Why it works

The story leads with resource constraints and time saved, making Efficiency the clear primary type. The secondary Breakthrough tag is warranted because the piece also highlights strong open rates and the milestone of 1 million adoptions, numbers going up alongside the efficiency gains. The quote from the COO is specific and functional, grounding the automation claim in a real workflow rather than vague praise.
