In practice
It is simple and usually blunt: everyone gets the same thing whether or not it suits them. Segmenting by interest or activity, even in two groups, tends to reduce complaints and unsubscribes.
Verification and sending
A blast is where a stale list hurts most, because every dead address is hit at once. Verify first.
