An email task usually asks for several purposes at once, and leaving one out is a planning problem, not a language problem. The fix is to list the purposes before you write and tick them off as you go.
This page shows the problem in a worked example, then gives a purpose checklist and a revision routine. The writing revision compare view lets you put an omitted-point draft beside a corrected one and see the difference.
What counts as a purpose?
A purpose is something the reader must be able to find in your email: a reason, a suggestion, a question, a request, a piece of information. Tasks signal them with bullet points or sentences starting with a verb such as explain, suggest, ask or invite.
Each purpose needs its own clear sentence. A purpose that is only hinted at is easy for a reader to miss.
Worked example: one purpose falls out
Task. Your friend Aina has invited you to a book fair on Saturday. Write an email to her:
- saying why you cannot go
- suggesting another day
- asking what you should bring
A student’s draft.
Dear Aina, Thank you for inviting me to the book fair. I am sorry but I cannot come on Saturday because I have a family visit. I hope you enjoy it and buy many good books. Maybe we can go together on Sunday afternoon. See you soon, Hui Wen.
The purpose check.
| Required purpose | Covered? | Where |
|---|---|---|
| Why I cannot go | Yes | “because I have a family visit” |
| Suggest another day | Yes | “we can go together on Sunday afternoon” |
| Ask what to bring | No | Nothing in the draft |
The draft is polite and accurate, but one of three purposes is absent. The language is fine, so the student cannot see the gap by checking grammar.
The revision. Add the missing point where it fits naturally:
Maybe we can go together on Sunday afternoon. Also, I would like to bring something to share. What should I bring for the picnic you mentioned?
Now all three purposes are covered, each in its own sentence. The email is only slightly longer.
Notice that the added question refers to the situation (“the picnic you mentioned”) rather than using a general phrase. Specific detail shows the reader you are answering this task.
A planning routine for the exam
- Read the task once for the situation: who is reading and why.
- Underline every required point and number them 1, 2, 3.
- Write a word or two for each beside the number. This is your plan.
- Write the email in the order of your numbers, one sentence or short paragraph per purpose.
- Tick each number as you finish it.
- Read the task again at the end and check each point against your email, not against your memory of it.
Planning takes about a minute. Finding a missing point at step 6 gives you time to add it, whereas finding it after you have put your pen down does not.
Why does this keep happening?
Some writers open with a long thank-you or a personal story and run short of time. If this is you, limit the opening to one sentence and move to the first purpose straight away.
Others read the task once, at the start, and then trust memory. Keep the numbered list visible and use it.
Check yourself
Task. Write to your teacher: (1) apologise for missing Monday’s class, (2) explain why, (3) ask how to catch up.
1. A draft says: “Dear Mr Lim, I am sorry I was absent on Monday. I had a fever. I hope you are well.” Which purpose is missing?
Show answer
Purpose 3. The writer apologised and explained the absence but did not ask how to catch up. Adding “Could you tell me which pages I should read and whether there is any homework?” would complete it.
2. Why is “I hope you are well” not a replacement for the missing purpose?
Show answer
It is polite filler. A purpose is something the task asks you to do, and filler does not do any of the three things listed.
Where to go next
Practise the core habit with cover all requested points in a short email, then repair a real draft with revise an email that omits its main purpose. Use the original email practice afterwards. The full topic is email communication, and the summary selection studio builds the related habit of choosing points by relevance.
A teacher in online one-to-one English as a Second Language tuition can read your plan and your draft side by side and find where a purpose leaves. See the subject learning guide for the wider picture.
