How to Write a Professional Email (Format, Examples & Templates)

A professional email has six parts: a clear subject line, a greeting, a one-line purpose, a short body, a sign-off, and a signature. Get those in order and almost any email — a request, a follow-up, an introduction — reads as polished and gets a faster reply. Most email problems come from skipping one of the six or burying the point three paragraphs down.

Here’s the format, an annotated example, and templates for the emails people write most.

The professional email format

Part	What it does	Example
Subject line	Tells them what it’s about before they open	“Quick question about the March invoice”
Greeting	Sets the tone	“Hi Dana,”
Purpose (first line)	States why you’re writing, immediately	“I’m following up on the proposal I sent last week.”
Body	The detail, kept short	1–3 tight paragraphs
Sign-off	Closes politely	“Best regards,”
Signature	Says who you are and how to reach you	Name, title, company, contact

Write the subject line last (but put it first)

The subject line decides whether your email gets opened. Make it specific and short — 4 to 8 words that name the topic and, ideally, the action.

• ❌ “Hi” / “Question” / “Following up”
• ✅ “Invoice #2043 — can you confirm by Friday?”
• ✅ “Intro: Sarah (design) ↔ Marcus (eng)”

A good trick: write the email first, then summarize its purpose into the subject.

Match the greeting to the relationship

• Formal / first contact: “Dear Ms. Rivera,” or “Dear Hiring Manager,”
• Standard professional: “Hi Jordan,” or “Hello Jordan,”
• Familiar / internal: “Hi Jordan,” or “Hey team,”

Avoid “To whom it may concern” (dated) and “Hey” for someone you don’t know. When you can’t find a name, “Hi there,” is a safe modern default.

Lead with your purpose

The single biggest upgrade to most work email: say why you’re writing in the first sentence. Readers skim. If the point is in paragraph three, they may never reach it.

Hi Dana,

I’m following up on the March invoice (#2043) — I want to make sure it’s on track for Friday. Could you confirm it’s been approved on your end?

Notice the whole ask is clear in two lines.

Keep the body short and scannable

• One idea per paragraph, two to three sentences each.
• Use a bulleted list for multiple questions or steps — it’s far easier to answer.
• Bold the one thing you need if the email is longer.
• End the body with a clear next step: what you want, and by when.

End with a sign-off and a real signature

Close with a short sign-off — “Best regards” is the safe default — then your signature block. For the full list of closings and when to use each, see how to end an email.

Your signature is the part people underrate. It’s how the reader knows who you are, what you do, and how to reach you without hunting. A clean, consistent signature makes even a two-line email look professional. Browse signature examples by role or copy a template.

A full annotated example

Subject: Proposal follow-up — decision by Thu?

Hi Priya,

I’m checking in on the website proposal I sent last Tuesday. To keep the timeline we discussed, I’d need a go/no-go by Thursday.

Two quick things that might help you decide:

• The quoted price holds through the end of the month.
• I can start the week of the 14th if we’re a go.

Happy to hop on a 15-minute call if that’s easier. Thanks for taking a look!

Templates for common emails

Follow-up:

Hi [Name], following up on [topic] from [when]. Is there anything you need from me to move this forward? Happy to help. Best,

When you’re away, close the loop

A professional presence includes what happens when you can’t reply. A clear out-of-office message keeps things moving while you’re out — grab a ready-made one from our out-of-office message examples.

Make your whole team’s email look professional

Individual habits get you far, but for a company, consistency is what signals professionalism at scale — and the signature is the most visible, most inconsistent part. Firma lets you design one on-brand signature and deploy it across every Gmail and Google Workspace account, so every email your team sends ends on the same polished note. See how it works.
