Pillar 05 · Auto-placement

Hold inbox placement above 90%.

Mailnurse manages the warmup schedule, adjusts send volume to engagement, and re-tests placement nightly. The score stays high without you tuning the dials.

The painful status quo

Warmup schedules drift, and the operator doesn't notice until placement is gone.

Warmup is the most over-promised and under-managed phase of cold-email infrastructure. Most operators set a schedule, point a warmup tool at it, and check back in two weeks. By then the engagement curve has either failed to climb (warmup ineffective) or climbed too fast (volume increased before reputation supported it) — and the account never reaches healthy placement.

  • Most warmup tools run a fixed schedule regardless of engagement. The schedule keeps climbing even when reputation does not.

  • Operators alert on bounce rate; nobody alerts on warmup slope. Slow warmup goes undetected until the campaign goes live and tanks.

  • Placement re-testing is manual: run Mail-Tester, eyeball the result, hope nothing changed in the last six hours.

What Mailnurse does

Send volume responsive to engagement. Placement re-tested nightly.

  1. 01

    Anchor.

    Mailnurse locks every new mailbox to a graduated warmup schedule — three sends per day climbing across two weeks, calibrated to the deliverability literature.

  2. 02

    Adjust.

    When engagement (open rate, reply rate) tracks below the expected slope, Mailnurse throttles back the send volume until the curve recovers. When engagement runs ahead, Mailnurse promotes the mailbox to the next volume band.

  3. 03

    Re-test.

    Placement is re-tested nightly against the synthetic recipient pool. Drift below 85% inbox triggers a warning; below 70% triggers an auto-pause.

Inside placement management

The warmup that adjusts itself.

Graduated schedule.

Two-week ramp from three sends per day to full production volume. Locked to the curve that consistently produces 85%+ inbox placement at Lanello agency clients.

Engagement-responsive volume.

Send volume scales up only when engagement metrics keep pace with the warmup curve. If engagement lags, volume holds — the schedule waits for reputation to catch up.

Nightly placement re-test.

Every account in the fleet gets a placement re-test against the synthetic pool overnight. Results feed into the composite risk score by morning.

Auto-pause on placement drop.

Crossing the placement floor triggers an auto-pause — no sends until you (or Mailnurse) investigate. The mailbox is preserved; the campaign is not poisoned further.

Auto-placement FAQ

How Mailnurse manages warmup + placement.

Can I use my own warmup tool (Mailreach, Lemwarm, Warmup Inbox) alongside Mailnurse?
Yes. Mailnurse focuses on the monitoring + decision layer; you can keep your existing warmup tool as the actual send engine. Mailnurse reads engagement signals from the connected Workspace + Instantly accounts and adjusts your schedule via your warmup tool's API.
What target placement does Mailnurse aim for?
85% inbox placement is the default floor. Above that, Mailnurse increments volume; below that, Mailnurse holds or throttles. The default is tunable per workspace — some clients prefer a tighter 90% floor; some run looser 80% for high-volume outbound.
How fast does volume climb if engagement is healthy?
The default schedule doubles approximately every three days during warmup. After day fourteen the mailbox moves to "production", which means the schedule is unbounded but still subject to engagement-responsive throttling.
What if placement drops mid-campaign?
Auto-pause fires (per the rules engine), the affected mailbox stops sending, and a notification routes to the workspace owner. From there it goes through the same triage as any other paused account — investigate, fix, resume — or escalates to a replace if the cause is irreversible.

Two disciplines that compound this one.

01

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.

Auto-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.
