Postbox is a nicely-designed utility created for people who use email services often. This application works with many IMAP or POP account types, such as Gmail, Yahoo!, Fastmail, iCloud, Outlook 365, and many others.
The Setup Assistant will help you easily configure the program according to your needs. Just enter your email account credentials and the application will immediately give you access to your messages. You can compose and send emails to any of your contacts, easily organize your messages, delete old online correspondences, and much more.
I like the fact that the program also provides you with various page arrangement options when composing new emails. You can adjust the size of the images you attach to your messages, insert tables on any area from the email, etc.
Another great aspect about this utility is that it brings you 70 professionally written email responses. These templates come in handy if you need to send a reply ASAP. They're perfect for hiring inquiry responses, collaboration requests, rejection letters, etc.
In conclusion, if you're looking for an efficient email client, Postbox is the right choice for you. It provides you with plenty of useful features, works perfectly, and is affordable.
