Writing in chat: 9 tone-of-voice rules for better conversations

Why chat needs its own writing style

Email is a letter; chat is a conversation. Writing chat as if it were an email — long paragraphs, formal openings, 'Dear Sir or Madam' — feels slow and distant. Chat calls for short sentences, quick acknowledgement and a human tone.

The nine rules

These are the guidelines we use to train our own specialists:

• Open warm and personal: 'Hi Lisa 👋' works better than 'Good afternoon, how may I be of service?'
• Short messages, one idea per message — three short ones beat a single wall of text.
• Acknowledge first, answer second: 'Good question, let me check that for you right away.'
• Pick a consistent form of address that fits your brand — and stick with it.
• Emoji are fine if your brand allows it; one per message is plenty.
• No jargon, no internal abbreviations.
• Say what you can do, not what you can't: 'I'll get that to you today' beats 'That's not possible right away.'
• Summarise and close actively: 'All sorted. Anything else I can help you with?'
• A small typo now and then is more human than robotic perfection — but keep it tidy overall.

Canned responses as an accelerator, not a script

Ready-made answers for your top-20 questions save an enormous amount of time. The trick is to write them in your own tone and always open and close them personally. A canned response that reads like a canned response undermines the conversation.

Conclusion

Tone of voice in chat isn't a marketing luxury — it's a measurable conversion factor. Write the rules down, train your team on them, and review conversations regularly. Consistency of tone is what makes a brand recognisable, even at 9:30pm.
