How Terra Kaffe drove 2X the revenue of its standard Klaviyo flows with Relvino.

Before: Standard flows, standard returns

Terra Kaffe ran three off-the-shelf Klaviyo flows alongside a behavioral vendor layer. The flows sent the most and earned the least per message — volume without intent — while the added vendor lifted efficiency but not enough to change the ceiling on what abandonment recovery could return.

After: 2X the revenue of standard flows

Relvino's checkout-abandonment series outperformed both incumbents at once: more than 2X the revenue of the brand's three standard Klaviyo flows, on roughly 30% fewer emails, and 60% more revenue than the behavioral vendor in a fraction of its running window. Key highlights:

• 3.5X revenue per email versus the standard Klaviyo flows
• 2.016X ROI
• Highest revenue of any of the brand's three abandonment programs, from the second-lowest send volume
• 99% delivery rate, zero spam complaints, zero unsubscribes across every message sent
• Every email individually personalized by agent, on the first version of the content model

The result came from a first-pass agent configuration, not a tuned one — the efficiency gain is the floor, not the ceiling.
