A segment with six automations attached needed six separate runs, started in the right order, each one waited on before the next made sense — because step four needs the email that step two found.
Run all executes the segment's full chain in configured order, respecting each step's run conditions and each step's dependency on the one before it. Start it once and come back to a fully enriched segment.
Combined with drag-to-reorder automation ordering, this is the difference between an enrichment pipeline you designed and one you have to operate.
