How to write an apology email to a client for a late delivery
A client who paid in advance and has chased you twice is not reading for politeness. She is reading for three answers: do you admit it, do you know why, and when will the order actually arrive. Here is how to give all three in under 180 words, without grovelling or making excuses.
The task
The briefYou work at a small manufacturing firm. An order Ms Kavita Rao paid for in advance was due last Friday and has not shipped — a supplier failed and nobody told her. She has emailed twice. Write her an email that apologises, explains without making excuses, commits to a new date, and offers something for the trouble.

Planning tip: Apologise in the first line — not the third. Then: what happened, what happens now (with a date), what you are doing about the inconvenience, and one line of next step.
What a strong answer does
The apology is the first sentence, and it names the specific failure (the order that was due on Friday), not a vague ‘any inconvenience caused’.
It owns the silence as well as the delay. Nobody told her, which is a second failure, and admitting it is what starts to rebuild trust.
The cause is one plain sentence followed by what you have changed. The reason explains; it never shifts the blame onto the supplier.
The new date is a real date with a weekday attached, and one you can keep. A cautious date you hit beats an optimistic one you miss.
The remedy is concrete and proportionate (free express shipping, money off this order, a refund if she prefers) and stated as done, not offered as a question.
It ends with one next step and a named person she can reach directly, so she never has to chase a third time.
The tone is sorry, calm and businesslike: human enough to be believed, never so emotional that the facts get lost.
How to structure it
- 1
Subject line
6–10 wordsName the order and say this email answers her: ‘Order #4471: apology and new delivery date’. A client who has chased twice should know from her inbox that this is the reply.
- 2
The apology
20–30 wordsApologise in the opening sentence for the missed delivery and for not telling her. One sentence, active voice, no ‘unfortunately’ and no passive that hides who failed.
- 3
What happened
30–45 wordsOne or two sentences on the cause in plain words, then what you have put in place so it does not repeat: a backup supplier, a daily order check. Leave out internal detail she cannot use.
- 4
What happens now
25–40 wordsThe new dispatch or delivery date with its weekday, and how she will know it has shipped: a tracking number, a call from you. If any part is still uncertain, say which part.
- 5
The remedy
20–35 wordsWhat you are giving her for the trouble, stated as already arranged. If you offer a choice, keep it to two options she can pick with a one-word reply.
- 6
Close and sign-off
15–25 wordsOne line of next step, your direct number or email, and your name and role. Do not apologise a third time here; the facts above are the apology now.
Useful phrases

Opening the apology
- I’m sorry we missed the [date] delivery of order [number], and sorrier still that you had to chase us for news.
- Please accept my apologies, both for the delay and for leaving you without an update.
Explaining without excuses
- The hold-up came from [cause] on our side, and we should have warned you the moment we knew.
- We have since [change you made], so this will not happen to your future orders.
Committing to a date
- Your order leaves our warehouse on [weekday, date] and should reach you by [weekday, date].
- I will email you the tracking number as soon as it is dispatched.
The remedy
- By way of apology, we have [waived the delivery charge / taken X% off this order].
- If you would rather cancel, reply ‘refund’ and I will process it the same day.
Closing
- If anything changes, you will hear it from me first.
- You can reach me directly on [phone] or at this address.
- Kind regards, [Name], [Role]
Common mistakes, and how to fix them
Opening with ‘Hope you are doing well’.
To a client who has chased twice, a pleasantry before the apology reads as avoidance. She has to read past it to find out whether you even accept there is a problem.
Fix: Make the apology the first sentence. Warmth belongs in the close.
‘We apologise for any inconvenience caused.’
‘Any’ suggests you are not sure there was an inconvenience, and the passive ‘caused’ hides who caused it. It is the most recognisable template line in business English, and clients read it as a brush-off.
Fix: Name the failure and own it: ‘I’m sorry we missed Friday’s delivery and didn’t tell you.’
Making the supplier the whole explanation.
The client paid you, not your supplier. ‘Our vendor let us down’ on its own sounds like the problem belongs to someone else.
Fix: Give the cause, then take responsibility for it: say what you should have done and what you have changed.
A vague new date: ‘in the coming days’, ‘soon’, ‘ASAP’.
It guarantees a third chaser, which is exactly what this email exists to prevent, and it signals that you still do not know.
Fix: Commit to a weekday and date you can keep, and say how she will know it has happened.
Formulas from South Asian office English: ‘Kindly bear with us’, ‘We will revert back’, ‘Sorry for the trouble caused to you’.
To most international readers ‘revert’ means ‘go back to an earlier state’, so ‘revert back’ is doubly odd, and ‘kindly bear with us’ asks the person you let down for a favour.
Fix: ‘I’ll update you by Wednesday’ and ‘Thank you for your patience’ say the same thing in plain international English.
Offering the remedy as a question: ‘Would you like some compensation?’
It makes the client negotiate for something you should simply give, and adds another round to the thread.
Fix: State what you have already done, then offer one alternative she can accept in a word.
Apologising in every paragraph.
Four ‘sorry’s and a ‘deeply regret’ sound anxious rather than professional, and they bury the new date she is looking for.
Fix: One clear apology at the top. After that, let the facts and the remedy do the work.
Before you submit: a self-check
Is the apology in the first sentence?
Does the email admit the silence, not only the delay?
Is the cause one or two sentences, with no blame passed on?
Is there a specific weekday and date for delivery?
Is the remedy something already arranged rather than a vague promise?
Could she act on this email without writing back to ask anything?
Questions people ask
How do you apologise to a client for a delay without sounding unprofessional?
Keep it to one clear apology at the start, take responsibility instead of blaming a third party, and spend the rest of the email on facts: the cause, the new date and the remedy. Professional does not mean cold. It means the client finishes the email knowing exactly what happens next.
Should I explain the reason for the delay?
Yes, briefly. A client who is told nothing assumes the worst. One or two plain sentences are enough: what went wrong and what you have done so it does not happen again. Internal detail, such as which supplier or which machine, only belongs in the email if it changes what the client should do.
What can I offer a client to make up for a late delivery?
Something proportionate to the harm and within your authority: free or faster shipping, a discount on this order, a credit on the next one, or a full refund if they would rather cancel. Offer it as done, not as a question, and only promise what you are allowed to give.
How long should an apology email to a client be?
Around 120–180 words. That is long enough to cover the apology, the cause, the new date and the remedy, and short enough to read on a phone in one go. If it runs longer, the extra words are usually extra apologies.
