Continuous partnership
When the agency first reached out, they were in a familiar spot: big vision, small team, bottlenecked backend. They had just signed their second DTC client, a major milestone, and were already feeling the cracks form in their delivery process.
They weren't worried about getting more clients. They were worried about what would happen if they did. They needed a way to scale, not slowly, not eventually, but right now, without hiring a full internal production team.
The agency had the strategy, the relationships, and a growing pipeline. What they didn't have was a backend that could absorb new clients without breaking. Hiring full time designers, copywriters, and Klaviyo specialists was slow, expensive, and risked overhead they couldn't unwind if a client churned.
What they wanted was a quiet, invisible machine running in the background. One they could trust to handle email execution, deliver in 48 hours, accept unlimited revisions, stay completely white labeled, and scale from 2 clients to 30+ without breaking.
Backend production capped at 2 clients, no clear path to scale
Hiring in-house was slow, expensive, and risked unrecoverable overhead
Existing freelance network couldn't deliver consistent 48 hour turnarounds
Every new client onboarded slowed delivery for existing ones
From week one, we operated like a core internal team they didn't have to manage. Every campaign, every flow, every Klaviyo build flowed through our pod. Written, designed, developed, tested, and delivered.
We built a custom modular design system for each of their brands, allowing us to move fast without compromising on creativity or visual identity. The agency sends us a brief. We return fully built, QA'd, Klaviyo ready campaigns, often in under 48 hours.
When a new client onboards, our pod takes over the entire Klaviyo automation setup. Welcome flows, abandoned cart, browse and checkout abandonment, post purchase, winback, replenishment, custom brand specific automations. We don't plug in templates. We build flows from the ground up based on the brief, product type, and buyer journey. Everything runs through a fully white labeled backend designed to be invisible to their clients. We never email them, never call them, never take credit. It's the agency's name on the work, always.
Daily campaign production, full automation builds, and zero bottlenecks across 30+ brands.
What started as a production fix became a full operating system. Two years in, the agency went from 2 clients to 30+ without hiring internally, and Optimite went from contractor to embedded delivery layer.
Outcome at a glance
They built a world class agency. We built the backend that keeps it running at scale. Two years in, the partnership continues, and the production engine just keeps moving.
