How do you correct a typo in an email?

Fix the Mistake

Make a copy of the email. Name the new email “Revised” or “Updated” so you don't confuse it with the original. Change the subject line. Then use the words: Correction, Oops, and We Apologize in the subject line so your recipients know why they received another email.

What are the measures to prevent mistakes and slips?

Use design patterns that communicate how they work to users, encourage users to double-check their work (especially before deleting), and warn before mistakes are made.
