Twobird is an email application that gathers all your daily tasks in one tool to save time and increase productivity.
Beyond sending emails, you can also write notes, create reminders and work collaboratively with other people, without leaving your inbox.
This tool was created by the developers of Notability, an iOS note creation app, and is intended to be its successor. Twobird allows you to put together shared notes within an email so you can see everyone's ideas together in real-time.
Finally, if you're wondering why you should use an extra app to read your mail instead of directly from your usual server, you should know that Twobird has many useful features, such as hiding signatures and complex formats to speed up the reading of your emails, allowing mentions, correcting typos or intelligently deleting newsletter subscriptions.
