Growth of health supplements ecommerce

There’s never been a better time for being health
conscious than now. With over 15,000 brick and mortal health supplement stores in the US, it’s clear that self-care and a healthy lifestyle are here to stay. Covid19 further accelerated the need for leading a healthy lifestyle on one end, and accelerated the demand for shopping for health product online on the other.

According to a study, online supplement sales are expected to grow from $5 billion in 2019 to more than $10 billion in 2022 (reaching 19.6% of all supplement sales).

Challenges to be solved for Dietary supplement stores

1. Communicating Product Knowledge

2. Using customer specific information to send hyper-personalised emails

3. Builing a loyal and sticky customer base

4. Building trust

5. Following compliance & regulations

Case for email marketing for dietary supplements

Health Supplement stores are unique businesses in the sense that their products are almost always multi-use and need a customer to keep coming back to refill their products. This makes the case for the role of a robust email marketing program to make the retention marketing funnel stronger. As email marketing is able to drive high repeat purchases through automations that are specific to customer behaviours, profiles as well as create constant product recall through campaigns, retention marketing for health supplement stores is a no brainer.
In this report, we will highlight how we at Hustler Marketing helped 6 of our health supplement store clients harness the most of email marketing and even SMS marketing to grow their business several times over in a short period of time.


How did we achieve great results for supplement stores through a strategic approach to email marketing?


Leverage customer information for hyper personalized emails

Different customers require different products based on their personalised data like age, gender, lifestyle, preexisting conditions, allergies and other information. Gathering this data is a priority for dietary supplements to help target the right segments and have relevant emails for all. Some ways the stores can gather this data is by building custom popups, using quiz popups using a third party app like, past purchase data or simply by conducting a survey in a previous campaign.

For Nutrachamps, we send survey emails like these ever so often.


Educate, nurture and convert
It’s very important to educate your customer about the product as the world of supplements can be vast, technically confusing or simply not enough credible information may exist. For most of our clients, we rely on creating emails with deeply researched information about a certain range or a particular product. This helps educate the customer and helps them decide whether a particular supplement is right for them. For stores like Nature’s Finest, selling hundreds of products with multiple use cases, precautions and how-tos’ don’t perform so well for spinning sales, at least at the first instance, but they work on warming up/ nurturing the audience.

How Sun Warrior sold out their LEAST Selling product with a single campaign!

For this Dietary supplement brand, we created an informative yet fun and engaging campaign about nothing else but Beetroot Powder – a product that usually doesn’t sell well for this client. One hour after the campaign went out, Sunwarrior sold out all their beetroot powder tubs! Not only that, the client was overwhelmed by the volume of messages they started receiving demanding for this product to be back in stock.


Drive higher revenue and extend CLV through crosssell & upsell flows and exciting campaigns
Most supplement stores sell a variety of products and many of these are complementary products and this fact needs to be baked in when designing flows for dietary supplement stores. For example, a customer that buys anti-anxiety soothing pills may also be interested in anti-anxiety gummy bears and so on.
1. Upsell Flows
For store Dao Drops, we built 3 such flows to create such upsells.
2. “Frequently Bought together” nudge
Another softer version of an upsell is where we added a block about “Frequently Bought Together” nudge next to a category of products within a campaign email.
3. Exciting offers and promo arcs

We sent out a strategic number of campaigns at a frequency that drove the most results. Some of the campaign hooks we focussed on were:
1. Buy 1, get 2 free Promo
2. Curation of Gifts based on occasion
3. Share your experience contest


Drive repeat purchases through automated subscription and replenish email flows
For an industry like dietary supplements, replenishment is the key. Once a customer buys a product, they typically need to keep buying it at a regular cadence. That’s where subscription and replenishment flows come in handy to automatically remind the customers to refill their product at a certain cadence taking into account factors like who uses the product, how often they have been using it, how long before it typically runs out.


Following compliance while ensuring effective messaging

The world of Dietary supplements usually comes under FDA regulations and marketers need to strictly follow compliance. We ensure that all emails that we work on for supplement stores are FDA-compliant and taboo words like “cure” are avoided.

Having copywriters with a legal background who’re on top of such nuances (as we do) helps keep our emails above board, and yet effective.

That said, where traditional online advertising falls short for advertising supplements, emails do allow some leeway in using content that’d be otherwise gated on other platforms. This is where we use our storytelling skills and use of customer testimonials to be able to communicate certain attributes which would be under the radar on another platform.


Building trust

With the growth in supplement stores all over the internet, some of which are admittedly spurious, it’s more crucial than ever for a supplement store to establish trust and credibility.

We help our clients build and retain this trust through 2 pillars of: 1. Honesty 2. Not overpromising 3. Displaying genuine customer testimonials.

Results in numbers

The stores were evaluated based on the following 7 criteria

  1. Average Email Revenue %
  2. Yearly growth of store vs email revenue
  3. ROI from spends on email marketing

Average Email Revenue
Between the 7 stores, the average email revenue % of the total store revenue was 28.9% since they joined us. Point to note is that for one of the stores, Nature’s Finest, the email revenue was 7% , but that is because a huge chunk of the client store revenue comes from ads and hence the email % is lower in comparison. However, this client drives an upward of 7 figure revenue from email.
growth in annual email revenue
While the stores grew an average of 31% between June ‘20-May 2021 and June ‘21 to May ‘22, the email revenue in this period grew at an average of 125% meaning the growth of email revenue far exceeded the overall store revenue growth trajectory.

Email growth within 3 months after Hustler Marketing
