By AI Productivity Hub Editorial Team10 min read
If you can describe a process in plain English, you can build an AI agent. This tutorial walks through an email-triage agent end to end.
Setup
- A Zapier or Make account.
- An OpenAI API key.
- A Gmail account (or Outlook).
- A Slack workspace for approvals (optional).
The 5 steps
- Trigger: new email in inbox.
- Classify: AI tags as 'reply now', 'snooze', 'archive'.
- Draft: AI writes a reply for 'reply now' in your tone.
- Approve: send draft to Slack with approve/reject buttons.
- Send: upon approval, ship the email.
What to build next
- Lead-capture → CRM agent.
- Daily KPI digest.
- Customer support triage.
Key takeaways
- Always include a human approval step early on.
- Tighten scope before you broaden tools.
- Log every step — debugging is otherwise impossible.
