Speed to lead wins deals, but you cannot watch the inbox 24/7. An AI auto-reply answers instantly and only escalates when it should. Here is how to build it in n8n, and the one-click way in PhewDo.
What you are building
Here is the shape of the workflow.
Inbound messageTrigger
A new message arrives on email, WhatsApp or chat.
Draft a replyOpenAI
The LLM drafts an answer from your knowledge base.
Confidence gateIF
Auto-send if confident, otherwise route to a human.
Send and logAction
Send the reply and log the thread for follow-up.
How to build it in n8n
The trick is a confidence gate so AI never sends a bad answer. Four nodes.
- Trigger node. Catch inbound messages from your channels.
- OpenAI node. Draft a reply grounded in your FAQ or knowledge base.
- IF node. Check the model confidence or a keyword rule.
- Send node. Auto-send confident replies, route the rest to a human.
- Log node. Record every thread so follow-up never slips.
Keeping the knowledge base fresh, tuning the confidence gate and stopping hallucinations are ongoing work in n8n.
