Discover, manage & organize email newsletters in one place.


Letterbox is a dedicated inbox for newsletters that will save your time, boost your productivity, and bring the knowledge from newsletters all over the digital world in one place. We will provide you with custom-generated emails just for subscriptions. On our platform, you can discover, organize and save the newsletters you like the most. We divided them into categories - Entrepreneurship, Digital Marketing, Business, Remote Jobs, Cryptocurrency, NFTs, Programming, Investing, Tech, Design, and Productivity. Each newsletter on our site is personally selected by us, supported by solid research, and rated by quality. We greatly value the knowledge in them and want to solve the problem with unopened emails and spammed inboxes. We thought it would be amazing to build a simple and useful platform to get the most out of the newsletters.
