The email header already supplies the sender's address, the date, and the recipient's address, so you do not retype any of the three. What is left is a subject line, a salutation, a body that states its purpose in the first paragraph, a complimentary close, and a signature block carrying your contact details. The confusion is not yours to apologize for. Search this and half the results teach a paper letter with four competing layouts and one-inch margins, without saying which parts apply to the message sitting unsent in your drafts. Here is what carries over, what disappears, and what email adds that no letter had. ## The four business letter formats, and why only one survives email Writing centers and etiquette guides recognize four standard layouts, and they differ from each other in exactly two ways: whether the first line of each paragraph is indented, and whether the sender's address, date, and complimentary close sit flush left or at the center point of the page. Both are decisions about a sheet of paper — which is why so much of the advice you will find does not apply to an email. ### Full block format Everything is flush against the left margin — sender's address, date, inside address, salutation, body, close, signature. Paragraphs are not indented; a blank line separates them instead. Gallaudet University's writing center describes this as the most common business letter layout, crediting its simplicity and neat appearance, and it is generally treated as the most formal of the four. Nothing is indented and nothing is centered, which is also why it is the only one of the four that arrives in email intact: an email is left-aligned and unindented by default, so you are already writing in full block whether you chose it or not. ### Modified block format The body, salutation, and inside address stay left-aligned, but the sender's address, the date, and the complimentary close are tabbed across to the center point. Paragraphs remain unindented, and Indeed Canada describes it as slightly less formal than full block. The whole distinction is horizontal position on a page, which is precisely what email will not hold: tabbed and centered blocks reflow across mail clients and screen widths, so an email that looks correctly modified-block on your monitor can arrive on a phone as a set of stray, half-indented lines. ### Semi-block format Semi-block follows modified block — date and closing at the center point — and adds a first-line indent to every body paragraph. Sources place it as less formal than full block and slightly more formal than modified block. Its defining feature, that paragraph indent, is the convention email abandoned outright: online, paragraphs are separated by white space, and an indented first line now reads as a typing error rather than a [register](/knowledge/communication/business-formal-email/) choice. ### Indented, or modified semi-block, format All text is left-aligned except the sender's address, date, and closing, body paragraphs are indented, and those elements are usually indented to the same position. Indeed Canada calls it the least formal-looking of the layouts and suggests it for a recipient you know well. It is also the furthest of the four from email practice: the informality it signals through layout on paper is carried in email by the salutation and the sign-off instead. ## Email business letter format: what each part becomes The canonical parts list is stable across sources. The NMU Writing Center gives it as sender's address, date, recipient's (inside) address, salutation, subject line, body, complimentary close, and signature. In email, three of those are handled for you, one is new, and the rest survive with adjustments. **The sender's address, the date, and the inside address** are absorbed by the email header. Your address and the timestamp are attached automatically, and the recipient's address is the line you typed into the To field. Retyping any of the three at the top of a message is the clearest sign of a transplanted form. **The subject line** is the one element email adds that has no letter equivalent, and guidance on business letter format in email consistently advises stating the purpose of the message in a single line. It matters more than it looks because of a difference in commitment: someone who opens an envelope has already decided to read the letter, whereas your subject line decides whether the email is opened at all, when, and with what expectation. **The salutation** keeps its position and loses some of its punctuation, which is involved enough to deserve its own section below. **The body** follows the same three-part shape as the letter: an opening stating why you are writing, the substance, and a close naming the outcome you want or the next step. Keep the paragraphs short — blocks that were tolerable on a page are hard to read in a mail client. **The complimentary close and the signature block** carry the formality the letterhead used to. Guidance on email business letters places your contact details — full name, role, company, phone — beneath the typed name. The formal apparatus that opened the paper letter has not disappeared; it has migrated to the bottom. One category of advice you should actively ignore: Purdue OWL and The Hartford, among others, recommend Times New Roman at 12 points, one-inch margins, and single spacing with a double space between paragraphs. All of it is sound for a printed page and none of it transfers. The recipient's mail client controls how your message renders, and hand-setting a font in an email tends to arrive looking amateur. ## Choosing a salutation and matching your sign-off This is where the two genres genuinely conflict, and where the sources disagree with each other rather than merely differing in emphasis. On punctuation: the business letter convention is "Dear" plus a name and often a title, closed with a colon, while email salutations conventionally take a comma. Instructional Solutions notes that "Hi [Name]," has become the safe default across ordinary business contexts, with "Dear Ms. [Name]:" reserved for legal correspondence, [formal applications](/knowledge/communication/formal-email-writing-examples/), and certain regional or institutional norms. Neither is universally correct, which is the honest answer nobody gives you: the register depends on the recipient, the organization, and what you are asking for. What you can carry from context to context is a rule about consistency. Debrett's records the British convention as matched pairs — "Dear Sir" takes "Yours faithfully," while "Dear Mr Rivers" takes "Yours sincerely." The specific pairing is a national convention, but the principle underneath it travels: your opening and your closing must sit at the same level of formality. "Hi Sarah," followed by "Yours sincerely," reads as two different people writing one email, and that mismatch is more conspicuous than either choice would have been on its own. That gives you a decision you can actually make. Pick the salutation that fits the relationship and the stakes, then choose the sign-off that matches it — the commonly cited ladder runs from "Yours faithfully" and "Yours sincerely" at the formal end, through "Kind regards" and "Best regards," to "Regards" and "Best" at the everyday end. If you cannot read the room, sit one notch more formal on the first message and follow the recipient's lead in the reply. Which leaves the half of this that format cannot settle. Guidance on email business letters repeatedly advises [being concise](/knowledge/communication/to-write-a-concise-email-message/) and staying "you-focused rather than I-focused" — advice that wears a format label but is really about [whose interests the message leads with](/knowledge/influence/how-to-persuade-someone-to-do-something/). A perfectly blocked email that spends three sentences on your own situation and buries the request in the fourth paragraph is correctly formatted and still fails. If your emails are formatted properly but rarely get you what you asked for, the layout was never the variable, and it takes a few minutes to see [how your communication holds up](https://assessment.headwayskills.com/). ## The skills that make formal emails easier to write Read back over the decisions above and notice how few of them are typographic. Where the salutation sits is settled by the medium. What the message asks for, whether the recipient can act on it, and whether the tone fits the relationship are judgments you make each time — and they are why two people using an identical template get different replies. **Communication** covers this territory most directly, and the email guidance inside it is close to what the research keeps arriving at independently: put the main message first, keep the subject line short and informative, send only to the people who need it, and proofread before you send. The judgment that sits above all of it is the choice of medium itself. Writing suits information, documentation, and anything the other person needs time to absorb. A conversation suits complexity, sensitivity, negotiation, and anything still being worked out — and a formal email is often a sign that a conversation was avoided. **Professional Behaviors** is what your formatting choices are actually signaling. Matching your sign-off to your salutation, spelling the recipient's name correctly, being careful about what confidential material belongs in a written record, and writing about colleagues as if they were reading over your shoulder — these register as respect or as carelessness, and they do so before anyone evaluates your argument. Formality is not a fixed setting you get right once; it is read from the situation, which is a thing you learn rather than a thing you are born knowing. **Influence** covers the part the format guides leave out. Most formal emails are an ask — a request, a proposal, an application — and preparation begins with understanding what the recipient gets from saying yes, not with what you need. Rapport before the request, a simple ask, the obvious drawback named rather than hidden, and a follow-up when no reply arrives are what turn a well-formed message into an answered one — done straightforwardly, since the aim is to be credible rather than clever. If one of those three is your actual bottleneck, guessing which is a poor use of the time. The **free Job Skills Test** asks how you handle ordinary situations at work and reports back across twelve such skills, the three above among them, so you can see [which one to build first](https://assessment.headwayskills.com/) instead of rewriting the same email again. ## What this looks like once it is a habit Some of this may already describe how you work — you might soften an opening line, or move a request higher up the message, without ever calling it a skill. Anywhere there is a gap, it is a convention you have not been taught yet rather than a limit on the kind of writer you are, and people close these gaps without changing how they sound. Formal messages also get more consequential rather than less: the higher the stakes and the more senior the recipient, the more a single email is doing on your behalf. You have already done the part most people skip — you checked the convention before sending instead of guessing. What remains is knowing which underlying skill is worth your attention first. ## See where your work skills actually stand You have the format. The useful thing to know next is which skill under it is limiting the emails you send. The **free** Job Skills Test is a short self-assessment of your work skills. You answer questions about how you handle everyday situations at work, and it shows you where you stand across all twelve — the communication habits behind a message like this among them — and which of them will make the biggest difference to you right now. Nothing to prepare, and no wrong answers. **[Take the skills test](https://assessment.headwayskills.com/)** *Free, takes 7 minutes, and your results appear the moment you finish.* ## Who this is for - Professionals building practical workplace skills - Readers looking for specific, usable work advice - Managers, educators, and coaches supporting career readiness ## Common questions ### What is this guide about?
