Thunderbird

Sending emails has become a very popular means of communication, no matter if you want to send messages to your friends or your work colleagues.

And while there are numerous solutions that can provide you with ease and use and attractive GUIs, Thunderbird still remains one of the most popular email clients out there.

Open-source, hassle-free email client

When installing Thunderbird for the first time, you can leave it to the app to automatically detect all the appropriate server settings for the email address you enter. Alternatively, you can manually enter the SMTP or IMAP details, then check if the connection is successful.

Once this step is completed, you can access the main window and explore the messages from your Inbox and the other folders you might have created (such as Drafts, Sent, Junk, Trash, Outbox, or custom ones like Archives, Important, and so on).

Supports many email operations

When it comes to reading your email messages, you can either use the preview panel or you can open them in a full-screen window - since Thunderbird supports tabs, you can open multiple messages side by side and explore them at the same time.

All the actions you can perform from the dedicated toolbar or menus can also be found in the right-click menu, so you can easily reply, forward or delete messages, as well as move to a new folder or assign relevant tags.

Easily customizable

Just like Mozilla's other flagship product, Firefox, Thunderbird can be personalized via extensions. You can not only tamper with its appearance by installing themes, but you can also enhance its functionality with dedicated add-ons.

Additionally, you can benefit from the built-in task manager and calendar to organize and track events so you do not miss any deadline.

Conclusion

In a nutshell, Thunderbird remains one of the most popular email clients out there due to its versatility and ease of use, thus making it suitable for novices and experts alike.
