Draft Gmail Replies With AI

What It Does

This workflow reads your Gmail inbox every four hours, identifies emails that need a reply, and uses an AI agent to draft a professional, context-aware response for each one. Every draft lands directly in your Gmail Drafts folder, ready to review and send with one click. No more staring at a blank compose window.

Why It Matters

The average professional receives 120 emails per day and spends nearly 30 percent of their working day managing them. The hardest part is not reading emails, but starting the reply. The blank compose window, the mental context-switching, and the effort of finding the right tone for each sender takes valuable time. This workflow eliminates the first draft problem entirely. You still read, review, and send every reply, but the AI removes the activation energy of starting. The result is faster response times, fewer missed follow-ups, and an inbox that no longer feels like a backlog.

How It Works

1. Scheduled Trigger: Fires every 4 hours to initiate the workflow.
2. Read Gmail: Fetches unread emails received in the last 4 hours from real human senders, filtering out newsletters, notifications, and automated system emails.
3. AI Agent: Reads each email, extracts the sender name and core request, and writes a professional, context-aware reply under 150 words.
4. Create Gmail Draft: Saves each AI-drafted reply directly to your Gmail Drafts folder with the correct recipient address and subject line pre-filled.

3. Sales professionals who need to respond to inbound leads quickly before they go cold.

Setup

1. Connect your Gmail account, grant all required permissions, and enable ongoing access when prompted.
2. Submit the workflow to the catalog.
3. Watch your Gmail Drafts folder populate automatically every 4 hours with ready-to-send replies.

Customize It

1. Increase the email fetch limit from 10 to 20 if you receive very high volumes during business hours.
2. Add instructions to the AI Agent prompt to match your preferred sign-off name or communication style.
3. Change the 4-hour frequency to every 2 hours during high-demand periods by updating the schedule configuration.

Timezone Note

The trigger fires every 4 hours starting from midnight UTC. If you want the first check to align with your morning, adjust the schedule to start at your local morning hour in UTC.
