Mailbutler has introduced a major revamp to its user interface by adding a Sidebar. Mailbutler brings missing functionalities of modern emailing back to the users inbox, with time-saving tools such as snooze, send later, templates, signatures, tracking, and more. Offering better arrangement and easier access, the new user interface provides users with even a better and more organised inbox. Mailbutler is Free and can be downloaded from iTunes.
