Compare STRING Values over X Time

Hello Everyone,

Sorry, I am kind of new to POWER BI and have a challenge where I failed so far finding a solution.

Basically I need to compare String values, in order to see if the users have touched their mails or not over the past x years.

I assume I’ll have to work with a measure, but both ROW and FILTER weren’t that helpful so far.

My data looks like:

Has anyone another approach on how to filter all the users who never had “Opened” or “Clicked” in the past x years?

Sorry, if this is the incorrect place for this question. Perhaps I am overthinking this as well, and the solution is very easy.

Thanks for your help!
