Mozilla Thunderbird is a free, safe, fast email client that’s easy to use. It has lots of great features, including quick message search, customizable views, support for IMAP/POP, RSS support, and more. Plus, the portable version leaves no personal information on the machine you run it on, so you can take your email and address book with you wherever you go.

Why do you need an email client? This is a valid question because you could log in to your web account and read and/or send your emails from there. With an email client, you can monitor and maintain all your email accounts in one central place. In Thunderbird, you can store all access information to all email accounts (e.g., info@yourcompany.com and your Gmail, Yahoo, and other accounts) and then choose a master password to access them all.

Wizard for setting up an email account

Before this feature existed, you had to know your IMAP, SMTP, and SSL/TLS settings. Now all you have to do is enter your name, email address, and password, and the setup wizard will check the Mozilla database and find the right email settings for you.

Add-ons Manager

Find and install add-ons directly in Thunderbird. You no longer need to visit the add-ons Web site. Instead, you can simply fire up the Add-ons Manager and install the add-ons you need.

Lightning, a calendar add-on that you can use to remind yourself of upcoming events or schedule meetings, is now already implemented into Thunderbird. It does not need to be added manually anymore.

Available for: Windows, Mac OS X, Linux

Note: If you are already using MS Outlook, you don’t need Thunderbird. Both email clients are suitable for taking care of your business needs, but Outlook is not for free.
