Switching as teams choosing a transactional API

Judged purely as an API. What the request contract guarantees on retry, how complete the webhook event coverage is, whether suppressions are readable and writable programmatically, and how much the message log retains when something needs debugging in production.

maddy does not cover idempotency keys, webhook coverage, event stream, the suppressions API, batch sending, and SDK breadth. Novu, Plunk, and Postal close that gap. The order below weighs this audience's priorities first, so it differs from a general popularity ranking.
