Can segmentation approaches be A/B tested?

Yes, segmentation strategies can be A/B tested to validate that targeting actually improves results:

Test targeted vs untargeted: Send segment-specific content to one group and generic content to the same segment. Does targeting actually help?

Test segmentation criteria: Compare segments defined by behavior versus demographics versus purchase history. Which segmentation approach produces better results?

Test segment-specific content: Does the content you created for a segment actually resonate better than alternatives?

Measurement approach:

Compare engagement metrics between targeted and control groups. Calculate the lift from segmentation. Assess whether the lift justifies the complexity and cost.

Segmentation is a hypothesis that specific groups respond differently. Testing validates whether your segments are actually meaningful.
