How to Write a Professional Business Email (With 15 Examples)

Writing a professional business email doesn't have to be stressful. Whether you're reaching out to a new client, following up after a meeting, or sending a cold pitch, the right email can open doors.

The 5-Part Structure of Every Great Business Email

1. Subject Line — Clear, specific, and under 50 characters
2. Greeting — Professional but warm ("Hi [Name]," or "Dear [Name],")
3. Opening Line — State your purpose immediately
4. Body — Keep it concise, use short paragraphs, include a clear ask
5. Closing — Professional sign-off with your full signature

The Four Things Every Business Email Has to Do

Whatever the situation, a professional email is doing the same four jobs. When one is missing, the reader has to work to figure out what you want, and that work is what turns into a delay.

1. Establish who you are and why you are writing, in the first sentence.
2. Supply exactly the context needed to act — and no history beyond it.
3. Make one clear request. Two requests halve your odds on both.
4. Name the next step and a date.

Write the Subject as a Summary

Most business mail is triaged from the subject and the first preview line. A subject that summarizes — "Invoice 2026-014: which PO number should I use?" — gets acted on. A subject that labels — "Question" — gets postponed. This one change does more for response rates than anything you do to the body.

Structure for a Phone Screen

Assume the reader sees about fifteen lines before scrolling. Put the ask above that line. Move background below it, clearly marked so it can be skipped. If your message genuinely needs a page of detail, that detail belongs in an attachment with a one-line summary in the body.

Tone: Plain, Warm, and Unhedged

The two failure modes are over-softening and over-clipping. "I was just wondering if you might possibly have a moment" signals that you expect to be ignored. A three-word reply to someone you have never met reads as brusque. The reliable middle is one line of warmth and then the point: "Hope the week is going well. I need one thing — the signed W-9 — by Thursday so I can get you into the payment run."

The Situations Worth Having a Version Of

• Introducing yourself to someone who has never heard of you
• Following up after no reply — first, second, and final
• Sending a quote or proposal, with a decision date
• Confirming a meeting, and what to bring
• Asking for a document, an introduction, or a reference
• Requesting payment, at friendly, firm, and formal stages
• Declining work without closing the door
• Apologizing for a real mistake, briefly and with a fix
• Announcing a price or policy change
• Closing a project and asking for the referral

Formatting That Gets Read

• Short paragraphs. Three sentences is a long one.
• A list wherever you would otherwise write "first... second... third."
• Bold for the deadline and the ask, and nothing else — bold everywhere is bold nowhere.
• A signature with a name, a role, a business name, one number you answer, and one link.

The Habit That Prevents Most Problems

Write anything sensitive, save it, and reread it in the morning. The second version is always shorter, always calmer, and always works better. And do not put anything in email you would not want read aloud later — business email is forwardable, discoverable, and permanent.

Before You Send

• Exactly one ask, with a date attached?
• Subject line summarizes rather than labels?
• Names and company spelled the way they spell them?
• The attachment actually attached?
• Correct recipients — and is anyone on CC who should be on To?
