I want to get the user e-mail when the user clicks a link on a newsletter sent to that user. Can somebody give any advice on how to achieve that.
Thanks in advance
A simple way to do this is to use UTM code out of Google Analytics.
Example:
https://placeholder.com/?utm_source=emailprovider&utm_medium=email&utm_campaign=stackoverflowquestion

Good luck.
