The story leads with time saved and manual effort eliminated, which locks in Efficiency as the primary type. The open rate and opt-in lifts are real gains but serve as proof of list quality rather than headline growth claims. The competitive switch from a named legacy platform is explicit, and the small-team framing makes the efficiency wins feel visceral rather than abstract.
