Professional
Calm & neutral
Clear, measured, and appropriate for workplace communication.
Blunt
May be misread
Direct but potentially perceived as curt or dismissive — worth a second look.
Frustrated
Emotionally risky
Emotion is showing. This may escalate tension or put the reader on the defensive.
Aggressive
High risk of offense
Accusatory, inflammatory, or hostile language detected. High chance of negative reaction.
Confident
Assertive & persuasive
Strong, self-assured voice that commands attention without being aggressive.
Unclear
