The biggest concern people have about AI email agents is that replies will sound robotic. Generic. Obviously automated. It is a valid concern. Nobody wants their clients receiving a response that feels like it came from a chatbot. The good news is that with the right training setup, your AI agent can reply in a way that is genuinely indistinguishable from you.
This guide walks through exactly how to set up your knowledge base and tone instructions so that your agent replies the way you would.
Step 1: Write Your Service Descriptions Conversationally
Most people make the mistake of writing their knowledge base like a website's "About" page, formal, complete, polished. But your emails probably sound different. Write your service descriptions the way you would actually explain them to a client on a call. Use the same words you use in conversation. Avoid jargon your clients wouldn't use.
- Write short paragraphs, not bullet-point lists
- Include pricing ranges or starting points where you're comfortable
- Mention who the service is best for
- Add any common objections and how you address them
Step 2: Build a Strong FAQ Section
Your FAQ is the most important part of your knowledge base. Think about the last 20 emails you replied to and write down every question that appeared more than once. Those are your priority FAQs. Be specific in both the question and the answer.
A vague FAQ answer like "It depends on the project" gives the AI nothing to work with. A specific answer like "Our brand identity packages start at $1,200 and include a logo, colour palette, and brand guidelines. We can discuss your specific needs on a quick call" is far more useful and gives the agent real content to work from.
Step 3: Set Clear Tone Instructions
Tone instructions tell the agent how to write, not just what to say. Be explicit about the style you want. Examples of useful tone instructions:
- Write in a friendly but professional tone, warm and not casual
- Keep replies under 150 words unless more detail is genuinely needed
- Always address the person by their first name if available
- Do not use exclamation marks more than once per reply
- Never say "As an AI" or reference being automated
- End every reply with a clear next step or question
In Traxvio, you can add all of these as custom instructions in the Agent Settings panel. The more specific you are, the more consistent and on-brand your replies will be.
Step 4: Review the First 10 Replies
Once your agent is live, review the first 10 replies it sends (or drafts, depending on your mode). Look for anything that sounds off, phrasing you would never use, responses that missed the point of the question, or tone that feels too formal or too casual. Each observation is a knowledge base or tone instruction update.
Most users find that after two to three rounds of small adjustments, the agent's replies are indistinguishable from their own. The initial setup is the hardest part. After that, it just runs.
Step 5: Keep It Updated
Your services, pricing, and availability change. Your knowledge base should reflect that. Make a habit of updating it whenever something significant changes, such as a new service, a price adjustment, or a new FAQ you notice repeating in your inbox. An outdated knowledge base is the main reason AI replies start to feel stale or incorrect.
