Hey ​@Vadym - I think the best place for you to start is probably the inSidedData Object:

It won’t give you the email address natively, but it will give you the ID and username of the visitor.

Hi, thanks for the response! 🙃
I’ve looked into that object, but unfortunately it doesn’t provide access to the email.

I’d really like to understand how to do this properly step by step 🤔

Gotcha ​@Vadym - building something like that is beyond my skills but hopefully someone more technical will chime-in.  :)

Hey, there is perhaps a data protection reason why you can't retrieve user email addresses like that, no?

​@Vadym the following answer to this question provides a workaround of how you can achieve this:

Thanks!

​@olimarrio thanks a lot!
