You have dedicated IP enabled and Lumail opened one of:
- Dedicated IP pool is missing — enabled, but no sending pool is configured. Mail may fall back to shared infrastructure.
- Dedicated IP is not ready — warmup status is not
IN_PROGRESS / DONE. Don’t push volume yet.
- Dedicated IP warmup appears stalled — status is
IN_PROGRESS at 0%. No observed volume through the pool.
What to do
- Open Settings → Dedicated IP.
- If the pool is missing, complete setup there or email [email protected] with the org slug. You cannot create the pool in DNS.
- If warmup is not ready, keep volume low until status is done. A cold dedicated IP with a full-list blast will defer and bounce.
- If warmup is stuck at 0%, confirm a real campaign/workflow is actually sending (not only tests to yourself). Tests and mailbox-simulator traffic do not warm the IP.
- Do not switch back and forth between shared and dedicated mid-warmup.
After it recovers
Pool-missing resolves when a pool name is configured. Not-ready resolves when warmup is in progress or complete. Stalled-at-0% resolves when warmup percentage moves or status completes.
