Splitting a list into groups so each gets messages that suit it.

In practice

Common splits are by interest, location, purchase history, engagement or customer stage. Keep segments large enough to measure and label them clearly.

Verification and sending

Segment by verification result too: valid addresses get the main send, catch-all and role get a deliberate smaller one.
