Expand infrastructure
Add IPs, pools, or platform capacity in step with warmup and monitoring.
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
