Apology Email for a Mistake at Work: 4 Examples

An apology email is most useful when it tells the reader what happened and what they should do now. “Sorry for any inconvenience” leaves both questions unanswered.

Name your mistake without making the recipient work out the impact, and explain the correction you have made or can realistically deliver. If you don’t yet know the full effect, say what you are checking and when you will update them.

You sent the wrong attachment

Subject: Corrected attachment: October workshop agenda

Hi Morgan,

I attached an earlier version of the agenda in my last email. I’m sorry for the confusion. Please use the version attached to this message; the session times on page 2 have changed.

The workshop date and location are unchanged.

Thanks, Alex

Identifying the changed section saves the recipient from comparing two whole documents. Before sending, open the attachment yourself and confirm that it is the correct version.

If you sent confidential information to the wrong person, follow your organization’s incident process promptly. A polite correction email alone may not address that situation.

You gave incorrect information

Subject: Correction to the registration deadline

Hello everyone,

I gave the wrong registration deadline in yesterday’s update. The correct deadline is Friday, 16 October, at 5 p.m. London time, not Wednesday, 14 October.

I’ve corrected the shared calendar and the event page. I apologize for the error.

Best, Nia

Put the corrected information where readers will see it quickly. If someone may already have acted on the error, contact them directly as well as correcting the general announcement.

You missed a commitment

Subject: Revised delivery time for the project summary

Hi Sam,

I didn’t send the project summary by the time we agreed, and I’m sorry. I underestimated the time needed to check the figures.

The figures are now verified, and I can send the completed summary by 11 a.m. tomorrow. If you need something for this afternoon’s meeting, I can send the verified totals now.

Thanks, Lee

The brief reason explains the delay without shifting responsibility. Offer a partial delivery only if it will be accurate and useful. An incomplete document with unclear status can create a second problem.

For a deadline that hasn’t passed yet, use a deadline extension request.

A client received work with an error

Subject: Correction to the brochure proof

Hello Amira,

I noticed that the phone number on the final page of the brochure proof is incorrect. I’m sorry that our review missed it.

We’ve corrected the file and checked the remaining contact details. Please hold the earlier proof and use the replacement attached here. Could you confirm whether the file has already gone to print?

Kind regards, Taylor

Ask about the consequence when it is still unknown. Don’t assure the client there has been no impact before checking, and don’t promise compensation or other remedies outside your authority.

Keep the apology proportionate

A small attachment error doesn’t require several paragraphs of self-criticism. A serious mistake may require more explanation, but repeated apologies still won’t substitute for a correction and a realistic follow-up.

Avoid “I’m sorry you were confused” when your message caused the confusion. Say what you got wrong. Then read the email from the recipient’s perspective: can they tell which information to use and whether they need to take action?
