How They Design is a newsletter for curious people. People that are more interested in defining real problems and answering questions based on research and analysis rather than posting another trendy UI piece with long shadows.
Not all featured articles showcase real case studies. Some are written by passionate designers trying to crack small problems they spot in products they use every day. However, I always try to pick cases where authors follow a decent design process along the way. You can expect a defined problem and a whole process behind solving that particular issue.
What I can promise you is that you will definitely not find any clickbait articles in your mailbox.
