What is an email client?
If you are accustomed to using email through your web browser at websites like gmail.com or outlook.com, then the concept of an email client may be unfamiliar to you.
Today, many people manage their email on the web using services such as Gmail.com or Outlook.com. These webmail email service providers offer access to email accounts through any web browser. It is convenient because you can get your email from almost any computer. If you are away from home for work or vacation you can easily check your email on somebody else’s computer.
Another way to handle your email is to use an email client program like Thunderbird or Apple Mail or Outlook installed on your own computer. A program like this offers many advantages over using a web email client. It lets you organize your email exactly how you want, it enables you to read and search your email when you are offline, and you can manage multiple email accounts (e.g. your work gmail and your personal gmail and your personal outlook accounts) in one place. Of course, desktop email clients and web email clients can coexist side-by-side. Using an email client at home does not preclude you from using webmail if, for example, you want to check your account while you are on the road without your computer which has the email client.
Thunderbird is a feature-rich, reliable, and secure email client for managing your email. It's free and open source. Thunderbird has been around since 2004, and is used by many people around the world. Best of all, it runs on Windows, macOS and Linux. You can connect to any email service that supports email standards (e.g. POP, IMAP and SMTP), including Outlook, Exchange, Gmail, Hotmail, GMX and Fastmail.
