Match your tone to industry norms and relationship formality levels. A startup mentor might appreciate casual language, while corporate mentors typically prefer formal communication structures.

Timing matters significantly in mentor appreciation. Send milestone messages within 48 hours of achievements, while ongoing gratitude works best on monthly or quarterly schedules that respect their time constraints.
