Expert writing Tips
Best practice
While grammatically correct, consider using the more concise and common phrase "rest assured" followed by a clause explaining what one can be assured of. For example, instead of "rest assured about your package", say "rest assured your package will arrive on time".
Common error
Be mindful of redundancy. The phrase "rest assured" already implies certainty. Adding "about" can sometimes make the sentence sound unnecessarily verbose. Evaluate whether it adds value or if a simpler construction would be more effective.
