Supplement brands often use paid social to reach new customers, but relying too heavily on one platform can make long-term growth harder to sustain. Mister Jones faced this challenge as it looked for a new way to support growth beyond Facebook ads. Email offered a way to build stronger customer relationships after acquisition and maintain engagement over time. In this email marketing case study for supplement brands, we look at the challenge Mister Jones faced, the strategy we developed using automation and educational content, and how it contributed to a 45% increase in campaign revenue.

Mister Jones was looking for ways to scale its business while improving both customer retention and acquisition. Facebook was an important part of the brand’s marketing mix, but building stronger engagement outside the platform would give the team another way to maintain customer relationships over time.
For e-commerce brands, the balance between email marketing and paid social comes down to the role each channel plays. Paid social can help brands reach and acquire new customers, while email provides a direct way to continue the relationship with people who have already chosen to engage.

We focused on making email a more dependable part of the brand’s wider retention efforts, with a clearer role in supporting customers after acquisition.
We refined Mister Jones’ existing flows to better respond to different stages of the customer journey and contribute more consistently to revenue. This gave automated emails a clearer purpose within the wider program, while regular email campaigns could focus on keeping customers engaged over time.
Alongside the automation work, we developed educational content that gave customers useful information about their products and routines. For a subscription-based supplement brand, this created an opportunity to improve product understanding while keeping the brand relevant in the time between subscription orders.
Together, these changes gave Mister Jones a more structured email program that could support both immediate campaign performance and longer-term subscriber relationships.
The changes led to measurable improvements across both campaigns and automated flows:
Taken together, these results showed stronger email performance through increased customer engagement and revenue, making email a more valuable part of Mister Jones’ overall retention strategy.

For supplement brands, email can strengthen the wider marketing mix by giving customers useful reasons to stay engaged after the initial purchase.
Together, these areas can help brands make email a stronger part of their customer retention strategy, with campaigns and automation each playing a clear role.

As brands scale, finding reliable ways to stay connected with existing customers becomes increasingly important. Email gives e-commerce teams an opportunity to build those relationships through relevant campaigns, lifecycle automation, and content that continues to provide value after acquisition.

Brands can strengthen owned channels such as email and SMS, improve retention, and build direct customer relationships that continue beyond paid social acquisition.
Email can encourage repeat purchases and improve retention among existing customers, reducing the need to rely on paid acquisition for every additional sale.
Heavy reliance on paid social can expose brands to rising acquisition costs, platform changes, and limited control over ongoing customer communication and engagement.
Email and paid advertising serve different but complementary roles. Paid ads primarily support customer acquisition, while email can nurture existing audiences, improve retention, and encourage repeat purchases.
Educational content, relevant automations, and subscription-focused communication can help supplement brands maintain engagement and strengthen customer relationships after the first purchase.
