Most low scores on the TOEFL email task come from a small set of repeated mistakes: skipping a required point, misjudging tone, and rushing the final check. None of these require better vocabulary to fix — they require a more disciplined process in the 7 minutes you have.

Mistake 1: Implying instead of stating a point

Weak: "I had some trouble with the schedule this week."
Fixed: "I would like to request a two-day extension on the assignment due to a scheduling conflict with my part-time job."

The weak version hints at a problem without asking for anything. Purposeful Communication requires you to state the request directly, not describe a situation and hope the reader infers what you want.

Mistake 2: Tone mismatch with the recipient

Weak (to a professor): "Hey, can you just push the deadline back? Kinda busy rn."
Fixed: "Dear Professor Kim, I am writing to ask whether a short extension on the assignment would be possible, as I am managing an unusually heavy week."

Tone is scored independently of coverage. A message that reaches a professor with casual slang loses marks under Social Conventions and Tone even if the request itself is clear.

Mistake 3: No time left to proofread

Writers who spend all 7 minutes typing often submit with an unfinished sentence, a wrong name, or a tone slip in the closing line that a 30-second reread would have caught. Reserve time deliberately — see timing for the 7-minute task.

Mistake 4: Overly long or padded responses

Adding extra sentences to "sound more complete" often introduces new grammar errors and dilutes the tone instead of strengthening the response. Most complete responses run 80–120 words — see how many words a TOEFL email should be.

Mistake 5: Generic greetings and closings

Weak: "Hello, [no name]... Thanks."
Fixed: "Dear Professor Alvarez, ... Sincerely, [Your name]"

Using the name given in the prompt and a closing that matches the register signals attention to the social context, which is exactly what this criterion measures.

Coverage Are all three required points stated directly?
Tone Does the greeting and closing match the recipient?
Language Any obvious grammar slips in the final read?
Length Roughly 80–120 words, no unnecessary padding?

Why these five mistakes repeat so often

All five mistakes above share a root cause: they happen when a writer moves straight from reading the prompt to typing, without a brief planning step. Labeling the three required points, checking the named recipient's formality, and reserving time to reread are all quick habits, but skipping any one of them under time pressure is what produces these patterns again and again. Building the habit matters more than memorizing the list — once the process is automatic, these specific mistakes mostly disappear on their own.

How grading actually catches these patterns

Each of these mistakes maps to one of the three scored criteria, which is why they're worth fixing individually rather than treating "do better" as one vague goal. Missing or vague points affect Purposeful Communication. Tone mismatches and generic greetings affect Social Conventions and Tone. Rushed proofreading mostly surfaces as Language Facility errors — the kind of small grammar slips that a calmer, more careful writer would have caught. Thinking about mistakes by criterion, rather than as one undifferentiated pile of "errors," makes it much easier to target practice where it counts.

Try this yourself

Write a response to a campus-email prompt, then run it against this checklist before you would submit. Confirm your self-check with the TOEFL email checker, which flags coverage, tone, and language issues automatically.

Frequently asked questions

Which mistake costs the most points?

Missing a required point usually costs the most, because it affects Purposeful Communication directly and caps the overall task score regardless of how polished the rest of the email is.

Can one grammar mistake ruin my score?

No. Language Facility looks at overall clarity and control, not a single error. Isolated slips rarely sink an otherwise strong response.

How do I know if my tone is wrong?

Compare your greeting and closing against the recipient named in the prompt: a professor or administrator needs formal language; a classmate can be addressed more casually.
