Email Marketing for Hers-Style Brands: What Moves the Needle

Email marketing for direct-to-consumer health and wellness brands like Hers operates differently from standard e-commerce. The audience is skeptical, the purchase decision is personal, and the inbox is where trust either compounds or collapses. Getting it right means understanding the full lifecycle, not just the acquisition blast.

Hers built its email program around clinical credibility and consistent value delivery, not discounts and urgency timers. That distinction matters more than most brand teams acknowledge, and it shapes every decision from subject line to send cadence to what happens after the first purchase.

Why Health and Wellness Email Is a Different Category

I spent several years working with healthcare-adjacent clients at agency level, and the thing that struck me every time was how much the standard playbook broke down. The tactics that worked brilliantly in retail, travel, and financial services either underperformed or actively damaged brand trust when applied to health.

The reason is simple: the purchase decision is intimate. When someone is buying a skincare treatment, a hair loss solution, or a mental health supplement, they are not in the same headspace as someone buying a pair of trainers. The emotional stakes are higher. The skepticism is higher. And the tolerance for being marketed to aggressively is much lower.

Hers understood this early. Their email program is built around information, not persuasion in the traditional sense. They educate before they sell, and they sell by educating. That is not a subtle distinction. It is the whole architecture of the program.

If you are building or managing email for a brand in this space, the starting point is accepting that the rules are different here. The frameworks that apply to general e-commerce, the ones you will find on most email marketing resource pages, need adapting before they are useful.

The Acquisition Sequence: What Hers Gets Right From Day One

Most brands treat the welcome email as a formality. Hers treats it as the first clinical consultation. That reframing changes everything about what goes in it.

A standard welcome email says: here is a discount, here are our bestsellers, here is our social media. A Hers-style welcome email says: here is what we know about your concern, here is the science behind our approach, here is what to expect. The discount, if there is one, is secondary to the credibility signal.

This matters because the welcome sequence is where churn decisions are made. Subscribers who feel immediately sold to in a health context tend to disengage faster. Subscribers who feel informed tend to stay longer, open more, and convert at higher rates when the ask eventually comes.

Early in my agency career, I worked on a campaign for a financial services client where we tested an educational welcome sequence against a promotional one. The educational version had lower short-term click rates and higher long-term revenue per subscriber. The client’s instinct was to run the promotional version because the early metrics looked better. We pushed back. They agreed to run both. The educational version won by a margin that was not close. Health and wellness email follows the same logic, but the effect is even more pronounced because the emotional stakes are higher.

The acquisition sequence for a Hers-style brand should run across at least five emails: a credibility-first welcome, a science or ingredient explainer, a social proof email built around real outcomes rather than generic testimonials, a soft product introduction, and a conversion email with a clear but unpressured CTA. That is the architecture. The execution varies by category and audience, but the logic holds.

Segmentation: Where Most Health Brands Leave Money on the Table

Broadcast email, the kind where everyone on the list gets the same message on the same day, is a blunt instrument. It works well enough in categories where the audience is relatively homogeneous and the purchase decision is low-stakes. In health and wellness, it is close to useless as a primary strategy.

The Hers subscriber list contains at minimum three distinct groups: people who have never purchased, people who are active subscribers or repeat buyers, and people who have lapsed. Each group has a different relationship with the brand, a different level of trust, and a different barrier to the next action. Sending them the same email is not just inefficient. It is actively counterproductive for the lapsed segment, who are likely to disengage further if the first re-engagement attempt feels generic.

Effective segmentation in this category goes beyond purchase history. It includes engagement frequency, product category interest, and where in the health concern experience the subscriber appears to be. Someone who opened three emails about hair thinning and clicked on one ingredient explainer is telling you something specific about their current mindset. An email program that ignores that signal is leaving a significant opportunity on the table.

Personalisation in email marketing is not about inserting a first name in the subject line. It is about sending the right content to the right person at the right moment in their decision process. That requires data discipline and a willingness to build more complex flows, but the return on that investment in a subscription health model is substantial.

When I was growing the agency from around 20 people to closer to 100, one of the consistent findings across client programmes was that segmented email outperformed broadcast by a ratio that made the additional build time look trivial. The brands that resisted segmentation were almost always doing so for operational reasons, not strategic ones. That is a trade-off worth challenging.

Subject Lines and Open Rates: What the Data Actually Shows in This Vertical

Health and wellness email subject lines operate under constraints that most copywriters underestimate. The category is heavily regulated in some markets, which limits certain types of claims. The audience is sophisticated and skeptical of hype. And the inbox is crowded with competitors making similar promises.

The subject line approaches that consistently perform in this vertical share a few characteristics. They are specific without being clinical to the point of being cold. They reference a concern or outcome the subscriber cares about. And they avoid the urgency and scarcity tactics that work in retail but feel manipulative in a health context.

“Why your hair might be thinning faster in winter” outperforms “50% off ends tonight” in this category, not because discounts do not work, but because the audience came to the brand for information and expertise. Leading with information honours that relationship. Leading with a discount signals that the brand thinks of them primarily as a transaction.

Mailchimp’s research on email engagement consistently points to the value of relevance over volume. In health categories, relevance is almost entirely determined by how well the subject line matches the subscriber’s current concern, not how compelling the offer is.

Testing subject lines in this category requires patience. The sample sizes needed to reach statistical confidence on open rate differences are larger than most teams account for, and the results often take a few weeks to stabilise because engagement patterns in health email are slower-moving than in retail. Build testing into the programme structure from the start, not as an afterthought.

Email Design for Health Brands: Calm Authority Over Visual Noise

The design choices in health and wellness email send signals that subscribers process before they read a single word of copy. A cluttered, promotion-heavy layout communicates one thing. A clean, well-spaced layout with clear hierarchy communicates something else entirely.

Hers uses a design language that is deliberately restrained. White space, clean typography, minimal colour variation, and a single clear CTA per email. That is not an accident. It is a deliberate choice to reinforce the brand’s positioning as a credible health provider rather than a promotional retailer.

Email design best practices in general e-commerce often emphasise visual richness and multiple CTAs. In health and wellness, those principles need inverting. Every additional CTA is a decision the subscriber has to make, and decision fatigue in a high-trust category tends to result in inaction rather than action.

The mobile rendering question is not optional in this category. A significant proportion of health and wellness email is opened on mobile, often in private contexts, which means the reading experience needs to work on a small screen without requiring the subscriber to zoom, scroll horizontally, or squint at small text. If the design does not work on mobile, the content quality is irrelevant.

I have seen brands invest heavily in email copy and then watch their engagement numbers flatline because the design was broken on the three most common mobile clients. The copy was good. The design undermined it completely. In this category, design is not decoration. It is a trust signal.

The Retention Programme: Where Subscription Health Brands Win or Lose

Acquisition email gets most of the attention. Retention email generates most of the revenue. In a subscription model like Hers, the economics are straightforward: a subscriber who stays for 12 months is worth dramatically more than one who cancels after two. Email is one of the primary levers for influencing that outcome.

The retention programme needs to do three things consistently. It needs to reinforce the subscriber’s decision to stay by delivering ongoing value. It needs to identify and respond to early signals of disengagement before they become cancellation decisions. And it needs to surface upsell and cross-sell opportunities in a way that feels like a natural extension of the subscriber’s existing relationship with the brand, not a separate sales conversation.

Progress emails are particularly effective in health subscription models. An email that says “here is what consistent use of this treatment typically looks like at the 60-day mark” serves multiple functions simultaneously. It sets expectations, it reinforces the value of continuing, and it positions the brand as a knowledgeable partner rather than a transactional supplier. That is a high-value email to send, and most brands in this space are not sending it.

The cancellation risk signals worth monitoring in email data include a sustained drop in open rate, a shift from clicking product content to clicking editorial content, and a complete stop in engagement over a 30-day window. Each of these patterns suggests a different intervention. A blanket win-back campaign sent to all three groups will underperform a targeted response to each specific signal.

When I was running agency P&Ls, the client programmes with the strongest retention metrics were almost always the ones with the most developed post-purchase email sequences. The correlation was consistent enough across categories that I started treating retention email investment as a leading indicator of programme health, not a lagging one.

Deliverability: The Infrastructure Question That Determines Whether Any of This Matters

None of the strategy above matters if the emails are landing in spam folders. Deliverability in health and wellness email is a particular challenge because the category sits adjacent to some of the highest-spam-volume sectors on the internet. Health-related keywords in subject lines and body copy can trigger spam filters even when the email is entirely legitimate.

The fundamentals of deliverability are not complicated, but they require consistent attention. List hygiene matters more in this category than in most because inactive subscribers damage sender reputation over time. A list with a significant proportion of cold addresses will see inbox placement rates decline gradually, and the decline is rarely obvious until it has already done meaningful damage to programme performance.

Authentication setup, including SPF, DKIM, and DMARC records, is baseline infrastructure. If those are not in place, deliverability problems are essentially guaranteed at scale. Modern email platforms make the technical setup straightforward, but it still requires someone to actually do it and verify it is working correctly.

The content-level deliverability considerations in health email include avoiding certain trigger phrases, maintaining a healthy text-to-image ratio, and ensuring that the unsubscribe mechanism is clean and functional. Brands that make it difficult to unsubscribe in the hope of retaining subscribers are making a category error. Forced retention through friction generates spam complaints, which damage sender reputation far more than a clean unsubscribe would have.

Email and Paid Media: How Hers Connects the Channels

Email does not exist in isolation in a well-run DTC health programme. The relationship between email and paid media, particularly social, shapes how acquisition economics work and how the brand experience holds together across touchpoints.

The interaction between Facebook advertising and email marketing is particularly relevant for brands like Hers, where paid social drives a significant proportion of new subscriber acquisition. The handoff from paid ad to email welcome sequence is a moment where brand experience either continues coherently or fractures. A subscriber who clicks a Facebook ad about hair loss and then receives a generic welcome email about all products has experienced a disconnect that undermines the conversion probability.

The most effective approach is to use the acquisition source and any available signal from the ad creative to inform which welcome sequence the new subscriber enters. Someone who came in through a hair-specific ad should enter a hair-specific sequence. This is not technically complicated, but it requires coordination between the paid media team and the email team that does not always happen naturally.

Early in my time managing large paid search budgets, I saw how quickly revenue could move when the channel handoffs were clean. At lastminute.com, a campaign I ran for a music festival generated six figures of revenue within roughly a day, partly because the landing experience matched the ad promise precisely. The same principle applies to email. When the message is consistent from the first paid touchpoint through the first email, conversion rates reflect that coherence.

There is a broader point here about how health brands think about channel integration. Email is not a standalone acquisition tool. It is the retention and relationship layer that makes paid acquisition economics work. A brand spending heavily on paid social to acquire subscribers and then running a weak email programme is essentially leaving the most valuable part of the funnel underdeveloped. The cost of acquiring a subscriber is fixed. The return on that cost is determined almost entirely by what happens in email after acquisition.

For a broader view of how email fits within a full acquisition and lifecycle strategy, the Email and Lifecycle Marketing hub covers the connected decisions that most channel-specific guides tend to leave out.

Measuring Email Performance in a Health Subscription Model

Open rates and click rates are useful directional indicators. They are not business metrics. In a subscription health model, the metrics that matter are subscriber lifetime value, churn rate by email cohort, and revenue per subscriber over defined time windows. Everything else is a proxy for those outcomes.

The challenge with measuring email in this category is that the purchase cycle is longer and more considered than in retail. A subscriber might open 12 emails, click on three, and convert on the 14th. Attribution models that give credit only to the last-touch email are systematically undervaluing the role of the earlier educational emails in building the trust that made conversion possible.

I spent a significant part of my agency career arguing with clients about attribution models, and the consistent problem was that last-click attribution made acquisition channels look more valuable than they were and retention channels look less valuable. In health subscription email, that bias is particularly damaging because it leads to underinvestment in exactly the sequences that are doing the most work.

A more useful measurement approach is to track cohort behaviour over time. Subscribers who entered through a specific sequence, what is their 90-day retention rate? Their 6-month revenue? How does that compare across different welcome sequences, different segmentation approaches, different send cadences? Those questions are harder to answer than “what was the open rate on Tuesday’s email,” but they are the questions that actually inform programme investment decisions.

The ongoing debate about email’s relevance as a channel tends to miss this point entirely. Email is not declining as a channel. Poorly measured, poorly segmented, broadcast email is declining. Thoughtfully built lifecycle programmes in categories where trust matters are performing as well as they ever have.
