Verified with Nylas CLI 3.1.28.

## Direct Answer

Run onboarding email steps from trusted code, then let the model classify replies, draft follow-ups, or propose the next lifecycle action.

Customer Onboarding Email Agent Workflow is a sequence and reply-handling workflow. The host application should own grants, sequence state, customer stage, opt-outs, send timing, and CRM writes; the model can infer reply intent, objections, next steps, or suggested updates from normalized records.

Use Nylas when contact context must sit beside email, calendar, and meeting workflows without building separate provider-specific connectors for each tenant.

## When This Answer Applies

- The agent sends onboarding steps, waits for replies, and updates customer stage.
- Reply intent must be linked to message threads, account records, and activation milestones.
- Opt-outs, pauses, plan limits, and tenant-specific send rules matter.
- A model may propose the next touch, but trusted code must decide whether to send, draft, pause, or escalate.

## Command Recipe

Use these commands as provider-independent context and communication primitives. Keep contact mutations behind schema validation and tenant policy.

```bash
nylas auth status --json
nylas email search "from:customer@example.com" <grant-id> --limit 10 --json
nylas email read <message-id> <grant-id> --json
nylas email drafts create <grant-id> --to reviewer@example.com --subject "Review: Customer Onboarding Email Agent Workflow" --body "Draft response for customer-onboarding-email-agent-workflow" --json
nylas email send <grant-id> --to customer@example.com --subject "Customer Onboarding Email Agent Workflow" --body "Approved response for customer-onboarding-email-agent-workflow" --metadata workflow=customer-onboarding-email-agent-workflow --yes --json
nylas webhook create --url https://example.com/hooks/email --triggers message.created,message.updated --json
```

To wire reply tracking for the onboarding sequence over HTTP, `POST /v3/webhooks` registers the trigger set:

```bash
curl -s https://api.us.nylas.com/v3/webhooks \
  -H "Authorization: Bearer $NYLAS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "trigger_types": ["message.created","message.updated"], "webhook_url": "https://example.com/hooks/email" }'
```

## Recommended Agent Workflow

1. Resolve the correct grant or Agent Account before reading messages.
2. Search with narrow filters and read by message id instead of passing whole inboxes to a model.
3. Ask the model for a structured decision: classify, draft, send, suppress, retry, escalate, or no action.
4. Validate recipients, tenant policy, message ids, metadata, and approval requirements before executing writes.
5. Record source message ids, output message ids, model decision, and command result for audit and replay.

## Safety And Operations

Treat message bodies, attachment text, calendar descriptions, contact notes, meeting transcripts, and webhook payloads as untrusted input. Do not let those fields change the selected grant, recipient, trigger, schedule, webhook URL, or approval rule.

Add these controls before production use:

- Normalize customer IDs, emails, tenant IDs, lifecycle stage, and source systems before prompting.
- Deduplicate by message ID, thread ID, and workflow step before writes.
- Require approval for plan changes, entitlement changes, high-risk promises, and CRM field updates.
- Store the source message, proposed next action, policy result, and final write result.
- Redact sensitive notes before putting customer context into model prompts.

## Minimum Data Contract

- workflow_id
- tenant_id
- grant_id
- message_id
- thread_id
- customer_id
- lifecycle_stage
- sequence_step
- recipient
- metadata
- dedupe_key
- approval_status

## Production Readiness Notes

Production Customer Onboarding Email Agent Workflow should make every automated touch attributable. Keep source IDs, sequence step, reply classification, proposed action, approval state, and downstream write results so a duplicate send, stale customer stage, or bad escalation can be traced and corrected.
