Klaviyo Silver Partner
Klaviyo Agency UK
Klaviyo email and SMS built and run as a revenue system for UK eCommerce brands doing £15k to £100k a month. Flows, segmentation, sign up forms and campaigns, engineered by a Klaviyo Silver Partner and measured in revenue, not opens.



£11k → £117k
Monthly email revenue, The Corkbox
Most Klaviyo accounts are not underperforming because of the platform. They are underperforming because of the system.
Flows that were set up once and forgotten
A welcome series and a basic abandoned cart, built years ago and never touched. The automations that should earn while you sleep are barely switched on.
One list, one message, everyone
Every subscriber gets the same campaign whether they bought yesterday or have never bought at all. Engagement drops, deliverability follows, revenue stalls.
A list that is not growing
Sign up forms convert at a fraction of what they should, so every month you pay to acquire visitors and let most of them leave without an email address.
What is included
Your Klaviyo account, built properly.
01
Account audit and list cleanse
Your account scored on list health, flow coverage, segmentation and capture. Unengaged profiles cleaned so your sender reputation works for you.
02
Segmentation by purchase intent
Audiences built around what people have bought, browsed and opened, so every send reaches the right customers at the right time.
03
Automated flows
Welcome, browse abandonment, cart and checkout abandonment, post purchase, replenishment and win back, built to run without anyone pressing send.
04
Sign up forms that capture
Pop ups and embedded forms designed and tested to turn more of your existing traffic into subscribers.
05
Campaign calendar, designed and sent
A planned calendar of campaigns built around your launches and trading peaks, written, designed and sent for you.
06
Weekly reporting against revenue
Email attributed revenue, flow performance and list growth reported every week in plain English. Not opens and clicks on their own.
Results
What a properly built Klaviyo account does.
Across our clients, email typically attributes 35 to 40% of total revenue once the system is built.
How it works
Audit first. Build second. Then scale.
Audit
Your Klaviyo account, store and sign up capture reviewed in full. You get the diagnosis and the order to fix things in, whether we work together or not.
Build
List cleansed, segments built, flows rebuilt from the ground up and forms redesigned. The foundations go in before the campaign volume goes up.
Run and scale
Campaigns designed and sent on a set calendar, flows tested and improved, and everything reported weekly against revenue.
Why JHA Media
A Klaviyo partner that thinks like an operator.
Klaviyo Silver Partner
JHA Media is a Klaviyo K:Partners Silver partner, certified through Klaviyo Academy as a Klaviyo Practitioner.
Engineered, not guessed
Run by Ben Evans, a Lean Six Sigma Master Black Belt. Measure the baseline, find the constraint, change one variable, verify the result.
You work with Ben directly
No account managers and no hand offs. The person who audits your account is the person who builds and runs it.
Email as part of the system
Email is built alongside your store and your ads, so the flows convert the customers your acquisition is already paying for.
"What an experience from start to finish. So much experience and knowledge, we worked with Ben to help create our new website and to support our new eCommerce business. So impressed with all aspects, his patience with the countless changes we wanted to make. Really looking forward to continuing to work with Ben."
"Ben is an absolute pleasure to work with and I'm very glad to have him on that end of the business."
"We worked with JHA Media over the past few months to manage and scale our email marketing across multiple markets, and the results have been exceptional. Ben brought a level of commitment and professionalism that genuinely felt like having an in house team member rather than an external partner."
"Using their ACR Growth Method we have seen measurable improvements across every area of our eCommerce business, from acquiring more qualified customers, to converting them more efficiently, and increasing retention. The results speak for themselves."
"He becomes a second brain, almost like a business partner, and helps me to stay calm and remain focused on the goal. Through the 90 days programme, my business is in a much stronger position. I cannot recommend him enough."
"Fantastic results from JHA, highly recommend if you are ready to see real results. The quality of leads has resulted in a massive increase in profit. We would not work with anyone else."

"The only company I have used and experienced real results, real conversions. Sales have increased, traffic is great. A company that truly exceeds expectations."
"Before working with JHA Media, our email marketing was dead, with barely any revenue coming in. In just a short time, Ben and the team completely transformed it. Now email is one of our top revenue drivers."
"I was very sceptical when I started. They seemed to really understand the situation and explained how they would find leads that actually convert. It has turned out to be a fantastic decision."
"Ben honestly feels like an extension of our business. We have seen incredible growth over the last few months and everything we do now is strategically driven by Ben with his expertise."
"The experience I have had with them as a company has been impeccable. For a service like this I would expect to pay at least double what I was charged. 10/10 all round."
"They offer the best advice and service and I will 100% be using them frequently. Do not know what I would have done without Ben and the JHA Media team."
