To write a business email, state your reason for writing in the first sentence or two, keep the body under about 200 words, end with one clear next step, match the greeting and sign-off to your relationship with the reader, give the message a specific subject line, and proofread before sending. That’s the entire formula, and none of it is complicated.
The judgment behind it is what trips people up: how formal is formal enough, how short is too short, and why some emails get answered within the hour while others sit unread. If you’ve ever rewritten the same sentence five times wondering how it will land, that’s normal — almost nobody is formally taught workplace writing. The seven steps below follow the order experienced writers actually work in, which, as you’ll see, is not the order the reader reads in.
How to write a business email in seven steps
Career guides are strikingly consistent about what a business email contains: Indeed and Boise State University’s writing center both describe the same anatomy — subject line, greeting, purpose, next steps, closing, and signature. What the anatomy doesn’t tell you is the writing order. You’ll draft the content first and the subject line almost last, because a subject line is far easier to get right once the email it summarizes exists.
1. Decide what the email is for — one purpose, one email
Before typing anything, name the single thing you want the reader to know or do. One topic per email is the recurring rule across professional-writing guides, and for good reason: a message that asks for three things usually gets an answer to one. Writing your purpose as a plain sentence — “I need Priya’s approval on the revised budget by Friday” — gives you the spine of the whole message. This is also the moment to ask whether email is the right channel at all. Sensitive topics, tangled problems, and anything likely to need real back-and-forth go better in a conversation; the email can follow afterward as a summary and a record.
2. Open the body with your main point
State the reason you’re writing in the first one or two sentences — the request, the update, the question — and let the background follow it. The guides are blunt about why: if the reader has to reach the third paragraph to understand what you need, you’ve already lost some of them. Warming up with context feels polite because that’s how conversation works, but in email it buries the one thing the reader is scanning for. A useful test: could the recipient act on your message from its first two sentences alone? The one exception is a first contact — there, a single sentence saying who you are and why you’re reaching out comes first, and the point follows immediately.
3. Keep the whole message under about 200 words
The step-by-step guides converge on a simple ceiling: most professional emails should stay under roughly 200 words. Short reads as respect for the reader’s time, not as abruptness. Give the text a scannable shape too — paragraphs of two to three lines, bullet points for parallel details like dates or options, and block format, which Boise State’s guide describes as the standard: everything left-aligned, single-spaced, with a blank line between paragraphs. If the message genuinely can’t be brief, that’s usually a sign it’s carrying more than one purpose, or that it belongs in a document or a meeting instead. The politeness lives in the tone, not in the padding.
4. End with one clear next step
Before the sign-off, spell out what should happen next: who does what, by when. “Could you confirm the venue by Wednesday?” gives the reader something they can act on in seconds; “Thoughts?” hands them homework. The guides consistently name an explicit call to action as the mark of an email that gets results — it’s the difference between a message that closes a loop and one that opens a vague one. And if nothing is needed because the email is purely informational, say that too — “No action needed, just keeping you in the loop” — so the reader isn’t left scanning for a hidden request.
5. Match the greeting and sign-off to the relationship
“Dear Ms. Chen” suits a first contact or a formal external message; “Hello” or “Hi” with a first name fits most everyday workplace situations. Indeed’s guidance is to let the greeting reflect your relationship with the recipient — and when you can’t find a name, to address the role instead, as in “Dear Hiring Manager.” Sign-offs run the same spectrum: “Sincerely” at the formal end, “Best regards” or “Kind regards” for daily use, followed by a signature with your full name, role, and contact details so the reader never has to hunt for who you are or how to reach you. When you’re unsure, open one notch more formal than feels necessary; the reply will show you the register the other person prefers, and you can match it from then on.
6. Write the subject line last — short, specific, honest
With the message finished, summarize it in a few words: what it’s about and, when relevant, what’s needed — “Budget approval needed by Friday,” not “Quick question.” Keep it under about 60 characters so it survives a phone screen, and make it concrete: vague subject lines force the reader to open the email just to learn what it wants, and in a crowded inbox that often means it doesn’t get opened at all. A specific subject line keeps working after the email is read, too — it’s what makes your message findable again a month later.
7. Proofread — out loud, and check more than the spelling
Read the finished email aloud once before sending. Reading aloud catches what a silent skim misses: tone that lands colder than you intended, sentences that don’t quite parse, the missing word your brain fills in automatically. Then run the mechanical checks — the recipient’s name spelled correctly, the attachment actually attached if you mentioned one, and the To and Cc fields holding exactly the people who should be there. None of these slips is fatal on its own, but readers quietly treat care in an email as a proxy for care in your work. And if your problem is the opposite one — routine emails costing you twenty minutes of drafting and second-guessing — that friction usually points to a skill you haven’t built yet, not a flaw you’re stuck with, and you can see exactly where you stand instead of continuing to guess.
The skills a good email actually runs on
Seven steps will carry you through your next email. But look at what they quietly demand: judging what your reader needs, striking the right register with people senior to you, making a request without burying it. Those aren’t formatting rules — they’re workplace skills, and every one of them can be practiced.
Communication does most of the work here. Main point first, brief, clear and direct — the habits behind steps 2 through 4 are the core principles of getting a message across at work, and they pay off far beyond email: the same instincts shape how you speak up in a meeting or deliver an update. Part of the skill is also choosing the medium deliberately — knowing which messages belong in writing and which need a conversation — which is exactly the judgment step 1 asks of you. Build this skill and each email stops being a fresh puzzle; the structure becomes something you reach for without thinking.
Professional Behaviors answers the question the steps can’t fully settle: how formal is formal enough? Register, politeness, what’s appropriate to put in writing — these are workplace norms, mostly unwritten, and email is where new professionals meet them first, because a message to a client or a senior manager is often the first impression you make. The encouraging part is that norms are learnable rules, not instincts you either have or lack — nobody is born knowing whether “Hi” is acceptable in a first email — and once you’ve learned to read them, the second-guessing largely stops.
Influence enters because so many business emails are asks — for time, for information, for approval, for a decision. Making a request easy to say yes to — leading with what it means for the reader, keeping the case simple, asking plainly, following up when the answer doesn’t come — is ethical persuasion in written form. It’s what separates the email that gets a same-day reply from the one that’s technically flawless and still ignored.
There’s a faster route than wondering which of the three is your bottleneck: the free Work Skills Test measures all of them — three of the twelve skills it scores — and shows you which one to strengthen first.
None of the seven steps requires talent; that’s the point of a process. If parts of it felt familiar, that’s evidence you’ve already been building these skills without naming them. If a step stung a little — most people recognize themselves somewhere in the twenty-minute draft — that’s simply the next habit to add, and adding a habit doesn’t ask you to become a different kind of writer. One observation worth sitting with: email doesn’t shrink as careers grow. The more responsibility you take on, the more of your judgment reaches people in written form first, which makes this one of the few skills that pays back every single working day — and makes now the cheapest moment to invest in it. Reading a full process to the end instead of grabbing a template is already the less common choice; you’ve done the deliberate part.
Take stock before the next important email
You now have the process; what’s left is knowing your starting point. The Work Skills Test is a free self-assessment of the skills you use at work: it measures you across all twelve — communication, professional behaviors, and influence among them — and ranks where you’re strong and where a little practice would pay off most. Take it before your next important email goes out, and you’ll know whether your real weak spot is the writing itself, the register, or the ask.
Free, and about 7 minutes of your time.
