What this dot point is asking

This outcome is about using email properly and politely. You should be able to compose a message with a clear subject and body, use the To, Cc and Bcc fields correctly, add attachments, and follow email etiquette so your messages are clear, respectful and professional. In the written paper you explain the fields and etiquette and describe sending a message with an attachment; in the practical you may compose and send email.

The answer

The parts of an email

  • To. The main recipients, the people the email is mainly for and who you expect to read or act on it.
  • Cc (carbon copy). People who should see the email for information but are not the main recipients. Everyone can see the Cc names.
  • Bcc (blind carbon copy). Also sends a copy, but Bcc recipients are hidden from the others. Use it to email a large group while keeping everyone's address private.
  • Subject. A short line saying what the email is about, so the reader knows before opening it.
  • Body. The message itself, with a greeting, the content, and a sign-off.

Writing a clear message

A good email has a clear subject (such as "Geography report, class 4A"), a polite greeting, a short and clear message, and a sign-off with your name. Keep it focused: say what you need, give any detail, and be brief. Correct spelling and a respectful tone make a good impression.

Attachments

An attachment is a file sent with the email, such as a report or an image. You add it with the attach option before sending. Two cautions:

  • Check it is attached. It is easy to write "see attached" and forget the file. Confirm it is there before sending.
  • Watch the size. Very large files may fail to send. For big files, compress them or share a cloud link instead.

Email etiquette

Etiquette means polite, sensible behaviour:

  • Use a clear subject and a polite greeting and sign-off.
  • Keep the message clear and respectful; avoid all capitals, which reads as shouting.
  • Reply in good time, and use Reply All only when everyone really needs the reply.
  • Do not forward private messages or addresses without permission.

Examples in context

Example 1. A club newsletter to members. A secretary emails the monthly newsletter to fifty members using Bcc, so every member gets it but no one can see the others' addresses, protecting everyone's privacy. The To field holds only the secretary's own address.

Example 2. A group project update. A student emails the team an update with To for the teammates and Cc for the teacher, who needs to see it for information but is not part of the team. The clear subject and short message let everyone see at a glance what changed.

Try this

  • Cue. State what the To, Cc and Bcc fields are each used for. (To for the main recipients, Cc for visible information copies, and Bcc for hidden copies so recipients cannot see each other.)

  • Cue. Describe how to send a file to someone by email, including one check before sending. (Write the message, use the attach option to add the file, confirm the file is attached and not too large, then send.)

  • Cue. Give two email etiquette points. (Use a clear subject and a polite greeting and sign-off, and keep the tone respectful with correct spelling, avoiding all capitals.)

Original4 marksExplain the difference between the To, Cc and Bcc fields when sending an email, and give one situation where you would use Bcc.

To is for the main recipients, the people the email is mainly for and who you expect to act on it. Cc (carbon copy) is for people who should see the email for information but are not the main recipients; everyone can see the Cc names. Bcc (blind carbon copy) also sends a copy, but the Bcc recipients are hidden, so other recipients cannot see who was put in Bcc.

One situation for Bcc: emailing the same message to a large group, such as a club, while keeping everyone's email address private from the others.

What markers reward: To as the main recipient, Cc as visible information copies, Bcc as hidden copies, and a sensible Bcc situation such as protecting addresses in a group email.

Original4 marksA student needs to email a teacher to hand in a report file. Describe how to write a suitable email and attach the file, and state two etiquette points they should follow.
Show worked answer →

To write and send it: open a new email, type the teacher's address in To, write a clear subject such as "Geography report - [name], class 4A", write a short polite message saying the report is attached, attach the file using the attach option, then send.

Two etiquette points, for example: use a polite greeting and sign-off, and keep the message clear and respectful with correct spelling; also check the attachment is actually attached and not too large before sending.

What markers reward: a clear subject, a polite short message, correctly attaching the file, and two genuine etiquette points such as polite tone, correct spelling, or checking the attachment.
