Hi @miguelharrys1982, 
I wanted to extend our sincere apologies for missing your post here and for the delay in responding back to you. The Klaviyo Community is comprised of the greater Klaviyo ecosystem, including customers and partners, and is not monitored by the Klaviyo Customer Service teams. With the Klaviyo Community, we hope to provide Klaviyo users a platform to connect with thousands of entrepreneurs across the globe, and help each other when possible in navigating their e-commerce journeys. 

With your original question, it sounds like you’re looking for the most effective way to list-clean. This is a helpful article on how to list clean, and this section on deleting or suppressing unengaged segments may be what you’re looking for specifically. 

Hope this is helpful and again, our apologies for missing your first post. 
Thanks so much, 
-Cass.
