Inbound (inbound.new)

Inbound converts any address into a webhook endpoint with structured JSON, automatic retries, and exponential backoff. Webhook delivery typically under 2 seconds. TypeScript types for the payload.

At an early stage the deciding factors are what the free tier actually covers, what the first paid invoice looks like, and how much of a founding engineer's week the setup costs. Feature depth that only matters at a million sends a month is noise until it is not.

Against a waitlist, a launch announcement, onboarding email, and the first transactional sends, Inbound (inbound.new) covers developer experience, SDK breadth, and webhook coverage, and does not cover scheduling. Whether that gap matters depends on how central those are to the build.
