03 / ESTABLISH

Warm the route. Watch the real response.

We have managed domain and IP warmups in our own sending operations. For a new approved route, we establish identity, use permissioned engaged audiences, run placement samples and adjust volume to receiver responses—not a calendar alone.

SKY / DELIVERY PRACTICE03 / WARMUP DECISION BOARD

Let the receiver set the pace.

PLAN THE NEXT BATCHPermissioned, engaged recipients

Confirm domain/IP identity, select a relevant segment and cap the next provider-specific increase.

READ THE RESPONSENot just a seed inbox

Review deferrals, complaints, hard bounces and placement samples alongside real audience behavior.

THEN MAKE ONE DECISION PER RECEIVING PROVIDER
EXPANDStable response and healthy audience signals
HOLDDeferrals, uncertain placement or thin evidence
PAUSEComplaint spike, policy concern or hard block
Illustrative stop/go rules; not a universal warmup schedule or inbox guarantee.

For approved new sending routes, migrations or carefully planned volume increases.

02EVIDENCE & INPUTS

Read the evidence
across layers.

01

Domain and IP history

02

Engaged, permissioned recipient segments

03

Deferrals, hard bounces and complaint trends

04

Provider-specific pacing and threshold changes

05

Test-inbox observations, interpreted with caution

03THE WORKFLOW

What happens after
we start looking.

01

Set a baseline

Verify identity and list readiness before the first ramp step.

02

Increase deliberately

Expand by provider and engagement segment rather than forcing volume on a fixed calendar.

03

Pause on evidence

Slow or stop when deferrals, complaints or placement signals change materially.

04A CLEAR WORKING BOUNDARY

We know which part
belongs to whom.

01 / TO START

What we need

Domain/IP history, permitted audience segments, planned volumes, authentication and provider-specific telemetry access.

02 / SKY

What we do

Configure a measured ramp, review receiver and test-inbox signals, and recommend expansion, holding or pausing each route.

03 / YOUR TEAM

What you retain

Permission and list quality, sending-account ownership, and sign-off on schedule and live campaigns.

Engagement model: Establish / warmup project
05WHAT YOU LEAVE WITH

A next step you can act on.

An executable ramp sequence, monitoring checklist and stop/go decisions by receiving provider; not an instant-inboxing promise.
