The painful status quo

The ten-hour playbook nobody actually runs.

Replacing a burned sending domain takes roughly two hours of Spaceship registration, an hour of Cloudflare DNS, three hours of Workspace tenant setup, two hours of Instantly mailbox provisioning, and two hours of warmup configuration. Each step is fragile. Each step is manual. Each step is the reason agencies tolerate burnout instead of fixing it.

  • Domain registration → DNS configuration → Workspace tenant → Instantly mailboxes → warmup setup is a five-system, thirty-plus-click marathon.

  • Half the burned-domain replacements get deferred indefinitely because the operator doesn't have time today.

  • Manual rotation introduces typos: misspelled DNS records, wrong SPF includes, forgotten DMARC policies. The replacement domain burns within days.

What Mailnurse does

End-to-end provisioning, no human in the loop.

  1. 01

    Detect.

    When monitoring trips a replace threshold (or you fire one manually), Mailnurse marks the burned domain for retirement and selects a replacement candidate from your pre-staged pool.

  2. 02

    Provision.

    Spaceship buys the domain. Cloudflare receives the DNS zone. Workspace creates the tenant. Instantly receives the mailboxes. Warmup begins on a graduated schedule. Every step is logged.

  3. 03

    Hand off.

    When the new domain passes its first vitals threshold, it joins your active fleet. The retired domain is paused, archived, and its automation log is preserved for audit.

Inside the rotation

Five systems, one continuous tape.

Pre-staged domain pool.

Mailnurse keeps a buffer of clean, age-warmed domains ready to deploy. Rotation isn't reactive — the replacement is already half-warmed when burnout is detected.

Automation log.

Every provisioning step is recorded with timestamp, payload, and outcome. When something fails — and at this scale, something occasionally fails — the audit trail tells you exactly where.

DNS verification.

SPF, DKIM, DMARC, MX, and reverse-DNS are all verified post-deploy before the domain is handed to warmup. Typos cannot propagate.

Graduated warmup.

New domains start at three sends per day and climb across two weeks. The schedule is locked to the deliverability literature, not arbitrary intuition.

Auto-rotate FAQ

How rotation works, and what stays in your control.

Do I need accounts at Spaceship, Cloudflare, Workspace, and Instantly?
Yes — Mailnurse runs against your provider accounts using API credentials you authorize during onboarding. You own the domains, the DNS zones, the Workspace tenants, and the Instantly mailboxes. Mailnurse orchestrates them; it does not replace them.
What if a step fails mid-provision?
Each step is idempotent and the automation log tracks where it stopped. The replacement domain stays in a paused state until you (or Mailnurse, on retry) clear the failure. The retired domain stays active until the replacement is verified — so your fleet never has a hole.
Can I trigger a rotation manually?
Yes. From the dashboard, select an account, choose Replace, and Mailnurse starts the pipeline. The same five steps run; you just override the automated detection.
How does the pre-staged pool work?
Mailnurse keeps a configurable number of clean domains per workspace — typically five to ten — purchased on a rolling schedule and partially warmed. When you trigger a rotation, the next pool domain steps in. Mailnurse replenishes the pool in the background.

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.
