About

StackLetter is a research project at Slovak University of Technology. Our goal is to provide you with personalized newsletters for Stack Exchange Network sites.

Current newsletter problem

There are numerous posts on Meta Stack Exchange of people complaining about the state of the current newsletters, which are not interesting or personalized and often provide essentially random content.

What are we going to do differently?

We are making the newsletter personalized for each individual user by using machine learning and recommender systems to provide you with content that is relevant to you.

Additionally, we also dynamically adapt the newsletter structure based on your activity on Stack Exchange sites.

By using your implicit and explicit feedback, as well as your activity, our system is constantly learning what works for you.
