Klaviyo × Balanced Rock
Klaviyo x Balanced Rock, nonprofit switches from Mailchimp and grows list 35.8% YoY
35.8% YoY growth in email subscriber list
Disjointed and blind to connected and visible
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.
