Email triage: classify & draft replies

Level: BeginnerSteps: 6Updated July 2026

In short

Your inbox almost sorts itself: ChatGPT classifies emails as urgent, normal or spam, summarises them in one sentence and drafts a polite reply. In the premium variant, Make.com or Zapier does this automatically for every new Gmail – including a label and a ready-made draft reply in your mailbox.

Free

  1. Set up filters and labels in Gmail for rough sorting.
  2. Paste longer emails into ChatGPT.
  3. Have it classify plus draft a reply, check and send.
Example prompt

Here is an email: [TEXT]. Classify it (Urgent / Normal / Can wait / Spam), summarise it in one sentence and write a polite, concise reply draft in my name.

Limits: Manual per email, no automatic labelling.

Premium / Automated

  1. Set up the trigger “new email in Gmail”.
  2. AI classifies and assigns a label automatically.
  3. The reply draft is saved directly as a Gmail draft.
Example prompt

Here is an email: [TEXT]. Classify it (Urgent / Normal / Can wait / Spam), summarise it in one sentence and write a polite, concise reply draft in my name. Respond with JSON: category, summary, draft.

Added value: Automatic sorting plus ready drafts without manual triggering.

Frequently asked questions

Is it safe to paste emails into ChatGPT?

Only paste what you would show an external service provider, and remove sensitive data like passwords or account numbers. For permanently sensitive mailboxes, the automated variant with clear rules or an AI mail client is the cleaner solution.

Does the automation send replies without my okay?

No – in the recommended setup, replies are only saved as drafts in your mailbox. You skim them and send them yourself. Fully automatic sending is possible but not advisable for most people.

Does this also work with Outlook instead of Gmail?

Yes. Make.com and Zapier have Outlook blocks with the same triggers (new email) and actions (label, draft). The workflow stays identical – only the mail block is swapped.
