POST
Authentication
Requires x402-verified wallet identity (X-Payment-Proof header). Same
auth surface as /email/quote.
Path Parameters
The bare domain to resume. Must be owned by the caller and currently
pool_status='paused'.Behavior
Restorespool_status to active. Only paused domains can be resumed
— this is a deliberate gate to prevent warmup bypass.
| From | Result |
|---|---|
paused | → active |
warming | 404 — the warmup gate must graduate the domain (daily reconciler), not the caller |
active | 404 — already active |
removed | 404 — not in the pool |
404 domain_not_found whenever the transition isn’t allowed.
Response
The resumed domain.
active.Why is warming → active blocked?
The whole point of warmup is that a freshly-provisioned mailbox
sends low volume into a network of cooperating mailboxes that mark it as
important and rescue it from spam. ESPs (Gmail, Outlook) build domain
reputation from those signals. If the caller could pause a warming
domain and resume it straight to active, that warmup machinery is
defeated and the domain joins rotation with no reputation history —
landing every send in spam.
Warming → active happens only via the daily lifecycle reconciler,
which gates on warmup_score >= WARMUP_ACTIVE_THRESHOLD (default 75).
