# Email Auto-Response & Deflection

Intercept support emails and attempt resolution before creating a ticket.

## Workflow

### Email Auto-Response Setup

Trigger: New email support channel; quarterly deflection optimization; high email volume period:

1. **Email parsing setup**: Configure SMTP/IMAP integration; set up email parsing rules (extract sender, subject, body, attachments, thread history); filter non-support emails (newsletter opt-outs, BCC forwards, automated replies).
2. **Intent classification**: Train ML model on historical support emails (5,000+ examples); classify into support categories (billing, technical, account, feature request, complaint, spam); set confidence thresholds.
3. **Knowledge base matching**: For each category, define KB article mapping (category → top 5 relevant articles); configure semantic search fallback; set minimum match confidence (0.80).
4. **Auto-response template design**: Create personalized email templates with: greeting, detected issue acknowledgment, relevant article(s), call-to-action ("reply if this doesn't help"), signature; A/B test variations.
5. **Reply-to-ticket workflow**: Configure 24-hour reply monitoring; auto-create ticket if customer replies; preserve full email thread as ticket history; route to appropriate queue.
6. **Spam and abuse protection**: Auto-detect email spam, phishing, harassment; flag for human review; never auto-respond to flagged emails; maintain blocklist.
7. **Launch and monitor**: Enable for low-risk categories first (account questions, general info); monitor deflection rate, false positive rate, customer satisfaction; expand to technical categories after validation.
8. **Continuous optimization**: Weekly review of missed deflections; monthly model retraining with new email data; quarterly template optimization.

### Email Auto-Response Configuration

```
EMAIL AUTO-RESPONSE — CONFIGURATION
======================================

Ingestion:
  Email address: support@company.com (primary)
  Secondary addresses: billing@company.com, technical@company.com
  Parsing engine: Mailparser / Parseur / Custom
  Thread detection: Group emails by conversation thread (In-Reply-To headers)

Classification:
  Model: Custom ML model (trained on 10,000+ historical emails)
  Categories: billing, technical, account, feature_request, complaint, general, spam
  Confidence threshold: 0.85 for auto-response; 0.60–0.85 for human review; <0.60 for ticket creation

Auto-Response Rules:
  Rule 1: If category = "general" AND confidence > 0.90 → auto-respond with KB article
  Rule 2: If category = "account" AND confidence > 0.85 → auto-respond with KB article
  Rule 3: If category = "billing" AND confidence > 0.85 → auto-respond with KB article
  Rule 4: If category = "technical" AND confidence > 0.90 → auto-respond with troubleshooting guide
  Rule 5: If category = "complaint" → NEVER auto-respond; create ticket immediately (Priority: High)
  Rule 6: If category = "spam" → auto-delete (with 30-day quarantine)

Template Structure:
  Subject: Re: [Original subject]
  Body:
    Hi [Sender Name],

    Thanks for reaching out. Based on your email about [detected issue], we think this article might help:

    [Article Title] — [Brief summary]
    [Link]

    If this doesn't solve your issue, simply reply to this email and we'll create a support ticket for you.

    Best regards,
    [Company] Support Team
    [Contact details]
    [Help center link]

Reply Monitoring:
  Window: 24 hours
  Action on reply: Create ticket with full email thread
  Queue: Based on reply content re-classification
  Priority: Standard (unless complaint language detected)
  SLA: 4 hours first response
```

### Email Deflection Analytics

```
EMAIL DEFLECTION PERFORMANCE METRICS
=======================================

Period: Last 30 days

Volume:
  Total incoming emails: 3,500
  Auto-responded: 1,225 (35%)
  Converted to tickets: 1,820 (52%)
  Spam filtered: 455 (13%)

Deflection:
  Resolved without reply: 850 (69% of auto-responded)
  Replied to auto-response: 375 (31% of auto-responded)
  Overall deflection rate: 24% (850 / 3,500)

By Category:
  General inquiries:  85% deflection rate (highest)
  Account questions:  65% deflection rate
  Billing questions:  45% deflection rate
  Technical issues:   30% deflection rate (lowest — complex issues)
  Complaints:         0% deflection rate (by design)

Quality:
  False positive rate: 3.2% (auto-responded to email that needed human)
  Customer satisfaction (auto-response): 3.8/5.0
  Customer satisfaction (ticket): 4.4/5.0
  Complaint rate: 0.8% (emails where customer complained about auto-response)

Optimization Opportunities:
  1. Add more specific billing articles (currently 45% deflection vs. target 60%)
  2. Improve technical troubleshooting guide (30% → target 45%)
  3. Add video response option for visual troubleshooting
  4. Personalize article selection based on customer plan tier

## Edge Cases

- **Threaded conversations** (customer replies to auto-response with additional questions):
  - Detection: Parse In-Reply-To headers; match to original auto-response
  - Behavior: Create ticket with full thread history; flag as "previously auto-responded"; agent sees entire context
  - Risk: If customer asks something the auto-response already covered, agent should reference original response
  - Quality check: If customer says "I already read that, it didn't help," escalate priority

- **Bulk email complaints** (customer sends complaint about receiving auto-response):
  - Detection: Complaint keywords ("why did I get an automated reply?", "I need a human", "stop auto-reply")
  - Behavior: Immediate ticket creation (Priority: High); route to team lead; suppress future auto-responses for this customer for 30 days
  - Prevention: Always include clear "reply to get human" CTA; monitor complaint rate weekly; if >2%, investigate template quality

- **Time-sensitive emails** (customer mentions urgent deadline, system down, payment processing issue):
  - Detection: Urgency keywords ("urgent", "ASAP", "down", "broken", "deadline", "lost money")
  - Behavior: Skip auto-response; create ticket immediately (Priority: High); send acknowledgment email within 5 minutes
  - SLA override: 1-hour first response for urgent-detection tickets
  - Risk: False urgency detection → unnecessary high-priority tickets; balance sensitivity carefully

- **Non-English emails** (customer writes in different language):
  - Detection: Language detection on email content (Google Cloud NL, Azure Translator)
  - Behavior: If top 5 supported languages → translate, classify, auto-respond in original language with translated article
  - Quality: Non-English auto-response quality lower; set higher confidence threshold (0.95 vs. 0.85)
  - Fallback: Other languages → create ticket; route to bilingual agent or flag for translation

- **Automated email detection** (avoid auto-responding to auto-responders, newsletters, system notifications):
  - Detection: Check Auto-Submitted header; From address pattern; content analysis for automated patterns
  - Behavior: Skip auto-response; do not create ticket; log for analytics
  - Common sources: Receipt confirmations, delivery notifications, calendar invites, newsletter confirmations
  - Challenge: Distinguish "automated receipt with question attached" (should create ticket) from pure automated email
