Hi @Mogens ,

Welcome to the Community! 

Thank you for your question about segment definitions. I agree that it certainly sounds easy to have a magic button to remove someone from a segment However, segments are actually meant to work dynamically based on the logic you pre-define; taking the manual work out of it! So let’s see if we can better define your segment to work for your use case:

Are there any similar traits among the people you want to exclude from this segment? If so, you can add this logic to your segment definition with an AND connector to automatically exclude those users. 

I’m not sure what your particular use case is, but you can use this to exclude recent purchasers, contacts in a certain list, where someone is located, and more! (just to give you some ideas).

There is also an excellent article on Getting started with segments on the Klaviyo Help Center that may give your a better understanding of the options available to you in Klaviyo. 

Hope this helps!

Hi Mogens, 
I think you can try this as a workaround: Create a flow with email(s) for that specific segment. And place a link in an email that tells customers: “If you want to be removed from this segment, click here.” And then, under the email, create a conditional split to check if they clicked the link. If they click, create a new custom property to define people who want to be removed from this segment. And then update the definition of the segment to exclude people with that newly created property. 
Hope that helps!
