How to correct a mistake in an email you already sent

When to use it

Use it when you find an error in something you've already shared. Flag it yourself, right away, with the correction. People trust colleagues who catch and fix their own mistakes. Getting found out later does far more damage than the error itself.

Example

In an email or Slack message

Reply to the original email so everyone has the fix in one thread: “Correction: the Q2 total in my last email was wrong. Corrected version attached; the change is on row 12.”
