AI Email Responder Agent (Make.com Automation)

If you want customer support that is fast, consistent, professional, and available 24/7, this AI Email Responder Agent is an essential automation system.

This is a complete plug-and-play AI agent that turns every email into a polished response written exactly in the brand voice you choose.

⭐ WHAT THIS AUTOMATION DOES

1. Instantly Detects Incoming Emails via Mailhook The system begins with a Custom Mailhook that captures every new email arriving in your connected inbox. It collects all essential metadata including:

Sender name

Sender address

Subject

Email body

This is the trigger that activates your AI agent automatically — 24/7.

2. Sends Email Data to Perplexity AI for Contextual Understanding The workflow uses Perplexity’s llama-3.1-sonar-large-128k-online model to read the email and generate a policy-accurate reply.

This step includes:

The original email text

The sender’s name

The subject line

A link to the organisation’s policy/FAQ page (the “source of truth”)

The agent is instructed to create a reply that:

Follows a precise email template

Avoids adding anything outside the approved structure

Never injects additional subjects, contacts, or numbers

Only summarizes information based on the linked policy

This ensures perfectly consistent and brand-safe replies.

3. AI Generates a Polished, Human-Like Email Reply Perplexity returns a message formatted exactly like this:

Hi [Name],

Thank you for contacting the Royal Botanic Gardens. We will get back to your question shortly.

In the meantime, our friendly chatbot Roy has summarised the following reply:

"[Policy-based summary goes here]"

Best regards, Royal Botanic Gardens team

This template is pulled directly from your JSON instructions.

Your organisation can adapt this template to any brand, business, or industry.

4. Automatically Sends the AI-Generated Reply Back to the Customer Using the Make.com email module, the workflow sends the AI reply to the original sender.

The system auto-handles:

To: original sender

Subject: predefined (“Thank you for contacting us”)

Body: AI-generated content

Content type: plaintext

This means customers receive an immediate response — even at 3 AM.
