Ramping up a new outbound calling program

Day one of any new outbound program is the most dangerous. Going from 0 calls to 5,000 calls overnight looks to the carriers exactly like a compromised robocaller. Here's how to ramp up so your program looks like a real business growing normally.

Week 1 — Warm up

• Start at no more than 10% of your eventual target volume per day

• Call your most engaged, most recent customers first

• Watch your answer rate and opt-out rate closely

• Use registered, aged phone numbers — not brand new ones

Week 2 — Expansion

• Gradually increase to 30% of target volume

• Add recipients who are slightly less recent

• Monitor for the first signs of mislabeling (answer rate dropping)

Week 3 — Normalization

• Reach 60-80% of target volume

• If deliverability is stable, you're ready to go full volume

Week 4 — Full operation

• Run at normal volume

• Keep watching opt-out and complaint rates

Signs you need to slow down

• Answer rate drops more than 20% week over week

• Complaint rate above 0.1%

• Opt-out rate above 3% per campaign

• More customers reporting "Spam Likely" labels on your calls

Why this matters

Carrier spam detection works on trends, not snapshots. A gradual ramp tells their systems "this is a real business." A sudden spike tells them the opposite, regardless of whether every call is legitimate.
