Sender warmup is a slow, compounding process — it builds reputation with mailbox providers over days and weeks of consistent, healthy sending. That timeline is only useful if you can see what's actually happening. The old status display showed internal phase names that required decoding, and in some cases warmup would pause itself when nothing was genuinely wrong. Both problems are fixed.
What changed
The warmup view now tells you what's actually happening — warming, paused, or complete — instead of an internal phase name that meant little without context. We also fixed cases where warmup would pause itself even though sending was healthy, so the status you see now reflects the real state of the mailbox.
How to read it
- Open Connectors and click an email connector, then the Warm Up tab.
- The Warmup Score tracks sender reputation as it builds toward 100 — a higher score means mailbox providers have seen consistent, healthy sending from your address.
- Daily Target and Days Active show the current ramp; the chart below breaks down sent, replied, and spam-rescued mail for the last 7 days, so you can see the pattern behind the score.
Why warmup clarity matters
Phantom pauses don't just lose days — they erode confidence in the data you're using to plan. If warmup appears paused but actually isn't, you might delay a campaign launch unnecessarily. If it's paused for a real reason — an unhealthy sending pattern, an authentication issue — you need to know that so you can act. The two cases require different responses, and the old status string didn't help you tell them apart.
With a status that means what it says and a warmup process that only pauses when there's a genuine reason, you can plan campaign launch timing with more certainty. A warmup score of 80 actually reflects 80's worth of reputation-building — not a process that was sitting still while showing a misleading label.
What happens during a real pause
When warmup does pause for a legitimate reason, the status label reflects that and the tab surfaces the reason. Once the underlying issue resolves — or the automatic cooldown period passes for a temporarily unhealthy mailbox — warmup resumes without manual intervention.
What you should do
Nothing requires action. If a mailbox previously showed an unexpected pause, check the Warm Up tab to see the updated status and whether any action is needed.
