Objective
Scale sending safely
Increase sending volume on an already warm identity without triggering filters.
Starting state
Current capacity nearing limits or isolation is required
Prerequisites
- Volume forecast
- IP/domain strategy
Estimated time
2–4 hours
Difficulty
advanced
Required access
- ESP/IP provisioning
- DNS
Inputs
- New IPs/pools
- Traffic split plan
Step-by-step instructions
- Provision cleanlyAllocate IPs/pools and align PTR/HELO before any customer traffic.
- Warm new capacityRamp with engaged traffic using a dedicated schedule.
- Shift loadMove production share only after reputation signals look healthy.
Verification
- New IPs show acceptable provider posture
Common mistakes
- Dumping peak traffic onto cold IPs
- Dedicated vs shared for the new workload?
Rollback / recovery
- Pin traffic back to prior pools
Expected outcome
Capacity expands without a reputation shock.
When to escalate
- New IPs listed or blocked during ramp
