I can’t praise Unibox enough. It is by far the best new concept in email management I have ever seen. I started with Pine in 1992, then to Eudora in 1993, Outlook in 1998, Gmail in 2004, and now Unibox in 2016. How is Unibox different? Unibox is all about simplicity and helping you avoid information overload. In short, it displays your inbox by: (1) the name of the sender and (2) in chronological order. No subjects are displayed in the main view, period. The sender’s name is never displayed more than once in the chronological listing. Unibox groups all emails from the sender into one beautifully presented thread. Email subjects are not visible until you click the sender’s name to open the email (or thread, if the sender has ever emailed you before). Conveniently, you are (by default) presented with your entire email history with that sender in chronological order. One click will show you every attachment that sender has ever sent you, easily sortable by file type (in list view mode, or in a resizable thumbnail view mode). Who wants to look at a huge mess of email subjects when opening up your email client? What tends to matter most in email is the *sender* — and, secondarily, the subject — and Unibox has cleverly mastered this point. Managing your inbox with Unibox is a breeze and, to some degree, a pleasure. For example, have you received hundreds of transactional emails or newsletters from various senders over the years -- iTunes newsletters, perhaps? In two simple clicks on the sender’s name, you can Archive or Delete one or all of those emails. I suffered from e-mail overload from three different accounts for years. Unibox has helped master my email once again. Gone are the days of being overwhelmed by too many emails. This app was well worth the $16 I paid for it. One word of caution: Some other reviewers of this app were frustrated with Unibox because, I believe, they did not realize that the initial sync of all your emails and attachments details will take 1-3 days to sync fully. (In my case, I had about 300,000 emails in 26 gigabytes spanning 3 separate Gmail accounts. Unibox handled the import of the data with ease over about 2-3 days.) The full power of Unibox’s search capabilities and attachment view modes may not be completely apparent to you until the initial sync has completed, but it will be reasonably functional before that time.
