Learn to write clear, polite, and effective emails for school, work, and beyond.
The Anatomy of a Professional Email
Every professional email has five key parts. Getting each one right shows that you are organised, respectful, and clear in your communication.
I am writing to let you know that I will be absent from your English class on Friday 14 March due to a family commitment.
Could you please let me know what work I will miss so I can complete it at home? I want to make sure I stay up to date.
Subject Line
Clear, specific topic
Greeting
Polite opening
Body

Sign-off
Polite closing
Signature
Your name + info
Formal vs Informal Emails
The style of your email depends on who you are writing to. Teachers, employers, and people you do not know well require formal emails. Friends and family can receive informal emails.
Formal Email
To a teacher, employer, or official
Subject: Request for extension on science report
Dear Mr Thompson,
I hope this email finds you well. I am writing to request a two-day extension on the science report due this Friday.
I have been unwell this week and have not been able to complete the research section. I would be very grateful if I could submit it by Monday instead.
Thank you for your understanding.
Kind regards,
Sarah Mitchell

Informal Email
To a friend or family member
Subject: Weekend plans?
Hey Jake!
Are you free this Saturday? A bunch of us are going to the beach if the weather's good.
Let me know if you're keen!
Cheers,
Sarah
| Feature | Formal | Informal |
|---|---|---|
| Greeting | "Dear Mr/Ms..." | "Hey!", "Hi!" |
| Language | Full sentences, polite | Relaxed, casual |
| Contractions | Avoid ("I would" not "I'd") | Fine ("I'd", "you're") |
| Sign-off | "Kind regards," "Yours sincerely," | "Cheers," "Talk soon," |
| Emojis | Never | Sometimes OK |
Common Email Mistakes
Avoid these pitfalls that can make your emails look unprofessional or cause misunderstandings.
ALL CAPS = SHOUTING
Writing in all capitals makes it look like you are yelling. "I NEED THIS BY FRIDAY" feels aggressive. Use normal capitalisation.
No Subject Line
Emails without a subject line look like spam and often get ignored. Always include a clear, specific subject.
Text Speak
"hey mr t, can u plz give me the hw? thx" — This is not appropriate for a teacher or any professional email. Write in full sentences.
Reply-All Disasters
Before hitting "Reply All," ask yourself: does everyone on this email need to see my response? When in doubt, reply only to the sender.
Forgetting to Proofread
Always re-read your email before sending. Check for spelling errors, wrong names, and missing attachments.
When to Email vs When to Call or Message
Use Email When...
- ✓ You need a written record
- ✓ The topic is not urgent
- ✓ You need to explain something detailed
- ✓ You want to attach files
Call or Video When...
- ✓ It is urgent or time-sensitive
- ✓ The topic is sensitive or emotional
- ✓ You need a quick back-and-forth
- ✓ Tone might be misunderstood in text
Message/Chat When...
- ✓ It is a quick, simple question
- ✓ You are coordinating with friends
- ✓ The person prefers chat
- ✓ No formal record is needed
Key Vocabulary

Subject: (none)
