The story leads with three upward metrics anchored by a 63% revenue number, which makes Breakthrough the clear primary type over Efficiency. The competitive switch from Mailchimp is named explicitly, giving the piece a before/after contrast that sharpens the payoff. The tactical detail on nurture and win-back flows gives readers something concrete to borrow, not just a results slide.
Pair each metric with an 18-month time window in the headline stats block so readers can judge velocity, not just magnitude.
