Design Pattern To Aleviate Retrieving Massive amount of rows from Database

I am currently building an Email web service using design patterns. I was using Lazy loading/proxy pattern to mitigate the load time. However, there are users that have hundreds or even thounsands of emails which takes minutes to load on the client side. I looked on the web for a solution by as of now I have found none that satisfies my needs. Is there a design pattern to call fragments of that information when its needed? Or do you know of any design patterns that solves this problem?

Thanks in advance
