Hydrinity has partnered with OAKS since spring of 2024, and our focus has been to support revenue growth by creating on-brand, targeted campaigns that reflect the brand’s premium positioning.

The challenges

→ The list was growing at a rapid pace, and they needed to ensure open and click rates continued to stand strong

→ Email marketing had to continue driving a significant amount of D2C revenue – it was our job to boost the revenue per recipient and placed order rates in the account

→ The email designs needed to be elevated to match the evolving brand standards

The solutions

→ Consistent Campaign Cadence‍

We established a sending rhythm of 8–12 emails per month to drive education, visibility, and timely product promotion.

→ High-Impact Creative

Every campaign blends elevated design, compelling copy, and branded photography—including both model and product imagery—to improve engagement and conversion.

→ Lifecycle Innovation

We built a quiz-based welcome flow that helps new customers discover their ideal skincare routine—delivering a personalized touchpoint that supports trust, education, and higher AOV.

The results

→ Campaign conversion values have increased more than 194% year over year.

→ Email campaigns bring in an average of $0.4 in revenue per recipient, where the industry median is $0.08.

→ Email marketing accounts for 32% of attributed revenue for the brand.

→ Email flow average order value has increased 25%, and campaign AOV has increased 18% year over year.

We’re excited to continue building on this momentum—next up: a revamp of core automated flows to boost retention and long-term growth.
