What is Letterbox?

Who can access your emails? With traditional emails, you, the recipient, and all email service providers may have visibility into the contents, along with potential others. In contrast, end-to-end encryption restricts access solely to the sender and the intended recipients, ensuring greater privacy. The iOS app known as Letterbox enhances the end-to-end encryption experience, supporting a wide range of email services and employing the widely recognized OpenPGP encryption protocol. Although Letterbox operates like many other email applications, it specifically emphasizes the security status of both incoming and outgoing communications, empowering users to identify which emails are secure and which are not. Being a free and open-source email client for iOS, Letterbox aligns with an ongoing research project at Freie Universität Berlin. While it is still in development, users will soon have the chance to try the app on their devices via Apple's TestFlight platform, making secure communication increasingly available to the public. This development not only aims to improve user understanding of email security but also strives to maintain a seamless and intuitive user interface. As technology evolves, the importance of secure communication will only continue to grow.

What is Edison Mail?

Managing emails often takes up a significant portion of our day, typically revolving around themes of innovation and productivity. Over time, the core principles of effective communication have sadly become less clear. To address this issue, we initiated a project aimed at developing the ultimate mobile email experience. With clearly defined categories, the app's assistant organizes your messages efficiently, making your search much simpler. Just as peanut butter and jelly make a perfect pair, the features in this app work seamlessly together. Stay informed with timely notifications about your flight status, including any delays, cancellations, or changes to your gate. You can also monitor price drops on recent purchases, giving you the chance to save money through helpful alerts. The assistant provides access to weather updates for your trips, ensuring you pack appropriately for your destination. Additionally, you will receive real-time updates on your package deliveries, with easy access to tracking details through the assistant. If you're overwhelmed by newsletters and mailing lists, the app can help you pinpoint those that you might want to unsubscribe from. Furthermore, the assistant allows for quick access to directions for your upcoming flight or hotel, facilitating smooth navigation with just one tap. By integrating these various features, our goal is to significantly improve your email management experience and help you reclaim valuable time in your day.
