Most of my clients use Outlook. I do not. More accurately, I have not. For the past few years I have been using emClient. emClient has some features which Outlook does not have or does not implement well that I like.
- Works well with multiple email services
- Shows all email in a unified Inbox. Like Apple Mail on iOS.
- Cleaner/less cluttered interface.
- Easy to send mail at a later time.
Recently, the use of a unified Inbox got to be overwhelming and I have begun to look at transitioning back to Outlook.
Outlook has improved a lot and it still has its annoyances.
Something I like about Outlook...
...it remembers the last few folders that you have moved messages to making it easy to file emails away.
