Why Brand Voice Matters

Small word choices can change how people perceive your brand.

✅ On-brand Examples

  • Start free trial — Clear, direct, and tells you exactly what to do.

  • Get instant access — Focuses on the benefit in simple language.

  • Use SmartBuilder — Uses the correct product name and sounds confident.

❌ Off-brand Examples

  • Embark your journey — Vague and generic. It does not explain the action.

  • Try smartbuilder — Uses incorrect product capitalization and sounds less confident.

  • Unlock powerful capabilities — Relies on buzzwords instead of explaining the benefit.

These small differences build trust, reinforce your brand voice, and help Knak AI Assistant generate content that sounds like your brand every time.

Step 2: Add Writing Prompts That Match Your Brand

Sample Rules

Use these rules as they are, or change them to fit your brand.

1. Use plain, precise language.

  • Do: “You can build and send your campaign in under 10 minutes.”

  • Don’t: “Unlock revolutionary workflow efficiencies in record time.”

2. Avoid banned words like “journey,” “unlock,” “unleash,” and “tailored.”

  • Do: “Use real-time data to improve results.”

  • Don’t: “Unlock tailored insights on your data journey.”

3. Focus on benefits.

  • Do: “Personalized subject lines help improve open rates.”

  • Don’t: “We offer dynamic fields and segmentation tools.”

4. Be confident.

  • Do: “This integration speeds up your workflow.”

  • Don’t: “We believe this integration might improve your process.”

5. Use product names correctly.

  • Do: SmartBuilder, Campaign Analytics, QuickSend

  • Don’t: smartbuilder, campaign analytics, Quicksend

6. Use active voice. In active voice, the subject does the action.

  • Do: “The campaign manager reviews each email.”

  • Don’t: “Each email is reviewed by the campaign manager.”

7. Use the Oxford comma. This is the comma before “and” in a list.

  • Do: “The builder is fast, intuitive, and flexible.”

  • Don’t: “The builder is fast, intuitive and flexible.”

8. Put commas around extra details.

  • Do: “The team, which launched three campaigns, saw results.”

  • Don’t: “The team which launched three campaigns saw results.”

9. Join full sentences correctly.

  • Do: “The test ran successfully, and the results were positive.”

  • Don’t: “The test ran successfully, the results were positive.”

10. Use a colon to introduce a list.

  • Do: “The tool has three features: real-time analytics, email previews, and blocks.”

  • Don’t: “The tool includes: real-time analytics, email previews, and blocks.”

11. Use en dashes for ranges. An en dash (–) is a little longer than a hyphen (-).

  • Do: “Available August 1–15”

  • Don’t: “Available August 1-15”
