Clusters

A named shared-IP sending environment.

A cluster is a named sending environment. Create always sets ip_assignment to shared. KYC must be approved first. The API returns 403 {error: kyc_required} before that.

Create fields

Field Description
name Required.
size small, medium, or large.
region Stored on the cluster. Default manual.
cluster.json
1 {
2 "cluster": {
3 "name": "edge",
4 "size": "small",
5 "region": "manual"
6 }
7 }

Status and hosts

Field Description
sending_ready Active desired status and a live shared pool.
smtp_endpoint STARTTLS on port 587. AUTH PLAIN.
http_endpoint POST /api/inject/v1 with the SMTP username and password.

Suspend and resume match the cluster page. Suspended clusters fail send with cluster_not_ready.

Dedicated IPs are not customer-provisionable. Create always uses the shared pool.
