Responding to every email manually can be a massive time sink, especially if you receive dozens — or even hundreds — daily. Thankfully, with AI-powered automation, you can handle repetitive emails instantly, while still keeping them personalized and professional.
In this guide, I’ll walk you through how to automate email responses with free tools, plus give you examples you can implement right away.
1. Why Automate Email Responses?
Before we dive into the tools, let’s address the “why.”
Automation saves you hours each week, eliminates delays, and ensures consistency in tone and messaging.

2. Choose Your AI Tool
While there are many premium AI email assistants, you can start for free with:

3. Set Up Gmail Filters
First, identify emails you want automated. In Gmail:
- Click the search bar dropdown.
- Enter keywords (e.g., “Invoice,” “Application Received”).
- Click Create filter → select Forward it or Apply label.
This filtering ensures your automation tool only processes relevant emails.
4. Connect Gmail to Zapier
Using the free Zapier plan:
- Trigger: New email with specific label.
- Action: Send the email content to ChatGPT for drafting a reply.
- Action: Send drafted reply back to Gmail for review or auto-send.
