Email, SMS and WhatsApp
Acquisition costs are rising. Customers aren't coming back.
We run email, SMS and WhatsApp for ecommerce brands, turning browsers into buyers, and buyers into customers for life.
Trusted by
Most ecommerce brands have the basics in place.
Flows are live. Campaigns go out every week. A pop-up collects emails, and SMS or WhatsApp is ticking along in the background.
On the surface, it looks fine.
Underneath, each channel usually runs on its own. Email sends a promotion, SMS sends the same one an hour later, and nobody has worked out why people buy once and disappear, or what would bring them back.
Klaviyo's dashboard says email is making money, so it's hard to argue with. But attributed revenue is easy to inflate, and it won't tell you whether customers are buying more often.
We plan email alongside SMS or WhatsApp, around how your customers buy, and we measure the work by repeat purchase rate and lifetime value.
What clients say
Summiteer Media took over our email campaigns in the lead-up to what became a record-breaking Q4 for our business. In November 2025 alone, we achieved 200% year-on-year growth in email revenue.
Tariq KazemiFounder, BLD BROWorking with Louis was an immediate yes for me because I could tell he was going to work on the project. I could tell he's very switched on, and obviously with his background as well he's very, very intelligent and knowledgeable.
Bruno MustoneFounder, ClearO2A huge asset to our email marketing. We're always aligned. His reports provide clear, valuable insight, and his guidance on when to run specific emails has been incredibly helpful. We would absolutely recommend him.
Naomi MurphyMarketing Manager, Solar BuddiesHad a really great experience with Summiteer Media when I needed help with my Klaviyo and email marketing flows. Louis is a great guy, super responsive and helped solve our issues quickly. It's evident they're super knowledgeable on the D2C landscape. Highly recommend.
Fran GresswellFounder, Riviera Iced TeaYou've already paid for these customers.
Every customer on your list came through an ad, a search or a referral, and most of them cost money to reach. When they buy once and go quiet, all that spend has bought you one order.
Email, SMS and WhatsApp reach the same people again without an auction. No bidding, and no algorithm deciding who sees it. The list is yours, and it gets more useful the more you learn about the people on it.
Paid reach
- You bid against other brands for every view
- The platform decides who sees it
- Stops when the spend stops
Your list
- You pay the platform, not an auction
- Everyone who opted in can get it
- Stays yours
Our job is getting the people still browsing to buy, then getting the second order, and the third.
What we actually do
We take on your email in full, alongside SMS or WhatsApp, from the strategy and build to the weekly running and the reporting. Think of us as your in-house team for both, without the hiring.
Strategy and planning
We start with an audit of your setup and find where revenue is slipping, then plan which messages go by email and which by SMS or WhatsApp.
Email
Email does most of the heavy lifting. We build your 8 to 12 core flows, from welcome to winback, then plan, write, design and send your weekly campaigns.
SMS
For messages that need to land fast: cart recovery, launches, restocks and deadlines. Planned alongside email, so nobody gets the same message twice.
WhatsApp
More personal, and customers can reply. We set up opt-in, templates and flows for drops, restocks and VIP offers, tied into your email.
Most brands pair email with either SMS or WhatsApp, rarely both. We'll help you pick the one that suits your customers and products.
Reporting and optimisation
A monthly report that shows what's working and what isn't: your strongest and weakest campaigns, how many first-time buyers came back, and what we'll test next, whether that's timing, offers or which channel a message goes on.

How we're different
You work directly with the founder
You won't be handed to a junior account manager. I'm your main contact. I set the strategy and oversee the work, so you get quick answers from someone who is accountable for the results.
We report on what grows the business
We won't promise "10x email revenue in 90 days", because Klaviyo's attributed revenue is easy to manipulate. We track repeat purchase rate, customer lifetime value, cohorts and profit. When those go up, the revenue follows.
No long-term contracts
We work month to month. If it isn't working, you're not stuck. Most clients stay because the results are there.
Why our clients stick around
I've had no bad experiences with Louis at all in the time that I've spent with him, and I have had many, many, many bad experiences with other agencies.
Bruno MustoneFounder, ClearO2
We tried various agencies, various contractors, and hadn't seen any particular changes. Nothing was setting the world on fire. The results have been amazing. Nothing short of amazing.

Frequently asked questions
Will this work for my niche?
Retention isn't only for consumables brands. Whether you sell supplements, fashion, homewares or something else, if you want customers to come back, we can help.
The approach changes by category. Consumables brands focus on replenishment timing. Fashion is built around seasonal drops and new arrivals. Homewares often depends on occasions and gifting. We plan your email and SMS or WhatsApp around how your customers actually buy.
Should I use SMS or WhatsApp?
Usually one or the other. Most brands pair email with either SMS or WhatsApp, depending on where their customers are and what they sell, and very few need all three. We'll tell you which makes sense for you on the first call.
What size brands do you work with?
We typically work with brands doing £50k or more a month, which is usually when repeat customers start making a real difference to growth.
If you're below that and serious about growing, we're still happy to talk and see if it makes sense.
What's the minimum commitment?
Rolling monthly, so you can cancel at the end of any month.
If it isn't working, you're not stuck in a long contract.
How quickly will I see results?
There are usually quick wins in the first 30 days: flow fixes and campaign improvements that bring in revenue straight away.
The bigger gains, higher LTV and repeat purchase rate, build over three months or more.
Do you guarantee specific results?
No. Every brand is different, and we won't make promises we can't keep.
What we do have is proof that our approach works. And if you're not happy with the results, you're free to stop.
What do you need from us to get started?
An onboarding form, your brand assets, and access to your email and SMS or WhatsApp platforms.
After that, you can be as involved as you like. Some clients want input on every campaign. Others prefer to approve what we create and let us get on with it.
How is this different from other email agencies?
You work directly with the founder. There are no handoffs to junior staff and no account managers who never touch your account.
The person you speak to is the person working on your strategy, which means faster responses and someone who is accountable for the outcome.
What does this cost?
We have packages for different stages and needs. We'll talk through pricing on the call once we understand your setup and goals.
