Use meaningful thank-you notesFAQ
Should I send this mentor thank-you note by text or email?
Use the channel that matches the relationship and stakes. Text is fine for personal, immediate conversations. Email is better when you need a record, a calmer tone, or a professional paper trail.
How long should the message be?
Shorter is usually safer. Say the clear thing, include the necessary context, and stop before you start over-explaining. Most hard messages work best in 4 to 8 sentences.
What if they react badly?
Do not argue with the first emotional reaction. Re-state the boundary, apology, decision, or request once. If the situation is sensitive, give them time and follow up later when everyone is calmer.
