Automating Emails with ChatGPT and Gmail: A Practical Guide

If you’ve ever stared at your Gmail inbox thinking, “If one more person asks me to circle back, I’m circling out of this job”—you need AI on your side. With a little help from ChatGPT and Gmail, you can stop drowning in emails and start automating the boring stuff. Here’s how.

Why ChatGPT + Gmail?

Gmail already has some solid filtering and smart reply features, but when you plug in ChatGPT (via tools like Zapier or Make), it becomes a full-fledged assistant. Think:

• Writing draft replies.

• Sorting and tagging emails.

• Summarizing long threads (because nobody has time for a 47-message back-and-forth).

1. Automatic Email Drafts

• Use case: You get similar emails all the time—client inquiries, meeting requests, support questions. Why rewrite the same thing?

• Setup:

  1. Use Zapier’s Gmail → OpenAI integration.

  2. Every time a new email arrives with certain keywords, ChatGPT drafts a reply.

  3. Gmail saves the draft for you to approve (no rogue robots sending “Dear Sir/Madam” on your behalf).

• Tools: Zapier Gmail + OpenAI.

Time saved: ~20 minutes a day.

2. Summarizing Long Email Threads

• Use case: Long email chains are the productivity equivalent of quicksand.

• Setup:

  1. Create a Zap: Gmail → OpenAI.

  2. When an email thread exceeds, say, 5 messages, ChatGPT generates a short summary.

  3. The summary is sent back to you via Gmail or Slack.

• Tools: Make Gmail + ChatGPT Scenario.

Time saved: Your sanity. Also, ~10 minutes per long thread.

3. Tagging & Prioritizing Emails

• Use case: Not all emails deserve equal attention (looking at you, newsletters).

• Setup:

  1. When new emails arrive, send the text to ChatGPT.

  2. Ask it to classify: urgent, client, admin, promo, or ignore.

  3. Apply Gmail labels automatically.

• Tools: Zapier Gmail + OpenAI custom prompt.

Time saved: ~15 minutes/day + better focus.

4. Generating Quick Replies

• Use case: Sometimes you don’t need Shakespeare, you just need a polite, professional “Yes, that works” or “Got it, thanks.”

• Setup:

  1. Create a Zap: Gmail → OpenAI.

  2. Ask ChatGPT: “Generate a short, polite reply to this email.”

  3. Drop it back as a draft in Gmail.

• Tools: Zapier Gmail + OpenAI.

Bonus: Add tone instructions like casual, formal, or enthusiastic so you don’t accidentally sound like a robot or a lawyer when you mean “friendly.”

5. Weekly Email Digest

• Use case: Instead of checking Gmail 87 times a day, get a neat weekly (or daily) summary.

• Setup:

  1. Zapier collects all emails from the week.

  2. ChatGPT condenses them into a digest.

  3. Gmail/Slack delivers it to you.

• Tools: Zapier Gmail + OpenAI + Google Docs/Slack integration.

Time saved: ~1 hour/week.

The beauty of automating Gmail with ChatGPT is that it doesn’t replace you—it just gets rid of the repetitive, brain-draining parts of email. You still have full control over what gets sent, but you’ll spend way less time typing “per my last email” and way more time on work that matters. Or, let’s be honest… scrolling memes guilt-free.
