Writing business letters that get a straight answer, not silence
Business letters: when the letter form earns its effort, the six parts every one contains, three openings that work, and how to make it provable.
A business letter is a record that happens to contain a request. That is the whole difference between a letter and a message, and it decides everything about how you write one.
A message is addressed to the person you are talking to. A letter is addressed to that person, to whoever they forward it to, and to the file. A year or two later, somebody reads it to find what was agreed.
This page is the general shape: what a letter has to contain, how to decide the first sentence, how to write an ask that can be answered, and how to make the thing provable.
What to take away
- Put the outcome in the first sentence. Readers decide whether to keep reading in one line, and the ones who skim are the ones you most need to reach.
- Every letter needs one ask with a date attached. Two asks means one gets ignored, and no date means nothing happens.
- Write so the letter still works when it is forwarded with no context. That single test catches most defects.
When a letter rather than a message
Not every exchange needs one. The cases where the letter form earns its extra effort are specific.
Letter or short message?
Will you need to prove it later?
Send a formal letter
A short message is better
- When you will need to prove it later.A notice, a claim, a dispute, a change to terms.
- When it will be read by someone you have not met.Anything that goes up a chain, into a file, or to a department rather than a person.
- When it has to stand alone.If the reader would need the previous ten messages to make sense of it, put the necessary parts in the letter.
- When the relationship matters more than the speed.A decline, a complaint response, a price change.
Everywhere else, a short message is better and a formal letter reads as an escalation you did not intend.
The six parts
Almost every business letter contains the same six components. Naming them makes it obvious what is missing. The conventional layouts these parts sit in are set out in the Purdue OWL's notes on basic business letters, which is a useful reference where a house style has to be chosen rather than inherited.
| Part | Its job | The failure when it is missing |
|---|---|---|
| Reference line | Tells the file and the reader what this concerns | The letter arrives with no context and is queued |
| Opening statement | States the outcome or the request immediately | The reader looks for the point and stops looking |
| Facts | The minimum record needed to act, with dates | The recipient has to reconstruct the history |
| The ask | One action, one owner, one date | Everyone assumes someone else will act |
| The route back | Who to reply to, and what to do if the answer is no | The reader has no cheap way to respond |
| Closing and identity | Who is writing, in what capacity, for which entity | The letter cannot be relied on later |
The reference line and the capacity line are the two people drop most often, and they are the two that decide whether the letter is any use as a record.
The first sentence decides the letter
There are only three useful openings, and choosing the wrong one costs you the reader.
Three openings that work
Opening
- State the decision
- News: decline, change, result
- State the request
- Anything you want done
- State the acknowledgment
- Complaint or mistake
- Throat clearing
- Avoid: carries nothing
Use it for
- State the decision
- State the request
- State the acknowledgment
- Throat clearing
State the decision. For anything the reader will experience as news: a decline, a change, a termination, a result. Say it in the first line. Building up to it does not soften it, it just means the reader finds out in a worse mood, having had time to hope.
State the request. For anything you want done. The reader should know what is being asked before they know why.
State the acknowledgment. For a complaint or a mistake. Every sentence of explanation placed before the acknowledgment is read as an excuse, however reasonable it is.
Avoid throat clearing openers such as "I hope this finds you well." They carry nothing and sit where attention is strongest.
The federal plain language guidelines make the same case for public documents. A letter becomes public the moment someone forwards it.
Writing an ask that gets answered
The most common defect in business correspondence is an ask that cannot be complied with.
Five rules for an answerable ask
- One action, or number them and say which is first
- A named person, not a department
- A date, not 'at your earliest convenience'
- Two options where you can
- A stated consequence only if it is real
An ask is answerable when it names one action, one person and one date.
Weak. "Please review the attached and let me know your thoughts at your earliest convenience."
Strong. "Please confirm by 14 March whether you accept the revised delivery date in clause 4.2, or propose a date you can meet."
The weak version names no action, no owner and no date. The strong version can be answered in one line, and it gives the reader a way out if the answer is no.
The five rules behind it:
- One action.
- One named owner, not a department.
- One date the reader can meet.
- A second way to respond if the answer is no.
- The ask inside the first two sentences, not buried at the end.
A general skeleton
Adapt this rather than filling it in mechanically. The bracketed parts are yours.
Letter skeleton, in order
- Your entity name and address
- Recipient name, role, entity, address
- Date
- Rethe matter and reference number
- One sentencedecision, request, acknowledgment
- Facts the reader needs, with dates
- The askone action, person, date
- What happens next, route back, sign off
[Your entity name and address]
[Recipient name, role, entity, address]
[Date]
Re: [The matter, plus any reference number or contract name]
[One sentence: the decision, the request, or the
acknowledgment. No preamble.]
[The facts that the reader needs to act, in order, with
dates. Include the ones that are inconvenient for you; a
letter that omits them stops being useful as a record the
moment the other side supplies them.]
[The ask: one action, one named person, one date. Where
possible, two ways to respond.]
[What happens next from your side, and by when.]
[If relevant: what you will do if there is no reply, but
only if you will actually do it.]
[Route back: name, direct contact, and any reference the
recipient should quote.]
[Sign off]
[Name]
[Role, and the entity you are writing for]
[Enclosures, if any, listed by name]
Two notes on the block above. The capacity line matters: writing as an employee of an entity is different from writing personally, and a letter that does not say which is ambiguous exactly where ambiguity is expensive. And enclosures should be listed by name, because the most common dispute about a letter is whether something was attached to it.
The same skeleton, filled in. Brackets mark what you substitute.
Re: Contract [number], retention withheld at practical completion
We are asking you to release the retention held under contract [number], or to tell us in writing what is outstanding.
Practical completion was certified on [date]. The snag list from that inspection was closed on [date], and your site manager confirmed this in writing.
The ask: confirm by [date, 14 days out] that the retention will be released, or send the list of items you say are outstanding.
If we have no reply by [date], we will refer the matter to [name and role] for a decision.
Reply to me at [email], quoting contract [number].
[Sign off] [Name] [Role, entity]
Making it provable
If you would not be comfortable reading the letter aloud in a room where the facts are disputed, redraft it. Beyond that, the mechanics:
Making the letter provable
- Keep the sent version, not the draft
- Record how it was sent and to what address
- Ask for confirmation of receipt as a separate line
- Do not change a sent letter; send a correction
- Read the agreement first for notice provisions
- Keep the letter as sent, dated. A draft proves nothing.
- List attachments by name in the letter, and keep the files as sent.
- Note how it wentpost, courier, email or portal, with the date.
- Keep the reply, even one that says nothing useful.
- If the letter sets a deadline, do what you said you would do on the day.
State the facts you dislike as plainly as the facts you like.
Before you send
A short pass, in this order, because each step catches what the previous one creates.
Six checks before sending
- Read only the first sentenceoutcome or request?
- Cover everything except the askcould a stranger act?
- Check every date and number against the source
- Remove any sentence telling the reader how to feel
- Check entity names exactly as in the contract
- Ask whether anything needs approval, and get it in writing
- Read the first sentence and the ask on their own. If those two do not carry the letter, nothing later in it will.
- Check every date, amount and reference number against its source.
- Check names, roles, and the capacity you write in.
- Check the ask has one owner, one date, and a reachable date.
- Check the attachments are listed and attached.
- Check that nothing in the letter depends on an earlier phone call.
Then decide the format. Send the letter as a dated PDF for the record, and put the ask in the body of the email too. A reader who cannot see what you want without opening a file may not open it.
For a sensitive letter, such as a dispute, a dismissal or a complaint about a named person, write less than you want to. State the facts, the ask and the date. Keep the tone flat: no apology that admits fault, no sarcasm, no rhetorical questions.
