Five disciplines, one watchful instrument.
Mailnurse is one product that solves five problems agencies hit at scale. Each discipline can be adopted alone; together they replace the playbook that lives in your head.
Five problems that quietly burn down cold-email programs.
Every page, every blog post, every feature maps to one of these. This is the spine.
Health monitoring
Continuous placement testing, 11-DNSBL probes, warmup vitals every four hours. A composite risk score per account so decay is visible before deliverability collapses.
Learn more 02Auto-rotate domains
When a domain burns, replace it end-to-end: Spaceship → Cloudflare → Workspace → Instantly → warmup. The ten-hour playbook, run while you sleep.
Learn more 03Auto-pause spam
When bounce velocity climbs, DNSBLs hit, or placement drops, the rules engine pauses sends before the campaign goes wider. Eight codified rules with severity tiers.
Learn more 04Auto-replace mailbox
When a mailbox loses engagement or burns its reputation, Mailnurse retires it and assigns a fresh persona — name, photo, identity included — from the pre-warmed pool.
Learn more 05Auto-placement
Warmup schedules locked to the deliverability literature. Send volume auto-adjusts to engagement. Placement re-tested nightly. The score stays high without manual tuning.
