Email Automation

AI-Powered Email Triage

The Email Problem

The average professional receives 120 emails per day. Most are routine — newsletters, notifications, FYIs. A few are urgent and need immediate action. The rest fall somewhere in between. Manually triaging this volume wastes 30-60 minutes daily.

AI email automation doesn't replace email. It makes email manageable by handling the sorting, summarizing, and routing that humans do poorly at scale.

Classification: The First Layer

Email classification assigns every incoming email to a category. A practical classification scheme:

Category	Criteria	Action
Urgent	Customer escalation, system alert, deadline today	Immediate Slack alert + draft response
Action Required	Request, question, approval needed	Daily digest with summaries
FYI	Status update, newsletter, announcement	Weekly digest or auto-archive
Spam/Noise	Marketing, cold outreach, automated notifications	Auto-archive, no notification

The AI reads the full email — subject, body, sender, thread context — and assigns a category with a confidence score. Emails with confidence below 70% get flagged for human review instead of auto-routed.

Summarization: Reading Emails For You

Long email threads are the worst productivity killer. A 15-message thread about a project update contains maybe 3 important points buried in pleasantries and quoted replies.

AI summarization extracts:

Key decisions made in the thread

Action items with who's responsible

Open questions that need answers

Deadlines mentioned anywhere in the thread

A 15-message thread becomes a 4-line summary. You read the summary, decide if you need the full thread, and move on.

Draft Responses

For routine emails — meeting confirmations, information requests, status updates — AI can draft responses that you review and send. The workflow:

AI reads the incoming email

Identifies the type of response needed

Drafts a response using your writing style and context

Presents the draft for your approval

You edit if needed, then send

The goal isn't to automate sending (that's risky). It's to automate the thinking and writing, leaving you with a quick review step.

Priority Routing

Different emails should go to different places:

Customer complaints → #support channel + ticket system

Sales inquiries → #sales channel + CRM

Internal requests → Relevant team member's DM

Invoices → #finance channel + accounting system

Routing rules combine classification with sender context. An email from your biggest customer gets higher priority than the same content from an unknown sender.

Building Your Email Workflow

In this module, you'll build a complete email triage system using the 200 pre-seeded emails in your project. The workflow:

TRIGGER: New email in inbox
  → Classify (urgent / action-required / fyi / spam)
  → Summarize (3-line summary with action items)
  → Route based on classification
  → If urgent: Slack alert with summary
  → If action-required: Add to daily digest
  → If fyi: Auto-archive with tag

By the end, your inbox is sorted, summarized, and routed — automatically.

Measuring Success

Track these metrics to know your email automation is working:

Time to first response on urgent emails (should decrease)

Emails manually triaged per day (should decrease by 80%+)

Misclassification rate (should be below 5%)

False urgents (non-urgent emails marked urgent — annoying but safe)

Missed urgents (urgent emails not flagged — dangerous, track carefully)
