How to isolate high-risk segments?

High-risk segment isolation:

Identify high-risk characteristics:

No engagement in 6+ months

Unknown or purchased sources

High historical bounce/complaint rates

Addresses from before current practices

Create exclusion rules:

Segment by last engagement date

Segment by acquisition source

Segment by historical complaint behavior

Prioritize safe segments:

Recent signups with confirmed opt-in

Engaged in last 30-90 days

Known good sources

Phased reintroduction:

Add back moderate-risk segments after improvement

Test high-risk segments carefully, if at all

Inspect cargo for spoilage. Ship only verified good goods during probation.
