Introduction to email

Do you ever feel like the only person who doesn't use email? You don't have to feel left out. If you're just getting started, you'll see that with a little bit of practice, email is easy to understand and use.

In this lesson, you will learn what email is, how it compares to traditional mail, and how email addresses are written. We'll also discuss various types of email providers and the features and tools they include with an email account.

Email advantages

  • Productivity tools: Email is usually packaged with a calendar, address book, instant messaging, and more for convenience and productivity.
  • Access to web services: If you want to sign up for an account like Facebook or order products from services like Amazon, you will need an email address so you can be safely identified and contacted.
  • Easy mail management: Email service providers have tools that allow you to file, label, prioritize, find, group, and filter your emails for easy management. You can even easily control spam, or junk email.
  • Privacy: Your email is delivered to your own personal and private account with a password required to access and view emails.
  • Communication with multiple people: You can send an email to multiple people at once, giving you the option to include as few as or as many people as you want in a conversation.
  • Accessible anywhere at any time: You don’t have to be at home to get your mail. You can access it from any computer or mobile device that has an Internet connection.

Understanding email addresses

To receive emails, you will need an email account and an email address. Also, if you want to send emails to other people, you will need to obtain their email addresses. It's important to learn how to write email addresses correctly because if you do not enter them exactly right, your emails will not be delivered or might be delivered to the wrong person.

Email addresses are always written in a standard format that includes a username, the @ (at) symbol, and the email provider's domain.

The username is the name you choose to identify yourself.

About email providers

In the past, people usually received an email account from the same companies that provided their Internet access. For example, if AOL provided your Internet connection, you'd have an AOL email address. While this is still true for some people, today it's increasingly common to use a free web-based email service, also known as webmail. Anyone can use these services, no matter who provides their Internet access.

Webmail providers

Popular webmail providers are Yahoo!, Microsoft's (previously Hotmail), and Google's Gmail. These providers are popular because they allow you to access your email account from anywhere with an Internet connection. You can also access webmail on your mobile device.

Other email providers and applications

Many people also have an email address hosted by their company, school, or organization. These email addresses are usually for professional purposes. For example, the people who work for this website have email addresses that end with If you are part of an organization that hosts your email, they'll show you how to access it.

Many hosted web domains end with a suffix other than .com. Depending on the organization, your provider's domain might end with a suffix like .gov (for government websites), .edu (for schools), .mil (for military branches), or .org (for nonprofit organizations).

Many companies and organizations use an email application, like Microsoft Outlook, for communicating and managing their email. This software can be used with any email provider but is most commonly used by organizations that host their own email.

Email productivity features

In addition to email access, webmail providers offer various tools and features. These features are part of a productivity suite—a set of applications that help you work, communicate, and stay organized. The tools offered will vary by provider, but all major webmail services offer the following features:
