Email—Your Owned Digital Territory: Unlike social media, where algorithms dictate reach, email offers unrestricted space to connect with customers. Leveraging this owned channel can significantly enhance ecommerce business success.
While 62% of email marketers spend two weeks or more on a single email, the average person spends just 10 seconds reading it.
10 seconds. For something that takes you weeks to create.
And that's if they even open it in the first place.
Most ecommerce brands struggle to get their emails opened, let alone clicked—which means that they fail to transform email marketing into a revenue-generating machine.
So, we're ditching the theory and diving headfirst into real-world results. From coffee in Vietnam to sex toys in India to bidets in the US—think of this post as a fireside chat with ecommerce online store owners who are making bank with email.

Do Email Marketing Campaigns Even Work For Ecommerce?
Social media platforms are dominated by algorithms, and your reach can be limited, but email is an owned channel.
You control the content, the timing, and the audience.
This means a direct line to your customers to build relationships, nurture leads, and drive sales—all on your own terms.
No middlemen. No algorithm overlords.
Still need convincing? Feast your eyes on these numbers:
- ROI king. Litmus found that the ROI on email marketing in the ecommerce industry is a staggering $45 for every $1 spent. Need we say more? Cha-ching!
- Increased spending. According to Entrepreneur, consumers spend 128% more when shopping from emails compared to other digital marketing channels.
- Customer favorite. Nearly half of global internet users with mobile devices actually prefer to receive business communications via email. They like it! They want it! They expect it!

Three Brands, Three Niches, One Powerful Tool
We're sitting down with ecommerce entrepreneurs who are absolutely killing it with email: Ritesh D. Ritelin of Manzuri, John Grant of Premier Bidets, and Mimi Nguyen of Cafely.
Email marketing ecommerce case study #1: How Manzuri became a $500,000-dollar brand
Manzuri, an Indian “pleasure tech” company, is generating serious revenue—approximately $83,000-$90,000 of their $460,000-$473,000 total—by using email to build a thriving community and drive sales.
That means 18%-19% of their revenue comes from email marketing!

I sat down with Ritesh D. Ritelin, the co-founder of the startup, and we talked for an hour about Manzuri’s success as an ecommerce store driven by strategic email marketing efforts.
The challenge: Saying no to paid marketing
For the first six to eight months, Ritesh says that they just did social media:
I was leading performance marketing and growth at a company called Milam Over Air.
Basically only if we put in money, did we earn money. It was a very venture-backed environment, very typical of how venture-backed environments work.


So, what was the problem?

We did a lot of things, and we had a very good journey of growth, but it was all dependent on how much money we were pumping in.
Fundraising, putting in money, and making enough money to raise the next round…
…and the biggest thing I learned was that paid marketing is something that is really annoying because the founder’s mental health becomes connected to the ROI of the brand.
A bold, but well-informed decision, Ritesh was clear that he didn't want a direct correlation between performance marketing, his business, and his mental health.
He knew there had to be a better way—a way to build a sustainable business without the constant stress of paid acquisition.
The solution: Email first, everything else second
I was like, “Let’s not run any ads.” That was our kind of very clear fundamental value. We don’t spend money.


You’re clear you don’t want to spend money to make money. And that’s where email marketing comes in for you?

It’s not that email marketing was something very new for us… however, I never thought that it would be this useful and valuable for a small brand until I started doing it.
Manzuri slowly beefed up its email list and hunkered down with exceptionally good email content.
They focused on building a strong online presence through SEO and engaging content on platforms like Reddit. Instead of bombarding their email subscribers with constant sales pitches and promotions, they focused on providing value first.
We started with a newsletter.
We were like, why are people reading our newsletter where we’re talking about, you know, sexy summer playlists and five movies to watch with your partner?
We’ve been talking about these things, and we’re getting sales from this.

This unexpected success led to a key learning:
In categories where lots of education has yet to be created, email works very well.
👉🏼Manzuri’s email marketing playbook:

Okay, so sexual wellness in India is certainly ripe for education, and people prefer education-driven content in this niche. My next question is, what’s your very first step after you discover this?

The first thing that I would recommend is setting up very strong email flows.
So the basic flows, of course, are welcome emails and follow-up emails like shopping cart abandonment, abandoned checkout, product abandonment, and stuff like that, which most people do.
However, there are other flows, such as replenishment.


What do you mean exactly by “replenishment”?

So, if I’m selling a supplement brand supplement product, let’s say a thirty-day dose, you know, I need to consume it every 30 days; I need to buy a refill.
On the 28th day, we’ll send out an email saying that it’s time for you to refill your product. And sometimes I’ll add incentives.
Like, get 10% off if you purchase in the next 24 hours. So it’s not just a reminder and a nudge. There is a scarcity element. But this is automated. I don’t send this email out manually every time.

What’s another example of an email template or flow you automate?

Reviews automation. If you received a product, it’s been seven days since you received the product, you’ll receive an email that says, “Hey, please write us a nice review. We’re a small bootstrapped brand and a review could mean the world to us.”
Small stuff like that. There are about 20 to 30 such journeys that you can create.
You don’t have to create them in one go, but build them over time. And the more personalized an email is, the higher the open rates will be and the higher the conversion rates will be.


You’ve got your target audience hooked, and you’ve set up your flows. What’s next?

The first seven to 14 days are all that matters after a customer has given me their email address. 60%-70% of purchases will happen within the first seven days.
The remaining 20%-30% of purchases will happen in the next seven days. As for the next five to 10 days, maybe you get results, but they slow down significantly.
So, the first 14 days are what you need to optimize for.

So, apart from the metrics, what have you, as a founder, learned about email marketing?

That research part is always step one. Let’s say I’ve got five competitors, I need to know exactly what they are doing.
However, I need to look at industries that are a little bit more mature than my industry. Look outside your industry; a contrarian perspective allows you to learn from more established markets.
Don’t just look at your direct competitors.

That's very interesting actually, because the first thing that you hear when you're doing research is like, research your direct competitors and fill the gaps.

We need to research competitors that are in another industry and make sure that the industry is four to five years ahead of you in terms of maturity.
So, Manzuri is “pleasure tech,” only three or four years mature.
A brand that’s into period care would be three years or four years ahead of pleasure tech. And maybe a skincare brand or something would be even three years farther ahead in terms of maturity.
So we need to understand what all of them are doing.
And from that, we need to understand that, okay, our customer needs a certain thing.
The other thing Ritesh highlights is constantly experimenting: A/B testing, monitoring customer data to improve click-through rates, and investing in the right marketing tools.
The results
Manzuri's email-first strategy has translated into tangible business growth. Here's the breakdown:
- Serious revenue. Manzuri makes a lot of money from email marketing—roughly 20% of their yearly total.
- Lower acquisition costs. Optimizing email flows to nurture and convert subscribers has successfully reduced Manzuri's customer acquisition costs. They're getting new customers cheaper, which is key to growing steadily.
The marketing automation tools Manzuri swears by
What's the tech—email automation and email marketing platform—behind Manzuri's success?
This is what Ritesh and I talked about:

So what tools do you use to make sure that all of this falls into place?

We only use Klaviyo; we don’t use anything else. It has the best data segmentation features.

Why Klaviyo? I know it's very popular, it's one of the best tools on the market, but why for you specifically?

Firstly, Klaviyo is partly owned by Shopify, so there’s a very deep data integration between the two brands.
When you look at the dashboards, the analytics, the way the segmentation works, and the flows you can create, nothing is more advanced today than Klaviyo is when it comes to email marketing.

Email marketing ecommerce case study #2: Premier Bidets clean up with email
Premier Bidets, a US-based ecommerce company specializing in, well, bidets, demonstrates how targeted email campaigns can be a powerful driver of revenue and customer loyalty.

The challenge: Turning browsers into buyers
Premier Bidets knew their brand was well known, but they needed a better system for turning interest into purchases.
Their goal was to find a strategy to connect with their audience, grow their leads, and convert them into customers.
The solution: Personalized emails that make a splash
"At Premier Bidets, we’ve seen just how powerful email marketing can be when it’s personalized and relevant," says John Grant, CEO of Premier Bidets, who I spoke with over email.
By segmenting our audience based on things like past purchases, browsing habits, and how they interact with us, we’re able to send content and special offers that really speak to each customer’s needs.

When did you realize email's potential as an organic channel for driving conversions?

We really saw the power of email marketing when we started experimenting with segmented email lists.
Sending personalized offers that were tailored to each customer’s preferences led to a noticeable increase in both engagement and conversions.
Over time, we fine-tuned our approach by tracking key metrics like click-through rates (CTR) and sales conversions, which helped us improve our messaging and offers.
The big turning point came when we realized how valuable customer retention emails are—focusing on encouraging repeat purchases and building loyalty, which helped boost our long-term revenue.

👉🏼Premier Bidet’s email marketing playbook:

What are some email best practices that seem obvious to you but may not be common knowledge?

While promotional emails are essential, we’ve discovered that sending insightful, value-driven content helps build trust and increase engagement.
We share stories about the people behind our products or provide educational content like cleaning tips and bathroom renovation guides.
This makes our brand feel more personal and connects us with our subscribers on a deeper level, beyond just transactions.
Storytelling in our emails helps differentiate us from generic offers and creates a genuine connection with our audience.

Apart from storytelling, how do you keep your unsubscribe rate low?

We’ve had great success adding interactive elements like polls, quizzes, and embedded product carousels to our emails.
These features not only make our emails more engaging, but they also provide us with valuable insights into our customers’ preferences, which helps shape our future campaigns.
For instance, a quiz about bathroom preferences can lead to personalized product recommendations, resulting in higher conversions.
It’s a fun way to connect with our audience while driving more relevant and effective offers.
The results
While Premier Bidets prefers to keep its exact revenue figures confidential, John acknowledges the significant role email marketing plays in their overall success.
"Email marketing has become one of the most effective channels for Premier Bidets, significantly driving sales," Grant confirms.

Through smart automation—such as welcome emails, abandoned cart reminders, and post-purchase follow-ups—and personalized content, we’ve been able to keep generating sales from past customers.
Plus, the trust and loyalty built through these emails have encouraged repeat purchases, adding steady growth to our revenue over time.
Email marketing ecommerce case study #3: How Cafely brewed a 20%+ revenue increase with email
I connected with Mimi Nguyen, Cafely's founder, over email, and she shared how they've used email to build a thriving business, boost their revenue by over 20%, and share their love for Vietnamese coffee culture with the world.

The challenge: Standing out in a hyper-competitive market
Cafely's goal wasn't just coffee sales—it was sharing Vietnam's coffee culture globally.
Growing up in Ho Chi Minh City, practically every memory has a coffee shop backdrop.
Coffee wasn’t just a drink; a strong cup of coffee in the morning was a chance to connect with family and friends before the day took off.

In a competitive market saturated with established brands, Cafely needed a way to differentiate themselves and connect with their audience on a deeper level.
The solution: Visual storytelling and targeted content

How does email help you retain customers and compete in the coffee market?

Oh, don’t even get me started on how competitive the coffee market is, haha!
In the coffee market, the only way you can stand out is through authentic, personalized experiences (and actual good coffee, of course!)—that’s where email marketing shines.
It’s highly customizable and allows us to create a visual story with each email, focusing on the vibrant coffee culture of Vietnam and the sensory experience that makes customers feel that they, too, are already a part of Cafely’s coffee journey.
For us, email marketing allows connection.

👉🏼Cafely’s email marketing playbook:

How do you create this “visual story” for your products?

Stunning visuals might be that one thing that keeps a potential customer that keeps potential customers engaged rather than clicking away!
We invest in professional photography that showcases not just our coffee beans, but also close-up shots of our coffee being brewed and the finished drinks.
Many brands miss out on this opportunity because they might think text alone is enough to convey their message, but in reality, people are drawn to what they can see first!
When customers see beautiful images of what they love, it sparks desire and drives them to purchase.
And it shows. The product photography on their website, which is then often repurposed for email, is stunning:

The results
Cafely's email marketing strategy has yielded impressive results:
- Significant revenue contribution. "Email marketing accounts for a significant portion of our revenue—definitely over 20%," Nguyen says.
- Increased conversions. By incorporating brewing guides and visually appealing content, Cafely has successfully driven a significant number of first-time purchases through email.
- Repeat business. Email has proven to be an effective tool for fostering repeat business and building customer loyalty.
5 Actionable Strategies You Should Take Away From These Brands
Rather than generic advice about "providing value," here are specific strategies these companies used that buck conventional wisdom.
And to help us understand exactly how they do it, we've also got Ziemek Bucko, senior content manager at Hunter.io, who’s helped 20+ ecommerce brands find their email marketing sea legs.
1. Educate, entertain, and sell without selling
Manzuri, Premier Bidets, and Cafely all understand a fundamental truth: nobody likes being bombarded with constant sales pitches. Instead, they focus on providing value to their subscribers.
Think educational newsletters, curated content, and engaging storytelling.
"The trend that's emerging in email marketing is that you use email to add value to a customer… Keep giving value to them. They will buy on their own," Ritesh explains.
2. Experiment with visual storytelling
Cafely knows a picture is worth a thousand words (and maybe even a thousand sales).
They invest in high-quality photography and create visually engaging emails to capture their audience's attention.
"We believe aesthetics play a very significant role in email marketing," says Mimi Nguyen, founder of Cafely.
And if you want a touch of dynamic email design, GIFs are some of the most visually playful elements to keep your subscribers scrolling.

3. Find the best times to send your marketing emails
Timing is everything, and the best email send times depend on your unique email list.
Premier Bidets and Cafely both emphasize the importance of timing your email campaigns strategically.
"We’ve learned to tap into micro-trends and key moments in our customers’ purchasing behavior," explains John Grant, CEO of Premier Bidets.
BTW, I surveyed 60+ ecommerce store owners to find the best times for sending ecommerce emails:

4. Make full use of email automation tools
Manzuri, Premier Bidets, and Cafely all leverage automation to streamline their email workflows.
"It's just a one-time effort, and it'll give you ROI for the rest of your life," Ritesh says about setting up automated email flows.
Your search for the perfect ecommerce email marketing platform ends here—with our list of the top 10 hottest software on the market:
5. Jump years ahead in your competitor research
The literal million-dollar insight from Manzuri—look at brands at least half a decade ahead of your industry.
For example:
- Pleasure tech (3-4 years mature) is finding its feet in the dark.
- Period care (7-8 years mature) has already found the light switch.
- Skincare (10+ years mature) is running full speed ahead.
Why make the same mistakes your competitors are making right now when you can steal proven strategies from brands that have already figured it out?

Ecommerce Email Marketing in 2025 is a Gold Mine (If You Know Where to Dig)
We've just peeked behind the curtain of three brands crushing it with email. Not theory. Not “best practices.” Real companies making real money by sliding into their customers' inboxes.
The playbook's right here:
- Ditch the “buy now” spam. Send stories that make people forget they're being sold to.
- Let automation handle the grunt work: build solid email flows that convert.
- Turn everyday products into must-read content (if bidets can do it, so can you).
- Stop copying competitors. Look at brands four to five years ahead of your industry instead.
- Make those first 14 days count—that's when 70% of purchases happen.
No paid ads. No algorithm dancing. Just pure, automated profit, churning out $45 for every dollar spent.
