Hello,

i’m interested by tracking visitor’s email with the JAvascript Tracking Client, does someone know if it is possible with Matomo ?

Thanks

Hi,

You can save unique identifiers for users with the UserID feature:

Keep in mind that you have to follow all rules imposed by local privacy laws.

Hi Lukas,

Thank you for your answer.
User ID is a good start, however to get the email adress, the user must log in with a form. I’m pretty sure it’s possible to get the email adress without login, but i dont know how…
