Thanks! Great questions.

Pulumi updates: Yes, exactly. Pulumi manages infrastructure state and handles diff-based updates. When we ship new features or improvements, users run wraps email upgrade, and Pulumi figures out the minimal changes needed. We also have a versioned metadata system that auto-migrates configs - so if we change how we store deployment info, it upgrades transparently on next run.

Cost tracking: Yes! Every resource we create is tagged with ManagedBy: "wraps-cli" plus service-specific tags (Service: "email", Provider: "vercel", etc.). You can filter by these in AWS Cost Explorer to see exactly what Wraps infrastructure costs.

In practice, the costs are minimal - most users see $0.05-5/mo for the infrastructure itself (DynamoDB, Lambda, SQS). The main cost is just SES usage at $0.10 per 1,000 emails.
