Email

BlitzMail is an Android app that allows you to set up your email account once and then use it to send emails or short notes to an address of your choice. This comes in handy when you need to send a lot of things via email, because you are in a low connectivity area (e.g. subway) and want to remember things to look at later. It also works when you are offline. BlitzMail then queues your emails and allows you to send them later when you have connectivity again. The SMTP password is stored encrypted with a built-in key and salted with your device ID. This is not fully secure, but should provide reasonable protection for your password.

Proof of concept e-mail (JMAP) client (pronounced \"Letters\"). Makes heavy use of Android Jetpack to be more maintainable than some of the other Android e-mail clients. Features, and design considerations: * Heavily cached, but not fully offline capable. Ltt.rs makes use of JMAP’s great caching capabilities. However, marking a thread as read does a round-trip to the server to update things such as read count. The action itself won’t get lost even if performed offline. * Account setup and done. Settings invite feature creep and its friend unmaintainability. There is one specific work flow. K-9 Mail or FairEmail is more suitable for others. * Minimal dependencies. Only widely known, highly tested libraries from reputable vendors. Third-party libraries are often of poor quality, and end up unmaintained. * First class Autocrypt. Ltt.rs fits right into its strict UX guidelines. * Based on jmap-mua, a headless e-mail client, or a library that handles everything an e-mail client would, aside from data storage and UI. There is also lttrs-cli, which uses the same library. * Looks to Gmail for inspiration in cases of uncertainty.
