Short answer / recommendation
Use a Zap with: Trigger (new email) → optional pre-formatter → ChatGPT step that returns strict JSON intent+priority → Zap JSON-parse + routing actions to Zendesk (create ticket / set group/priority / add private AI summary). Keep the model deterministic (temperature 0), force machine-readable output, validate JSON, and send failures to a manual queue.
Step-by-step Zap (practical)
1) Trigger: New Email (Gmail, IMAP, or Zapier Email Parser). Map subject, from, body, headers.
2) (Optional) Formatter / Text Clean: strip signatures, quoted text, long threads. Use simple regex or “Formatter by Zapier” to take the latest message only.
3) Action: ChatGPT (OpenAI) — call for intent detection and priority. Use temperature=0, max_tokens small (200–400). Insert system + user prompt below. Request output as strict JSON.
4) Action: “Parse JSON” (Zapier built-in) or Code by Zapier to validate/clean the response.
5) Filter(s): If confidence < threshold or parse failed, route to “ai-failed” Zendesk queue (manual triage) and add tag ai_failure. Else continue.
6) Action: Zendesk Create Ticket (map subject/body). Set ticket fields: priority (from JSON), group (recommended_queue), tags, public/private comment with AI summary and confidence. If escalate=true, also notify Slack/email to on-call.
7) Error handling: set Zap retry policy, and add fallback step to log to Google Sheet with raw email + AI response for audits.
Reliable prompt (system + user) — require strict JSON
System prompt (concise): You are an assistant that classifies support emails into intent and priority. Always reply only with valid JSON (no extra text). Use this schema: {"intent":"","priority":"urgent|high|normal|low","summary":"1-2 sentence summary","tags":["tag1","tag2"],"recommended_queue":"string","escalate":true|false,"confidence":0.0}
User prompt (include variables): Analyze the email below. Email_subject: "{{Subject}}" Email_from: "{{From}}" Email_body: "{{Body}}" Return JSON according to the schema. Choose intent from: billing, login, bug_report, feature_request, account_closure, general_support. Set priority rules: urgent for security/production-down, high for SLA breach or VIP, normal for typical requests, low for general info. Confidence is a 0.0–1.0 estimate.
Prompt example (single-shot):
"Email_subject: 'Site down' Email_from: 'acct@example.com' Email_body: 'Our production website is down, error 500 on checkout. Please fix.'"
Expected JSON: {"intent":"bug_report","priority":"urgent","summary":"Production checkout returns HTTP 500 preventing purchases.","tags":["production","checkout"],"recommended_queue":"ops","escalate":true,"confidence":0.95}
Error handling and reliability tips
- Force JSON only: model errors mostly come from free-form text. Enforce JSON and use Zapier’s JSON parser to fail fast.
- Validation: if parse fails or confidence < 0.6, mark ai_failed and create Zendesk ticket with tag ai_manual; notify humans.
- Rate limits / retries: use Zapier built-in retry, and exponential backoff. Log raw inputs/responses for audits.
- Determinism: temperature=0, limit tokens, and include a fixed list of intents to avoid hallucination.
- Privacy: strip PII when sending to ChatGPT if needed or use your private API key and keep logs secure.
Decision criteria
- Budget: If cost-sensitive, reduce tokens, or batch low-priority emails to periodic analysis. Large teams can justify higher-cost models for better accuracy.
- Skill level: non-devs can use Formatter + built-in ChatGPT action; dev teams can add Code by Zapier for robust validation.
- Workflow stage/team size: small teams should start with AI-suggest-only (add private note) until confidence is high; larger teams can auto-route.
Deployment checklist
- Map email fields and clean text
- Implement ChatGPT step with strict JSON prompt
- Add JSON parse + confidence filter
- Create Zendesk actions and tags
- Add fallback logging and notify for parse failures
- Run 50–200 test emails and tune prompts
Best-for / Avoid-if
- Best for: faster triage, consistent tagging, high-volume support.
- Avoid if: emails contain lots of PII you can’t send to an API, or you lack capacity for human review during tuning.
