How to Correct Information in a Professional Email

Put the corrected information near the beginning of the message. The reader should not need to work through an apology before finding the date, amount, or instruction they should now use.

Reference the earlier message and explain whether anything else has changed. If people may already have acted on the error, contact the affected recipients promptly.

Correct a date

Subject: Correction: registration closes 16 October

Hello everyone,

The registration deadline in my earlier message was incorrect. Registration closes on Friday, 16 October, at 5 p.m. London time.

The workshop date and venue are unchanged. I’ve updated the event page and calendar invitation.

Sorry for the error, Alex

A descriptive subject helps readers who may not open every message immediately. “Correction” alone doesn’t tell them which information is affected.

Correct a figure in a report

Subject: Corrected total in the September account report

Hi Morgan,

The total on page 4 of the September report included one account twice. The corrected total is 184 accounts, and the revised report is attached as version 2.

The regional breakdowns were already correct. Please use version 2 for the review, and let me know if you have already shared the earlier copy.

I apologize for the mistake.

Best, Casey

The numbers in this example are fictional. In your own message, confirm the correction against the underlying source before sending another version.

Keep the correction easy to follow

Avoid relying on a color change or a tracked-changes file alone. State the corrected fact in the email and name the replacement document.

If the correction alters a decision or commitment, say so explicitly. A wrong delivery date may affect another team’s schedule, while a spelling correction may need no action.

For an error with a wider impact, explain what you are checking and when you will update the recipients. Don’t claim that all other information is correct unless you have verified it.

Use an apology email when the mistake requires a fuller acknowledgment. If the original information came from an unclear instruction, a clarification request can help prevent another correction.
