Subscription Food Box

SeoulBox is a DTC brand that focuses on subscription boxes of unique Korean snacks and k-pop merch. The centrepiece of the company’s marketing efforts was and remains email marketing. That’s where Underground Ecom came in. We utilized strategic retargeting and retention marketing efforts to increase ROI via lowered customer acquisition costs. This method also increased CLTV while meshing well with their subscription business model.


The numbers tell an impressive story of revenue growth from email marketing as a result of working with Underground Ecom. In half a year, we see a nearly 3x increase in email revenue growth. We also find a 2x growth in revenue per email recipient. These wins were generated by using a smart pop-up strategy to drive list growth, as well as utilising rigorous testing and personalization experimentation to improve flagging open and click-through rates. Of course, all of these methods rest upon the solid foundation of an amazing working relationship with our partners at SeoulBox.

Seoulbox started as a shared longing for home. It is now a 7-figure business with a global team and customer base. In 6 months, we have managed to triple Soulbox’s email marketing revenue. Note that $/recipient doubled. Most of the revenue came from campaigns which shows that the existing subscriber list is highly engaged with the brand and is a solid community that will continue to drive repeat business.
