This gives Claude the ability to send and receive emails programmatically through dedicated inboxes. You'd use it when building AI agents that need to handle customer support emails, send outreach campaigns, or manage multi-threaded conversations. The draft system is smart for human-in-the-loop workflows where you want Claude to compose emails but need approval before sending. Pods provide proper multi-tenant isolation if you're building a SaaS product where each customer needs their own set of inboxes. The API is clean with good SDK support for both TypeScript and Python, and they've thought through the details like idempotency keys and requiring both text and HTML versions for deliverability.
