# What is List Segmentation?

What is List Segmentation? Dividing the mailing list into subgroups. Raises open rate by 14% and revenue by 760% (DMA).

## How it works in practice

Segmentation turns email marketing from a broadcast into a conversation. An identical newsletter for everyone gets a 2% CR. A specific segment gets 8-12% CR.

- Open Rate — segmentation increases open rate

## Common misconception

'Segmentation is complicated.' Basic segmentation takes 5 minutes in Klaviyo. 4 basic segments already change results.

## How to fix it

No results? (1) data quality — is customer data complete? (2) segment size > 100, (3) relevance — does the message fit the segment?

## Real-world example

A sporting goods store: one newsletter had 1.4% CR. Segmenting into running, fitness, yoga, and swimming raised average CR to 4.8% — 3.4x the revenue.

## Where to start

4 basic segments: VIP, active (90 days), dormant (90-180 days), new (30 days).
