eCommerce email marketing, your highest-ROI channel.
eCommerce email marketing is how online stores turn subscribers into repeat customers, through campaigns and automated flows sent to a list you own outright. Unlike paid ads, you don't rent the audience, which is why email is consistently one of the highest-return channels in eCommerce.
An audience you own.
Algorithms change and ad costs rise, but your list is yours. We help you grow it and earn from it month after month, with no media spend in the way.
Built on permission and data.
We do email the right way: permission-based and segmented, in line with UK marketing rules, so you land in the inbox and protect your sender reputation.
Email isn't dead. It's your most profitable channel.
If you're not running email properly, you're leaving money on the table every single day. Social reach is borrowed and ad costs keep climbing, but email reaches people who already chose to hear from you, and it does it for next to nothing. For most eCommerce brands it's the single highest-return channel they have, and it's never too late to start.
You own your audience
No algorithm, no rented reach. Your list is an asset you control, and nobody can take it away.
The highest return in marketing
Email consistently delivers one of the strongest returns of any channel, often many times what it costs to run.
It sells on autopilot
Set the flows up once and they work around the clock, recovering carts and welcoming buyers while you sleep.
It builds loyalty and repeat sales
Email turns one-time shoppers into regulars, lifting repeat purchases and customer lifetime value.
It's measurable and yours
Clear data on exactly what works, with no platform standing between you and your customers.

A quick health check. If you recognise these, there's money sitting unclaimed in your list.

5 red flagsYou send the odd newsletter, but there's no real plan or calendar behind it.
You have no automated flows, so abandoned carts and new subscribers slip away.
Open and click rates are sliding, and more emails are landing in spam.
You blast the same email to everyone, with no segmentation or personalisation.
You can't see what email is actually earning, so you treat it as an afterthought.

What online retailers ask us before choosing an email marketing agency.
What does an eCommerce email marketing agency do?
An eCommerce email marketing agency plans, builds and sends the campaigns and automated flows that turn your subscribers into repeat customers. That spans strategy, list growth, segmentation, design and copy, automated flows like abandoned cart and welcome series, deliverability and reporting, all aimed at growing revenue from a channel you own.
How much does eCommerce email marketing cost?
It depends on how much you need, from setting up core flows to running a full campaign calendar. We keep pricing flexible and transparent inside a monthly retainer, with no hidden fees. Book a call and we'll scope it and give you a clear figure.
Which email platform do you work with?
We work with the leading eCommerce email platforms, including Klaviyo and Mailchimp. If you're already set up, we'll work in your account. If not, we'll recommend and configure the right platform for your store and goals.
What automated flows should my store have?
At a minimum: a welcome series, an abandoned cart flow and a post-purchase flow. From there, browse abandonment, win-back, replenishment and VIP flows add more. These run automatically in the background and often become the highest-earning part of an email programme.
Can email really make £35,000 from one send?
Yes, that's a real result one of our clients saw from a single, well-timed campaign to an engaged segment. It isn't a typical or guaranteed figure, results depend on your list size, offer and engagement. But it shows the upside when the strategy, segmentation and timing are right, and email is consistently one of the highest-ROI channels in eCommerce.
How do you grow my email list?
With well-designed sign-up forms, pop-ups and lead magnets that give people a genuine reason to subscribe, plus capturing subscribers from paid and organic traffic. We focus on quality, engaged subscribers who buy, not just a bigger number.
Will you handle the design and copy too?
Yes. We handle the whole thing: strategy, copywriting, on-brand design and the build. Your emails arrive looking sharp and reading well on mobile, with no extra work on your side.
