EMAIL STRATEGY BEYOND REVENUE Tired of sending endless promos? You need a new email strategy. Most email marketing today is stuck in a cycle of discounting to front-load revenue. We help brands move past short-term gains with strategies designed for long-term profitability. With experience working with over 150+ DTC brands—including Carved, Duradry, Waterdrop, Bliss, CoverFX, Wild, and more—we know what it takes to scale sustainably in today’s competitive eCommerce landscape. Why Leading Brands Trust Magnet Monster “We saw too many email agencies stuck in the discount rut. 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. Here’s what sets us apart: • eCommerce Expertise: Our team includes former store owners who know the challenges you face and how to overcome them. • Unit Economics Focus: Every strategy we create aligns with your unique business model to ensure profitability at scale. • Beyond Discounts: We go beyond sending promos by delivering value-led creative content and leveraging email as a growth engine for your business. 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.
