How they work

Underground Ecom has 120+ retention marketers and sells a full program: CRM audit and roadmap, retention strategy, creative and execution, automations, and SMS and WhatsApp management. It focuses on fast-growth DTC brands.

Huge Win Media is about a dozen people working only in Klaviyo. Each client keeps the same marketers, writers, and designers every month. Week 1 is a full audit of every flow, campaign, and segment. Week 2 rebuilds the highest-impact flows. Week 3 starts the campaign calendar. After that it runs on weekly syncs, monthly reporting, and a quarterly A/B testing roadmap.

Bottom line: Underground Ecom brings a bigger team and more channels. Huge Win Media brings a smaller, fixed team that only does Klaviyo.
