How to Write a Professional Email: Structure, Tone Ladder and Six Templates

AdeptWrite Editorial TeamUpdated 11 min read

A professional email has six parts: a specific subject line, a greeting, the purpose in the first sentence, only the details the reader needs, one clear action with a date, and a polite sign-off with your name. Match the tone to the relationship, keep it short enough to read on a phone, and proofread before you send.

The short answer

Write the subject line so it says what the email is about, open with the reason you are writing, give the facts the reader needs, say exactly what you want them to do and by when, and close politely with your name. If someone reads only the first two lines, they should still know why you wrote.

That is the whole method. The rest of this guide shows each part, how formal to sound, six annotated templates, and a checklist to run before you press send.

The six parts of a professional email

PartWhat it doesExample
1. Subject lineTells the reader what this is and what you needQuestion about the Q3 budget: reply needed by Friday
2. GreetingSets the level of formalityDear Ms Alvarez, / Hi Sam,
3. Purpose lineStates why you are writing, in one sentenceI am writing to ask whether we can move Thursday's review to 2 pm.
4. DetailsGives only the context needed to actShort paragraphs, a list if there are several items
5. ActionSays what you need, from whom, by whenCould you confirm by Wednesday 11 November?
6. Sign-offCloses politely and identifies youKind regards, Priya Nair, Operations Coordinator

1. Write a specific subject line

The subject line decides whether the email gets opened and whether it can be found later. Name the topic and, if there is one, the deadline or the action.

  • Weak: "Question" or "Hello" or "Quick favour"
  • Better: "Invoice 2041: payment status"
  • Better: "Request: two days of leave, 17-18 December"
  • Better: "Introduction: Dana Kim (design) and Luis Ortega (marketing)"

Keep it short enough to show in full on a phone, which in practice means a handful of words with the key term first. Avoid capital letters throughout, exclamation marks and words such as "URGENT" unless it truly is. For more patterns, see email subject lines.

2. Choose the greeting

Match the greeting to the person, not to a rule.

  • A person you do not know, a senior person, or a formal setting: "Dear Dr Rivera," or "Dear Ms Alvarez,"
  • A colleague you work with regularly: "Hi Sam," or "Hello Sam,"
  • A group: "Hello team," or "Hi everyone,"
  • If you do not know the name: try to find it first. If you cannot, "Dear hiring team," is better than "To whom it may concern". See to whom it may concern for alternatives.

Use the name the person uses in their own email signature. If you cannot tell a title, "Dear Alex Morgan," with the full name is a safe, neutral option. More options are in how to start an email.

3. Put the purpose in the first sentence

Do not open with "I hope this email finds you well" and then wait three lines to make your point. A short courtesy is fine between people who know each other, but the purpose should arrive immediately.

  • "I am writing to confirm the delivery date for order 4417."
  • "Following our call this morning, here is the summary and the next step."
  • "I would like to ask for a one-week extension on the project report."

4. Give only the details the reader needs

Ask yourself what this person must know to act. Include that; leave the rest out.

  • Keep paragraphs to two or three sentences.
  • Use a short bulleted or numbered list for three or more parallel items such as dates, documents or questions.
  • Put dates in an unambiguous form: "Wednesday 11 November", not "10/11", which reads as 10 November in the UK and 11 October in the US.
  • Mention attachments in the text ("I have attached the signed form") and check they are actually attached.

5. State the action and the date

An email that asks for nothing rarely gets a reply, and an email that asks vaguely gets a vague reply. Say who should do what and by when.

  • Vague: "Let me know your thoughts."
  • Clear: "Could you approve the draft by Thursday 12 November so it can go to print on Friday?"

If you have more than one request, number them. People answer numbered questions one by one.

6. Sign off and add a signature

End with a closing line, a sign-off, a comma and your name. "Kind regards" and "Best regards" work almost everywhere; "Thanks" suits a quick request. Add a signature block with your full name, role, organisation and one way to reach you. The full list of options is in how to end an email.

A tone ladder: from very formal to friendly

The same message can be written at several levels. Pick the rung that matches your relationship with the reader, and when in doubt go one step more formal than you think you need for a first contact.

LevelGreetingSample sentenceSign-off
Very formalDear Professor Okonkwo,I would be grateful if you could consider my request.Yours sincerely,
FormalDear Ms Alvarez,I am writing to ask whether you could review the attached proposal.Kind regards,
Professional, neutralHello Ms Alvarez,Could you review the attached proposal by Friday?Best regards,
Friendly professionalHi Maria,Would you have time to look at the attached proposal this week?Thanks,
Casual (colleagues you know well)Hi Maria,Can you take a look at this when you get a chance?Cheers,

Contractions ("I'd", "we're") are normal from the middle rung down and best avoided in the first two. If you are unsure about a draft, the Tone Changer has Formal, Office and Casual modes that rewrite your text at a different level. Treat the output as a suggestion to edit, because it is generated text and you are the one who signs it.

Six annotated templates

Swap the names, dates and order numbers for your own. The notes underneath each template explain why the lines are there.

Template 1: a request

Subject: Request: access to the sales dashboard by Friday

Dear Mr Hughes,

I am writing to ask for access to the monthly sales dashboard. I joined the regional team on 3 November and need it to prepare the Q4 forecast.

Could you grant access to p.nair@northwind.example by Friday 13 November? If another form is needed, please tell me and I will complete it today.

Thank you for your help.

Kind regards, Priya Nair

The subject carries the ask and the date. The second paragraph gives the reason, which makes it easy to say yes. The offer to complete a form removes a possible delay.

Template 2: an introduction

Subject: Introduction: Dana Kim and Luis Ortega

Hello Dana and Luis,

I would like to introduce you to each other. Dana leads product design at Northwind; Luis runs partnerships at Northwind. You are both planning a customer research project for the new year, and I think a conversation would save you both time.

I will leave it to you to find a time that suits you both. Thank you both for being open to this.

Best regards, Priya Nair

A good introduction says why each person might want to meet and then steps back. Ask permission from both people first when you can.

Template 3: a status update

Subject: Project update: website redesign, week of 9 November

Hi team,

The redesign is on track for the 5 December launch. Here is where we are:

- Done: homepage and pricing layouts approved - In progress: checkout copy, due Wednesday - Needs a decision: whether to keep the old blog URLs (see question below)

Decision needed from Ms Alvarez by Thursday: should we redirect the old blog URLs or retire them?

Thanks, Priya Nair

Lead with the status in one sentence, then list. Put the one decision you need where it cannot be missed.

Template 4: a complaint

Subject: Order 88213 arrived damaged: replacement requested

Dear Customer Support,

I am writing about order 88213, delivered on 6 November. The glass shade in the box was cracked, and I have attached two photographs.

I would like a replacement. If that is not possible, please tell me how to arrange a refund. I would appreciate a reply by Monday 16 November.

Kind regards, Priya Nair Order email: p.nair@northwind.example

State the facts, the outcome you want and a date. Stay calm and specific; a polite complaint is the one most likely to be solved.

Template 5: a thank-you

Subject: Thank you for your help with the audit

Dear Ms Alvarez,

Thank you for staying late on Tuesday to help me find the missing invoices. Because of that, we could close the audit on time.

I really appreciate it.

Best regards, Priya Nair

Name the specific thing the person did and its result. A thank-you needs no request, so do not add one.

Template 6: a follow-up

Subject: Following up: proposal sent 4 November

Hi Jordan,

I wanted to follow up on the proposal I sent on 4 November. Do you have any questions I can answer?

If it helps, I can walk through it in a 15-minute call this week. Otherwise, could you let me know by Friday whether you would like to go ahead?

Thanks, Priya Nair

Refer to the earlier email by date, keep it short and offer an easy next step. More examples are in how to write a follow-up email.

How long should a professional email be?

There is no fixed number, but a useful rule is that the main message should fit on one phone screen without scrolling. Many people read work email on a phone, so:

  • Put the purpose and the action in the first few lines.
  • Use short paragraphs with a blank line between them.
  • Avoid long attachments-as-body; summarise the key points and attach the rest.
  • If you need more than about three short paragraphs, consider whether a call or a document would serve better.

To see how long a draft is, paste it into the Word & Character Counter or the Reading & Speaking Time Calculator. Both run in your browser.

Writing to colleagues in other countries

Email norms differ across cultures, and the same sentence can sound brusque in one place and over-polite in another. A few habits help when you write across borders:

  • Directness. Some workplaces expect the request in the first line; others expect a few polite sentences first. If you do not know the reader, state the purpose early but add one courteous line, such as thanking them for their time.
  • Titles. In many countries, academic and professional titles matter. Use "Dr" or "Professor" until invited to use a first name, and copy how the other person signs.
  • Time zones. Write the time with its zone, such as "10:00 GMT" or "2 pm Eastern Time", and give the date in words. Where possible offer a time in both locations.
  • Spelling. Choose American or British spelling to match the reader and stay consistent: "organization" or "organisation". See British vs American spelling for the main patterns.
  • Idioms. Phrases such as "touch base" or "ballpark figure" may confuse readers who use English as a second language. Plain words travel better.
  • Dates and numbers. Use "12 November 2026" rather than numerals only, and state the currency.

Common mistakes in professional emails

Forgetting the attachmentAttach before you write the body, or check the text for the word "attached"
Writing while angryDraft, wait, then edit before sending
Sending sensitive information in the bodyUse your organisation's approved secure method

A pre-send checklist

  1. Does the subject line say what the email is about?
  2. Is the greeting right for this person, and is the name spelled correctly?
  3. Does the first sentence state the purpose?
  4. Is every sentence needed by the reader?
  5. Is the requested action, and its date, clear?
  6. Are the attachments there and the links working?
  7. Is the tone right for the relationship?
  8. Did I check spelling and grammar?
  9. Are the right people in To, CC and BCC?
  10. Does the signature give my name, role and a contact?

Using AdeptWrite to prepare an email

The Email & Letter Writer can draft a first version in three modes: Formal letter, Job application and Follow-up. Give it the facts and edit the result, adding the names, dates and details yourself, because generated text can miss context that only you know.

Before you send, paste the text into the Grammar Checker to catch grammar and punctuation slips, and the Spell Checker to match American, British or Australian spelling to your reader. If the draft sounds stiff or too casual, try the Tone Changer. Free use is limited to 6,000 characters per run, which is enough for almost any email.

Frequently asked questions

What is the correct format for a professional email?

Use a specific subject line, a greeting that fits the relationship, a first sentence that states your purpose, short paragraphs with only the necessary details, a clear request with a date, and a sign-off such as "Kind regards," followed by your name and a signature with your role and contact details.

How do I start a professional email?

Begin with a greeting such as "Dear Ms Alvarez," or "Hi Sam," depending on how well you know the person, then state your reason for writing in the first sentence. If you have no prior contact, add one polite line about who you are before the request.

How long should a professional email be?

Keep it short enough to read on a phone screen without much scrolling: purpose and request in the first lines, then a few short paragraphs at most. If you need much more, put the detail in an attachment or switch to a call, and summarise the key point in the email.

Is it okay to use "Hi" in a professional email?

Yes, in most workplaces "Hi" followed by a first name is fine for colleagues and for people who have written to you informally. For a first contact with a senior person, a client in a formal industry or an official body, start with "Dear" and the title and surname.
