On an iPad: If you click on the Houzz logo in the top left corner, it will take you to the home page. Then look along the bottom of the screen OR the menu will appear down the left side of the screen.

If the menu appears on the left, it will actually say "newsletters", otherwise, if you have a screen full of suggested photos, then you will see a menu along the bottom of the iPad screen, and you should see the word "Stories" which will take you to the latest batch of newsletters.
