The 4 core tones to master
"Can you review this doc before noon? I need your feedback on section 3."
The professional tone adds a layer of politeness and structure. It builds trust and shows respect. When in doubt, default to this one.
"I'm following up on our conversation from last week. Would you be available for a 20-minute call this week to discuss next steps?"
"Hey! Got 2 mins to look at my deck? Just want to make sure it holds up 😊"
Persuasive writing highlights benefits, anticipates objections and drives action. It must always stay honest and fact-based — manipulation is never a good long-term strategy.
"Teams using Bernadette save an average of 3 hours per week on email rewrites. That's time back for the work that actually matters."
How to choose the right tone
The golden rule: adapt to your reader, not to yourself. Before writing, don't ask "how do I want to express this?" — ask "how does my reader expect to be addressed?"
| Situation | Recommended tone |
|---|---|
| First contact with a prospect | Professional + Persuasive |
| Sales follow-up | Professional + Persuasive |
| Email to a close colleague | Direct or Casual |
| Report or meeting summary | Professional |
| Request to your manager | Professional + Direct |
| Commercial proposal | Professional + Persuasive |
| Internal Slack message | Casual or Direct |
The most common tone mistakes
1. Being too formal with close colleagues
Writing "I hope this message finds you well" to a colleague you have coffee with every morning creates an artificial distance. It can even come across as cold or condescending. Don't be afraid to loosen the register with people you know well.
2. Being too casual with clients
Using "Hey!" or abbreviations in a client email — especially for a first contact — can raise doubts about your professionalism. Trust is also built through the register you use.
3. Shifting tone mid-conversation
If you started an exchange formally, stay in that register unless your contact shifts it first. A sudden change in tone can feel jarring or inconsistent.
Not sure if your tone fits the situation? Paste your text into Bernadette — select "Professional", "Direct" or "Persuasive" and see the difference in one click.
The ideal tone doesn't exist — it adapts
With practice, adapting your tone becomes second nature. Until then, ask yourself two questions before every message:
- Who will read this and what register do they expect from me?
- What outcome do I want — to inform, convince, reassure, or motivate?
These two questions are usually enough to eliminate the most common tone mistakes.
