Avoid generic "thanks for everything." State: "Thank you for staying late to help me prep for the presentation."

2. Explain the Personal Impact

"Your patience calm down my anxiety and helped me land our biggest client of the quarter."

3. Acknowledge Their Character

"Your generosity proves what a truly exceptional teammate and human being you are."
