The trick is specificity. Thank them for a particular thing — flexibility during a hard month, a reference, honest feedback — and it reads as gratitude, not flattery.
How to write it
- Name the specific thing you’re thankful for.
- Say what difference it made.
- Keep it short — two or three sentences.
