Professional Email Format: Structure, Sign-Offs and 6 Examples

A professional email has seven parts: a specific subject line, a greeting with the person's name, one opening sentence that says why you are writing, a short body with only the context the reader needs, a single clear request, a sign-off, and a signature. Keep it short enough to read on a phone without scrolling, and put the ask where it cannot be missed.

The rest of this guide covers each part, the common mistakes, and six examples you can adapt.

The structure at a glance

Every professional email follows the same skeleton; only the tone changes.

Subject: [Specific topic + action or date]

Hi [First name],

[One sentence: why you are writing.]

[Two to four sentences of context the reader needs.]

[One clear request, with a date if there is one.]

Best regards,
[Full name]
[Role, Company]
[Phone, optional]

Subject line

Write the subject so the reader knows what the email is about and what you need without opening it. Vague subjects such as "Quick question" or "Following up" get skipped or lost in search later.

Weak	Better
Meeting	Moving Thursday's review to 3pm?
Invoice	Invoice 1042 due 15 Nov, PO number needed
Question	Can you approve the Q4 budget by Friday?
Hello	Intro: Sam Lee (Acme) re supplier onboarding

Put the key words first, because phones and narrow inbox panes truncate long subjects. Use "Action needed" or a date only when it is true.

Greeting

Use the person's name and match the formality of your relationship and their industry.

• "Hi Sarah," is the default for most business email, including first contact in many industries.
• "Dear Ms Patel," or "Dear Dr Okafor," for formal contexts: legal, government, academic, or a senior person in a conservative sector.
• "Hello team," or "Hi all," for groups.
• Avoid "To whom it may concern" when a name can be found, and "Hey" with people you do not know.

If you do not know the name, a minute of research usually finds it. Our guide to finding someone's business email covers where names and addresses are published.

Opening line

State your purpose in the first sentence. The reader decides in a few seconds whether to deal with your email now or later.

• "I'm writing to confirm the delivery date for order 5512."
• "Could you review the attached proposal before Friday's call?"
• "Jane Smith suggested I contact you about your supplier onboarding."

"I hope this email finds you well" is not wrong, but it pushes the purpose down a line. If you use a pleasantry, keep it short and specific to the person.

Body

Include only the context the reader needs to act, in paragraphs of two or three sentences.

• One topic per email. Two unrelated requests in one message means one gets forgotten.
• Lead with the conclusion, then the reasons.
• Use a short bulleted list for three or more items, dates or options.
• Put long detail in an attachment or link, and say what it contains.
• Use plain words. "Use" rather than "utilise", "about" rather than "with regard to".

The request

End the body with one clear, answerable request, ideally with a date.

Vague	Clear
Let me know your thoughts.	Can you confirm by Wednesday whether option A or B works?
Happy to chat sometime.	Are you free for 20 minutes on Tuesday or Thursday afternoon?
Any update?	Is the contract still on track for signature this week?

If no reply is needed, say so: "No need to reply; this is just for your records."

Sign-off

Choose a sign-off that matches the greeting's tone.

• Formal: Kind regards, Best regards, Yours sincerely (UK, when you used their name in a formal letter-style email).
• Neutral: Best, Thanks, Many thanks.
• Avoid: Cheers in very formal contexts, "Sent from my phone" as your only sign-off, and stacked sign-offs such as "Thanks, Best regards".

Signature

A signature should tell the reader who you are and how else to reach you, in four lines or fewer.

Keep it as text rather than one large image, which may not load and cannot be copied. Skip inspirational quotes and long legal disclaimers unless your company requires them.

Six examples

Adapt these by changing the specifics, not the structure.

1. Requesting a meeting

Subject: 20 minutes next week on the warehouse move?

Hi Daniel,

I'd like to walk you through the timeline for the warehouse move before we confirm dates with the landlord.

It should take 20 minutes. Would Tuesday at 10am or Thursday at 2pm suit you?

Best regards,
Sarah

2. Following up after no reply

Subject: Re: Proposal for Q1 training

Hi Marta,

Following up on the proposal I sent on 3 November. Is a decision still expected this month, or should I check back in January?

Thanks,
Sam

Keep follow-ups shorter than the original and give an easy way to answer. For cold outreach, see our follow-up sequence guide.

3. Introducing two people

Subject: Intro: Priya (Brightline) <> Tom (Harbour Analytics)

Hi Priya and Tom,

Priya runs operations at Brightline and is looking for help with demand forecasting. Tom's team at Harbour built exactly that for two retailers I know well.

I'll let you take it from here.

Best,
Sam

4. Declining politely

Subject: Re: Speaking at the November meetup

Hi Leo,

Thank you for the invitation. I can't commit to November, but I'd be glad to be considered for the spring event.

Kind regards,
Nadia

5. Sending a document for approval

Subject: Approval needed: Q4 budget by Friday 14 Nov

Hi Grace,

The Q4 budget is attached. Total spend is unchanged; I've moved £4,000 from events to contractors, explained on page 2.

Could you approve or send comments by Friday?

Thanks,
Omar

6. A first cold email to a prospect

Subject: Delivery delays at your Leeds depot

Hi Chris,

I saw Northfield opened a second depot in Leeds this spring. We help logistics firms cut failed first-time deliveries, and teams your size typically come to us after a new site goes live.

Worth a 15-minute call to see if it applies to you?

Best regards,

For cold email, the format is the easy part. The address has to be right too: a misspelt or dead address bounces, and repeated bounces hurt the domain you send from. You can check an address free with the email verifier before sending. And despite what lists of "spam words" suggest, wording is rarely why mail lands in spam; authentication and reputation matter more.

Common mistakes

• Burying the ask in the third paragraph.
• Reply-all when only one person needs the answer.
• Attachments without explanation of what they are and what to do with them.
• Inconsistent names: check spelling, especially in the greeting.
• Sending angry. Write the draft, wait, then edit.

The takeaway

Subject that says what you need, greeting with a name, purpose in the first line, short body, one clear request, consistent sign-off, and a four-line signature. Get those right and the tone is easy to adjust for any situation.
