Extra things that can make your mail sing
Airmail is packed with goodies: integration with cloud file storage, HTML and Markdown coding, almost infinite customisation and more menu options than you can shake a stick at. As you might expect from a Microsoft Office app, Outlook does everything: there’s integrated calendar, contacts, tasks and notes, and the ability to forward emails to make meetings, plus cloud file support. Thunderbird offers extensions plus integrated calendar and tasks too, plus newsgroup reading and chat, while Postbox offers extensions that you can use to add calendars, to-do lists, meeting scheduling, effortless use of canned responses, Markdown and stacks of other features. It doesn’t have the sheer number of extensions that Thunderbird has, but the list is more focussed and well worth exploring.
Compared to the other apps here Mailbox doesn’t do much, but that’s deliberate: it’s about spending less time in email, rather than using endless features. Unibox is similar, emphasising ease of use over power tools for pros.
Postbox’s power features take time to learn but they’re well worth the effort.
