Why it works
The case study leads with three growth and engagement numbers going up, making Breakthrough the primary type, though the before-state of disconnected systems and zero tracking visibility gives Clarity a strong secondary presence. The competitive switch from Mailchimp is named explicitly and frames the entire narrative. The 'quantum leap forward' quote does real work by anchoring the emotional before-and-after without the vendor having to editorialize.
Steal this
Pairing a peer-group benchmark comparison (44.8% above median pop-up submit rate) with the customer's own metrics gives the numbers external credibility without requiring a named competitor for that data point.
