Flowium is a full-service Email & Lifecycle Marketing Agency and Klaviyo Elite Partner. We help ecommerce brands grow through performance-driven retention marketing.

Email sits at the center of everything we do as it delivers the strongest ROI of any retention channel. It’s the fastest, most cost-efficient way to increase repeat purchases and customer lifetime value.

Based on your needs, we also activate additional lifecycle channels—SMS, WhatsApp, RCS, Instagram DM automation, push notifications, and direct mail—to reach customers across all key touchpoints and boost conversion.

Together, these channels create a stronger retention system that turns more customers into repeat buyers.

Our core email service includes:

• Klaviyo account setup and optimization
• Full email strategy (abandoned cart, browse recovery, welcome series, and more)
• Campaign content calendar and planning
• On-brand copywriting that connects with your customers
• Mobile- and dark-mode-optimized email design
• Technical setup and ongoing maintenance
• Continuous testing and optimization

Every Flowium team member is an expert in their field, whether that’s copywriting, design, brand strategy, or the Klaviyo software, working together to bring you top-tier results.
