What's the Right Way to Write an Email on the TOEFL 2026?

You see a short prompt — maybe 40 words about a neighbor's noisy dog, or a coworker organizing a team event. You have 7 minutes to write an email responding to it. Simple, right? Then why do so many test-takers struggle with this task?

The Write an Email task on the TOEFL iBT 2026 Writing section tests a skill most English proficiency exams have ignored: practical, everyday written communication. It's not about academic argumentation or literary analysis. It's about writing a clear, appropriate, well-organized email that addresses everything the prompt asks for.

This task rewards students who can read carefully, judge the appropriate register, organize their thoughts quickly, and write naturally. Here's everything you need to know to do it well.

The Task Format

The Write an Email task gives you:

1. A short prompt — typically 35 to 55 words describing a situation. This might be a message from a friend, a coworker, a neighbor, a landlord, or a service provider.
2. Three required details — specific points you must address in your response. These are listed as bullet points.
3. Instructions — telling you to write an email that responds to the situation and covers all three details.
4. 7 minutes — to read the prompt, plan your response, write it, and review it.

The prompt provides an email header: who you're writing to (emailTo) and a subject line (emailSubject). If the recipient is addressed by first name, the tone is informal. If the recipient is addressed by their full name or email address, the tone is formal.

What the Prompt Looks Like

Here's the general structure:

"You will read some information. Then you will write an email response."

The information describes a situation — maybe your apartment building is renovating the lobby, or a friend invited you to a weekend trip, or your supervisor asked for feedback on a new schedule. Below the situation, three bullet points tell you what to include:

• Describe your reaction or experience
• Evaluate or comment on something specific
• Suggest an action or make a request

These three details typically follow a pattern: describe, evaluate, act. The first asks for description or context, the second asks for your opinion or assessment, and the third asks you to propose something or request something.

Register Judgment: Formal vs. Informal

The most critical skill this task tests — beyond basic writing ability — is register judgment. Can you tell whether this email should be formal or informal, and can you write consistently in that register?

How to Determine the Register

Informal signals:

• The recipient is addressed by first name ("Hi Sarah")
• The situation involves a friend, neighbor, or casual acquaintance
• The prompt describes a personal or social situation (a party, a trip, a shared hobby)

Formal signals:

• The recipient is addressed by email address or title ("Dear Dr. Martinez" or "[email protected]")
• The situation involves a workplace, institution, or professional context
• The prompt describes a business, administrative, or professional situation

What Register Looks Like in Practice

Informal email:

Hi Sarah,

Thanks for the invite! I'd love to come to the barbecue this weekend. I've actually been looking for a chance to try that new burger recipe I found...

Formal email:

Dear Dr. Martinez,

Thank you for informing the tenants about the upcoming renovation. I appreciate the advance notice and would like to share some concerns regarding the proposed timeline...

The same ideas — expressing interest, sharing concerns — sound completely different depending on register. Using "Thanks for the invite!" in a formal email to your building manager sounds wrong. Using "I would like to express my gratitude for this opportunity" in a casual email to a friend sounds equally wrong.

Common Register Mistakes

Mixing registers. Starting formally ("Dear Mr. Chen, I am writing to inform you...") and then switching to casual ("Anyway, just let me know what works!"). Pick one register and maintain it throughout.

Defaulting to formal. Many test-takers play it safe by writing everything formally. But if the prompt clearly describes a friend or casual relationship, an overly formal tone sounds unnatural and may cost you points for inappropriate register.

Overcasual writing. Abbreviations like "u" (for "you"), "gonna," "btw," or excessive exclamation marks don't belong even in informal emails. Informal doesn't mean texting.

Email Structure

A strong email response follows a clear structure:

Opening (1-2 sentences)

Acknowledge the situation described in the prompt. This shows you've read and understood the context.

• Informal: "Great to hear about the event! I was just thinking about..."
• Formal: "Thank you for your message regarding the schedule change. I have reviewed the proposal and..."

Body (3-4 paragraphs or sections)

Address all three required details, giving each one enough development to show thoughtful engagement. Don't just list answers — connect them naturally.

Each detail should get at least 2-3 sentences. Simply writing one sentence per detail will result in a response that feels thin and underdeveloped.

Closing (1-2 sentences)

End with an appropriate sign-off that matches the register.

• Informal: "Let me know what you think! Looking forward to it."
• Formal: "Please do not hesitate to contact me if you need any further information. I look forward to your response."

Addressing All Three Details

This is where many test-takers lose points: they cover two details thoroughly but forget or barely mention the third. The scoring rubric specifically checks whether all three required points are addressed.

Strategy: Number Them

Before you start writing, mentally number the three details. As you write, make sure each one gets its own section or paragraph. After finishing, do a quick scan: detail 1 — covered? Detail 2 — covered? Detail 3 — covered?

How Much to Write for Each Detail

The three details usually follow the "describe, evaluate, act" pattern. Here's how much to write for each:

Detail 1 (Describe): 2-3 sentences describing your experience, reaction, or the relevant context. Be specific — don't just say "I liked it." Say what you liked and why.

Detail 2 (Evaluate): 2-3 sentences giving your opinion, assessment, or feedback on something specific. Support your opinion with a reason or example.

Detail 3 (Act): 2-3 sentences proposing an action, making a request, or suggesting a solution. Be concrete — don't just say "we should do something." Say what you think should be done.

Appropriate Length: 150-220 Words

The email should be long enough to fully address all three details but short enough to be completed in 7 minutes. A response of 150-220 words is the sweet spot.

Under 120 words: Your response is probably too thin. You've likely skipped a detail or given underdeveloped answers. This typically scores Band 3 or below.

120-150 words: Adequate but tight. You've addressed all details but may not have developed them fully.

150-220 words: Ideal range. Enough space to address all three details with specific examples and natural development.

Over 250 words: You're likely overwriting. This can lead to repetition, off-topic tangents, or running out of time for proofreading. More is not always better.

Tone and Conventions

Email Conventions to Include

• Greeting — "Hi [Name]," or "Dear [Name],"
• Sign-off — "Best," "Thanks," "Regards," or "Sincerely,"
• Your name — Even a first name at the end signals email format awareness

These small touches show that you understand email as a communication format, not just a writing exercise.

Tone Tips

Be natural. Write as you would in a real email, not as you would in an essay. Emails are direct and conversational, even formal ones.

Show personality (informally). In an informal email, it's appropriate to express enthusiasm, humor, or casual concern. "That sounds amazing!" is fine. "I am pleased to hear of this development" is stiff.

Be professional (formally). In a formal email, be polite but direct. Don't be obsequious ("I humbly request your most gracious consideration"). Just be clear and courteous.

Avoid hedging excessively. "I think maybe perhaps it might be a good idea to possibly consider..." is weak. "I'd suggest..." is confident and clear.

Common Mistakes That Cost Points

Mistake 1: Not Reading the Prompt Carefully

The prompt is only 35-55 words. Read every word. Students sometimes misunderstand the situation — writing to the wrong person, addressing the wrong topic, or misinterpreting the relationship. Five seconds of careful reading prevents five minutes of writing the wrong email.

Mistake 2: Ignoring One of the Three Details

This is the most common scoring penalty. You must address all three bullet points. If you write a beautiful email that only covers two of them, your score will suffer significantly.

Mistake 3: Writing an Essay Instead of an Email

Emails have a different structure than essays. They don't have thesis statements, topic sentences, or formal conclusions. They have greetings, direct communication, and sign-offs. If your response reads like a five-paragraph essay, it doesn't demonstrate email-writing competence.

Mistake 4: Spending Too Long Planning

With only 7 minutes total, you can't afford to spend more than 60-90 seconds planning. Read the prompt, identify the three details, determine the register, and start writing. Your plan doesn't need to be elaborate — a mental note of what to cover is sufficient.

Mistake 5: Not Leaving Time to Proofread

Reserve the last 30-60 seconds for a quick review. Check for obvious grammar errors, missing details, and register consistency. Even catching one or two mistakes can improve your score.

The 7-Minute Timeline

Here's a practical breakdown of how to use your 7 minutes:

This timeline is flexible. Some writers plan faster and write slower; others jump straight into writing. The non-negotiable parts are: read carefully at the start, and proofread at the end.

What Separates Band 3 from Band 5

Understanding the scoring criteria helps you write strategically:

Band 3 Response (Weak)

• Addresses only 1-2 of the three details
• Unclear or inconsistent register
• Limited vocabulary — uses the same basic words repeatedly
• Grammatical errors that sometimes obscure meaning
• Very short (under 100 words) or poorly organized
• Missing email conventions (no greeting, no sign-off)

Band 4 Response (Adequate)

• Addresses all three details, but some are underdeveloped
• Generally appropriate register with minor slips
• Adequate vocabulary with some variety
• Some grammatical errors that don't obscure meaning
• Reasonable length but could be more developed

Band 5 Response (Strong)

• Addresses all three details with specific, relevant development
• Consistent and appropriate register throughout
• Varied vocabulary and natural phrasing
• Few grammatical errors, and none that affect comprehension
• Appropriate length (150-220 words) with clear organization
• Proper email conventions and natural tone

The jump from Band 3 to Band 5 isn't about writing more — it's about writing more specifically and more naturally.
