser, and the procedure restarts.

Example: Every row in this table describes a click on a replaced link by John Smith:


Date	Email recipients	John Smith's browser	Reported clicked user	Why the user is reported as the clicked user?
01 January 2023	John Smith	Cookie is added	Undetermined	One click is not enough to determine the user as John Smith.
02 January 2023	John Smith Mary Brown James Wilson	Cookie is still valid	Undetermined	Waiting for another click from this browser on links in emails with a single recipient.
03 January 2023 (or any date before 30 January 2023)	John Smith	Cookie is still valid	John Smith	John Smith clicked the replaced link (click number 2) in an email (sent only to one person) using the same browser within 30 days from the previous click. So, John Smith is reported as the clicked user.
20 February 2023 (or any date before 01 January 2024)	John Smith Mary Brown James Wilson	Cookie is still valid	John Smith	As the cookie is still valid, John Smith is reported as the clicked user though the email is sent to multiple users.
01 January 2024	John Smith	New cookie is added	Undetermined	Now, as 365 days are complete from the first click (click number 1), the old cookie is removed, a new cookie is added, and the user identification procedure starts again.
