KapturBox

KapturBox is a boutique retention marketing agency specializing in email and SMS marketing for direct-to-consumer (DTC) and eCommerce brands. Founded by Joel and Sam, the company focuses on turning email and SMS channels into reliable revenue-generating systems that help brands increase customer retention, repeat purchases, and lifetime value.

The agency provides a comprehensive range of email and SMS retention services, including campaign strategy and creation, email and SMS calendar planning, copywriting, design, quality assurance, flow development and optimization, pop-up and list-growth strategy, customer-retention optimization, and retention reporting. KapturBox also provides platform migration services, including migration to Postscript.

KapturBox has particular expertise with Klaviyo and positions itself as a Klaviyo-focused retention partner. Its work includes building and optimizing automated email flows, developing promotional campaigns, improving customer journeys, and using segmentation and personalization to increase engagement and revenue.

The company works primarily with eCommerce and DTC brands, helping them maximize revenue from existing customers rather than relying solely on acquiring new customers. Its website highlights strong performance metrics, including an average of 49.7% of revenue attributed to Klaviyo among its clients and a 97% average increase in onboarding email revenue in 2023.

KapturBox operates with a hands-on team that includes retention leads, Klaviyo specialists, analysts, designers, and business-development professionals. The founders emphasize becoming an extension of the client's team and taking ownership of retention activities, from strategy and creative execution through optimization and reporting.

With its focused expertise in email marketing, SMS marketing, Klaviyo, retention strategy, automation, customer lifecycle marketing, list growth, and eCommerce retention, KapturBox helps DTC brands turn existing customer relationships into sustainable revenue and build stronger long-term customer value.
