FAQ

Should I send this complaint email 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.
