Apology to a Client for Wrong Information: Correct the Record

Separate the old statement from the correct fact

Quote only enough of the earlier information to identify it, then give the verified replacement. If a file is involved, label the current version clearly. Avoid leaving several links with unclear status. The recipient should know which reference to use without comparing every message in the thread.

Explain the known consequence

If the wrong figure or date affected planning, acknowledge that. Do not assume no action was taken just because the client has not complained. Ask a focused question if you need to understand the effect. Keep the message about correction rather than persuading them that the error was harmless.

Reach the relevant audience

Send the correction to people who received the inaccurate information and need the update, using the appropriate business route. Avoid widening distribution to unrelated contacts. If private material is involved, keep the handling within the organization’s normal process instead of reproducing it in an apology page.

Change the verification step

Identify a practical check before the next confirmation, such as using the agreed source record or checking the final version. Do not claim a new procedure is in place unless it is. A specific completed check is more useful than a broad statement that quality has become the top priority.
