Routes
Each project has routes (at least one default transactional). Sends target a route via routeId, or the default when omitted.
| Kind | Use |
|---|---|
transactional | Product email, receipts, auth |
broadcast | Marketing / bulk-style path |
inbound | Receive path — used when mail arrives via MX |
isDefault is scoped per kind (an inbound default does not unset the transactional default).
You can set isDefault, rename, and delete unused routes (default and routes with send history are protected).
