Email is where tone problems cost the most: the reader can't hear your voice, there's no context to soften a misfire, and the message sits in their inbox as evidence. ToneAI's email tone checker reads your draft and shows whether it sounds too formal, too casual, too cold, too aggressive, too vague — or appropriately professional, friendly, and polite.
"Please be advised that…" reads as distant in a workplace that messages in plain sentences. Formality is a dial; most internal email should sit well below maximum.
Slang and shorthand that lands fine in a chat window can read as careless in an email to a client, a hiring manager, or someone senior.
All business, no warmth. It gets the job done and quietly damages the relationship — especially in support and customer communication.
Short sentences, imperatives, and deadlines with no softening read as demands even when you didn't mean them that way.
When the ask is buried under politeness, the reader may not understand what you need or by when — and you both pay for the follow-up.
The target: a message that respects the reader's time, sounds like a competent human, and makes the ask unambiguous. The checker tells you how close your draft is.
Paste the body of the email — greeting and sign-off included, since they carry a lot of tone. ToneAI analyzes how the message comes across and highlights the characteristics it detects. If the read-out doesn't match your intent, rewrite the email toward the tone you want in the same flow, then send the version you're comfortable signing.
You can. Subject lines carry tone too, and ToneAI will read whatever text you paste. Including it is often useful — a formal body under a casual subject reads as inconsistent.
It identifies tone characteristics like directness and warmth. Phrasings that commonly read as passive-aggressive — 'per my last email', 'as previously mentioned' — tend to register as cold or aggressive, which is a useful signal to soften them.
Yes. One-line replies are where tone problems hide, precisely because there's so little context to soften them.
Trust your judgment. The analysis is informed feedback based on how similar phrasing typically reads; you know the relationship and context better than the tool does.
Every ToneAI page runs on the same rewriting engine, so whichever route you start from, the tool behaves the same way and your text is never used to train models.
