Postmark
This is a router skill that delegates Postmark API tasks to five specialized sub-skills: sending emails (single, batch, or templated), processing inbound email via webhooks, managing Handlebars templates, configuring delivery and bounce webhooks, and following email best practices for deliverability and compliance. It's well organized with clear routing logic, so you can ask "send a batch of emails" or "set up DKIM" and get sent to the right place. The sub-skill breakdown makes sense for a mature email platform with distinct concerns like inbound processing versus sending. Good choice if you're building transactional email into an app and want the AI to handle authentication, SDK installation, and the difference between transactional and broadcast streams without you explaining Postmark's architecture every time.
