Our sister brand Oaks took Barimelts from a monthly newsletter to a full lifecycle email architecture in late 2024. Today Barimelts is generating $0.15 revenue per recipient, more than 2x the industry average of $0.06, with campaigns converting at 0.368%, above industry benchmark. These are Oaks's results from email work alone. Barimelts has since become a combined Webtopia and Oaks client, but the numbers in this case study predate that. We're publishing them because they show what proper email architecture looks like for a DTC supplements brand.

Most DTC supplements brands run a monthly newsletter and call email a channel. The brands that actually compound treat email as a system: a lifecycle architecture that catches every customer at every moment that matters, with campaigns as the ongoing layer on top of that foundation.

Barimelts is one of those brands. The work that took them there was led by Oaks, our sister agency, before Barimelts became a combined Webtopia and Oaks client. This is the case study on what changed when their email programme moved from a newsletter to a full-funnel system, the verified numbers it has delivered, and what the broader connected motion now looks like.

About Barimelts

Barimelts produces high-quality, melt-in-your-mouth vitamins specifically formulated for bariatric patients. The brand is built on clean ingredients, ease of absorption for post-surgery customers, and long-term wellness. It has become a trusted name in post-bariatric supplementation.

The category is interesting commercially. Bariatric supplements are not an impulse purchase. The customer is making a clinical decision with real consequences for their recovery, and they are loyal once they find a brand that works for their body. This makes email and retention disproportionately valuable for the category, because the cost of acquiring the right customer is high but the lifetime value is significant if the brand stays in the inbox without being annoying.

The brief

When Oaks started working with Barimelts in late 2024, the email programme had three structural problems.

The lifecycle flows were outdated and were not driving meaningful revenue for the brand. They existed, but they were doing the equivalent of running a small shop at the side of a busy road, not the systematic catch-and-convert work that lifecycle flows should be doing in a $5M+ DTC operation.

The newsletter strategy had not evolved as the brand grew. Content, design, segmentation, and overall messaging strategy all needed to be rebuilt from the ground up to match the level the brand had reached.

And after a recent rebrand, every email needed to match the new, elevated aesthetic. The customer experience inside the inbox was not yet aligned with what the brand had become outside it.

What Oaks did

Two pillars, executed over the engagement. Both run by the Oaks team.

Lifecycle flow buildout. Oaks built a comprehensive suite of email flows from the ground up: welcome, post-purchase, winback, replenishment. Each one was designed to provide customer touchpoints at key stages of the journey. Welcome handles the first impression. Post-purchase converts a first-time buyer into a loyal customer. Replenishment captures the natural reorder moment for a consumables-driven business. Winback gives a second chance to lapsed customers before they churn permanently.

This is the architecture that most DTC supplements brands either skip entirely or implement superficially. Done properly, it is the single biggest lever for moving email from a marginal channel to a structural revenue driver.

Campaign strategy and execution. Once the foundational flows were live, Oaks transitioned into managing ongoing campaigns. What was previously a monthly newsletter became a robust mix: blog roundups, product spotlights, promotions, and educational content. The campaign cadence is now built around the customer, not around the calendar.

The verified results from the Oaks email work

Two numbers tell the story.

$0.15 revenue per recipient. Across all email marketing activity, Barimelts is generating $0.15 of revenue per recipient. The industry average, as measured by Klaviyo benchmarks, sits at roughly $0.06. Barimelts is delivering more than 2x the industry average on the single metric that matters most for email profitability.

0.368% average campaign conversion rate. Above industry benchmarks for the supplements category. This is the metric that proves the campaign content is doing real work, not just being received politely.

The forward focus on the email side is on scaling segmentation, deepening personalisation, and optimising flows to keep pushing long-term retention and customer lifetime value upward. Email at this scale is a compounding asset, not a one-off campaign engine.

What this means for DTC supplements brands

Most DTC founders worry about acquisition first and treat retention as a secondary motion. The numbers usually disagree.

A brand acquiring customers at a $40 to $60 CAC can only sustain that acquisition cost if the average customer comes back two or three times in the first 12 months. That repeat behaviour is not driven by the product alone, however good it is. It is driven by the architecture that catches the customer in the inbox at the moments they are most likely to buy again. Post-purchase. Replenishment. Winback at the consumption window.

The Barimelts case is what proper email architecture looks like in practice. The brand is now operating with an email programme that generates more than 2x the industry-average revenue per recipient, with campaigns converting above benchmark, on a category where lifetime value matters more than headline ROAS.

The bigger picture: connected acquisition and retention

The results above came from Oaks's email work alone. They predate Webtopia's involvement with Barimelts.

Barimelts has since become a combined client. Webtopia runs the paid acquisition side. Oaks continues to run the email and retention side. The two operate as one motion with one reporting view.

This is the structural reason Webtopia and Oaks exist as connected sister agencies. Most DTC brands at $5M to $30M run their acquisition agency and their email agency in separate silos, with separate calendars and separate accountability. The brands that compound run them as one. The Barimelts case is what one half of that connected motion can deliver. The next chapter is the combined view.

What to take from this

If you are a DTC founder in supplements, wellness, or any consumables-led category, three things from the Barimelts case are worth carrying into your own programme.

First, a monthly newsletter is not an email strategy. It is a content cadence. The strategy is the lifecycle architecture underneath it, the flows that catch the customer at every meaningful moment.

Second, the metric that matters is revenue per recipient. Open rates and click rates are diagnostic. Revenue per recipient is the commercial output. If your number is at or below the $0.06 industry average, the architecture is the lever, not the send volume.

Third, the brands that scale are the ones treating retention as a permanent system, not a project. Build the flows once, then keep optimising the campaign layer on top of them. That is what compounds.

Where to go next

If you want to evaluate your own email programme against the architecture in this case study, the team at Oaks runs Klaviyo audits for $5M+ DTC brands. If your acquisition motion needs to be solved alongside the retention motion, book a call with Webtopia and we will walk you through the connected diagnostic.

Frequently asked questions

What is a good revenue per recipient for DTC email?

Industry average for email and SMS revenue per recipient sits at roughly $0.06 in 2026. Brands operating with a strong lifecycle flow architecture and segmented campaign programme typically deliver $0.12 to $0.20 per recipient. Anything materially below $0.06 is a signal that the underlying architecture, not the campaign cadence, is the problem.

What flows should a DTC supplements brand have?

The four foundational flows are welcome, post-purchase, replenishment, and winback. For consumables categories like supplements, replenishment is the single highest-leverage flow because the consumption window is predictable and the natural reorder moment is the highest-intent moment in the customer journey.

How long does a full email rebuild take?

For a $5M+ DTC brand, the foundational lifecycle flows typically take 60 to 90 days to build, test, and stabilise. The campaign programme can begin running in parallel from week one. Optimisation and segmentation are ongoing work, not a finite project.
