What this page helps you do
Set the voice and style of AI-generated emails so they sound like your brand, not a generic template. You can use presets, add custom instructions, and provide example emails for calibration.Before you start
- A Nudgen account
- A clear idea of how you want to sound (e.g. casual, professional, urgent)
Preset tones
Choose one of four presets to shape the AI’s default style:| Preset | Best for | Example vibe |
|---|---|---|
| Friendly | E-commerce, shops, lifestyle products | Warm, approachable, conversational |
| Professional | B2B, finance, formal contexts | Clear, polished, respectful |
| Playful | Consumer apps, Duolingo-style nudges | Fun, light humor, friendly urgency |
| Urgent | Time-sensitive offers, winbacks | Direct, action-focused, scarcity |
Custom prompt
Add extra instructions so the AI matches your voice more closely. Examples:- “Use short sentences. Avoid jargon.”
- “Reference the user’s name once in the first paragraph.”
- “End with a single clear CTA. No multiple links.”
- “Tone should feel like a helpful colleague, not salesy.”
Example emails
Provide 1–3 example emails that reflect the tone you want. The AI uses them as references when generating new content. Include:- Subject lines you like
- Opening and closing style
- Level of formality
- CTA style
Examples are for tone calibration only. The AI does not copy your text; it learns the style and applies it to new campaigns.
Multiple brand configs
You can save several brand configs (e.g. “Product Launch”, “Re-engagement”, “Support”). When creating a campaign, select which config to use. This lets you switch tone by campaign type without changing a single global setting.What happens next
- Create a campaign and select your brand config. AI will use your tone and prompts.
- Regenerate content if the output doesn’t match — you can tweak the prompt and try again.
