The advantage of using an email client is that you don't have to open a web browser and log in to your mailbox every time; supports for new email reminder; allows to send emails to third-party applications (e.g., Evernote, Todoist, etc.), and so forth. Therefore, users who need to send and receive emails frequently always tend to use a desktop email client, rather than any web browser.

Postbox is a minimalist, dedicated, organized and universal mailbox management tool (namely, an email client software) for Windows and Mac platforms, developed based on Mozilla's Thunderbird, by several former developers of Mozilla in 2008, using the Mozilla's Gecko browser engine. It is able to manage multiple email accounts for a variety of popular online mailboxes simultaneously and uniformly within the same user interface, and allows user to subscribe to RSS feeds in order to read the latest news (newsgroups).

Postbox can sort and uniformly manage different email accounts without having to switch back and forth between them, which greatly simplifies email operations and improves the work efficiency. Besides, its classic panel layout and multi-label design make the entire UI orderly and flexible. Postbox's support for tagging, categorizing and searching emails is unbeatable, which is especially suitable for people with obsessive-compulsive disorder to information classification. It provides the Focus Pane function, which breaks the inbox (i.e.: the workload) into smaller, more manageable chunks, facilitating us to break every piece of email by identifying its priority.

Postbox tightly integrates the email and Todo List views, allowing us to see the outstanding tasks observably. And its fast search function comprehensively covers all kinds of contents from contacts to email text, attachments, images, and so on. Finally, Postbox puts a lot of effort into the surrounding details, and is easy to configure and use. Moreover, it not only provides a variety of additional extensions for downloading, but also comes with good interaction with various external applications.
