So, we built a framework that not only drives revenue but also supports your entire business.” As Klaviyo Elite Master Partners, we’ve worked with some of the world’s most ambitious eCommerce brands. But we’re not just an agency. We’re your strategic partners in growth.

Email That Works Harder Than Sales Your customers deserve more than endless campaigns pushing discount codes. We help you leverage email to: • Collect qualitative data for deeper customer insights. • Capture more UGC to enhance your omnichannel experience. • Nurture customers with content that adds value, not just discounts. • Build a zero-party data strategy to supercharge acquisition and retargeting. • Proactively support customers with thoughtful touchpoints that strengthen loyalty. Yes, we’ll increase your sales and profitability. But our true value lies in helping you build a resilient business, one that thrives without relying on unsustainable tactics. Boutique and Proud Scaling an eCommerce business is harder than ever. Rising CAC and natural churn make retention more critical than ever but also more complex. At Magnet Monster, we stay small by design. We don’t want to be the biggest agency. We want to be the best. If you’re ready to break free from the discount cycle and create a strategy that drives long-term profitability, we’d love to help.
