How to correct a mistake in an email you already sent

Everyone sends a wrong attachment, a broken number, or a misfired reply-all eventually. What people remember isn't the slip — it's whether the correction was fast, clear, and drama-free.

Triage first: does the mistake actually mislead anyone or cause action on wrong information? A typo needs no correction email; a wrong figure in a report needs one immediately; an accidental reply-all needs one short, composed line — not a three-act apology.

Correction etiquette

Correct fast. The gap between your mistake and your correction is the window in which people act on wrong information — minutes matter more than wording.
Put "Correction" in the subject line so it's findable later and skimmable now.
Show old and new side by side. "The deadline is March 12, not March 21 as I wrote" kills ambiguity; "small correction to my last email" preserves it.
Match the audience to the mistake: correct to everyone who got the wrong info, and to no one else. No need to advertise the slip beyond its blast radius.
One apology, then move on. Repeated self-flagellation makes a small mistake feel large and makes others responsible for reassuring you.

Frequently asked questions

Should I use my email client's "recall" feature?

Treat recall as a bonus, never a plan: it typically only works within the same organization, on unread messages, and it notifies recipients that you recalled something — which invites curiosity. Send the correction email regardless.

I accidentally sent confidential information — what now?

This is more than an etiquette problem. Ask for deletion in writing (see template), and if the data involves client information or personal data, notify your manager or data-protection contact promptly — under GDPR, some incidents have reporting deadlines. Fast, honest escalation beats quiet hoping.

Do I need to correct a simple typo?

No — unless the typo changes meaning (a date, a number, a name, a "now" that should be "not"). Correcting cosmetic typos generates more noise than the typo itself.
