Airmail for Mac is a new third party mail client that not only supports a plethora of account types, but is also one of the most visually appealing email apps for Mac I’ve ever used.
One of the coolest is a Today view widget for keeping tabs on the inbox, to-dos, or memos, although the application must be running in order to refresh such content.
Another favorite is integration with FTP servers and cloud storage services such as Dropbox and Google Drive. Choose one, select an attachment, and files are uploaded and covered to clickable links in outgoing messages.
Airmail is lighting fast, has just the right features, and has made the time I spend in my email so much more enjoyable.
