What is email (electronic mail)?

Blind carbon copy (BCC). If a sender doesn't want their recipient to find out who else received the email, they could use the BCC field to enter those addresses. The addresses in the BCC list don't receive responses when someone presses Reply All.

Attachments. This field contains any files that are attached to the message.

Body

This is the content of the email. It may contain anything the user wishes to send, including text, videos or file attachments. Depending on the email client used, the email body can be formatted in either plain text or HTML. While plain text messages can't contain special formatting or multimedia elements, HTML emails enable special formatting and inclusion of multimedia options within the body of the message. The message body may also include signatures or automatically generated text that the sender's email system inserts.

Uses of email

The following are the most common use cases for email:

• 
  Individual or group communications. Email is a beneficial way to communicate with individuals or small groups of friends or colleagues. It enables users to easily send and receive documents, images, links and other files. It also gives users the flexibility to communicate with others on their own schedule.
  
• 
  Notifications, reminders and follow-ups. Individuals, small groups or organizations can send follow-up emails after appointments, meetings or interviews, or to remind participants of approaching events, due dates and time-sensitive activities. Calendars with the ability to add appointments and events are integrated into most email platforms. These features help users with time management by visualizing the fixed amount of time they have in a day. This enables users to prioritize their decisions and time.
  
• 
  Conveying information to a large group of people. Companies can use email to convey information to a large number of employees, customers and potential customers. Email is frequently used for newsletters, where mailing list subscribers are sent specific, promoted content from a company and direct email marketing campaigns, where an advertisement or promotion is sent to a targeted group of customers.
