Definition
A warm IP has built a track record of consistent, well-received sending, earning trusted reputation with filters.
Warmth is not permanent; it requires sustained good sending practices.
Warmth is the state every sender wants, but it must be maintained through consistent, engaged sending. Complaint spikes and long silences cool an IP, often without warning. Monitoring placement lets you correct course early.
