What our clients say
Don't just take my word for it
From brand owners, founders and teams we work with.
“Working with Kayhan has honestly made email way less stressful for us. Before, we were kind of just sending campaigns whenever we had time. Now there's an actual plan behind everything, and it shows.
The communication has been easy, the ideas have been strong, and we're pretty happy with the results we're getting.”
Aaron ChinCEO · Organika
“What I appreciate most is that I don't have to chase anything down. Kayhan and his team are proactive, organized, and always coming to us with ways to improve what we're doing.
They've put a clear system in place for our growth, and everything feels much more organized now.
It honestly feels more like having an in-house team than working with an outside agency.”
Mark JanceCo-Founder · Bey Moss
“We've worked with quite a few agencies over the years, and unfortunately, none of them really delivered what we were looking for.
Since we started working with Kaysun, things have been completely different. Our email channel consistently brings in over 30% of our total revenue, and we've finally got a proper strategy behind everything.
The team knows what they're doing, communication is great, and we're really happy with how things are going.”
Matt CaulfieldDirector of Brand · Maude
“Honestly, one of the best parts has just been the peace of mind. I know things are getting handled, and I'm not constantly thinking about what email we need to send next.
The team takes care of everything, from planning to execution, and it's made running the business a lot easier.
That alone has been huge.”
Emily CarterOwner · Wild Bloom
“Kayhan really took the time to understand our brand before making any changes. Nothing felt generic, and that stood out right away.
One of the biggest improvements was how they approached our customer journeys. Instead of sending the same emails to everyone, they built flows around specific products and customer behaviors, which really helped with our recovery flows.
The strategy has been thoughtful, and the whole process has felt really smooth.”
MichaelCo-Founder · Michael Todd Beauty
“We've worked with other freelancers before, but this has felt much more structured. Better planning, better communication, and stronger ideas.
What I really appreciate is that the team actually takes ownership of things. They're always looking for ways to improve our email marketing instead of just doing the bare minimum.
It's just been a really solid experience all around.”
Jason ColeFounder · Oak & Thread
“Excellent specialists when it comes to backend marketing. The team built high-quality ecommerce emails for our business and really knew what they were doing.
Communication was great, everything was delivered professionally, and we were really happy with the work.
Highly recommended!”
MushfiqCEO · Masterpiece By Number
“Working with Kayhan and the Kaysun team has been an amazing experience. They're professional, super responsive, flexible, and genuinely care about the work they do.
What really stood out was how they approached our backend marketing. We had a lot of ideas going into the project, and they helped us make sense of everything, from our email flows and customer journeys to building a better system for customer retention.
As we figured out what our business actually needed, they were always open to feedback and quick to make changes. That's something I really appreciated.
I absolutely loved working with them and would hire them again in a heartbeat. It's rare to find people who are this talented, easy to work with, and genuinely invested in your success.
Highly recommend Kaysun!”
NapuaFounder & CEO · Napua
“We had a really great experience working with Kayhan and the Kaysun team. They helped us improve pretty much everything on the email marketing side, from setting up our automations and creating better emails to fixing our deliverability and making sure our emails were actually reaching our customers' inboxes.
What I really appreciated was that they weren't just focused on sending emails and driving sales. They actually cared about how we communicated with our customers and helped us build a stronger relationship with them through more thoughtful, personalized emails.
The whole process was smooth, communication was great, and they were always open to our feedback and ideas.
We're really happy with the work they did for Ten Little and would definitely recommend them!”
FatmaFounder · Ten Little
“One thing we really loved about working with Kayhan and the Kaysun team was how they approached our email content.
We didn't want to just keep sending promotional emails to our customers. We wanted to actually educate them, help them understand their skincare better, and give them useful information they could take away from every email.
The team did a great job with that. They helped us create educational content that felt natural, easy to understand, and genuinely helpful to our subscribers.
What I appreciated most was that they understood what we were trying to achieve. It wasn't just about selling more products. It was about building trust, keeping our customers engaged, and creating a better relationship with them over time.
Really happy with the work they did and the whole experience of working together!”

Why Kaysun
We take over your whole backend marketing.
We start from your data and your customers, we fix the foundation first, and then we grow based on what the numbers tell us.
And it's not just your numbers. We bring 5+ years of data and experience from 30+ brands. So we already know what works and what doesn't. We don't waste your time or your money testing things we've already seen fail.
What we don't do
✕We don't just sit inside Klaviyo making emails.
✕We don't blast discounts at your whole list and burn your margins.
✕We don't write a campaign with AI and send it to everyone.
✕We don't use templates. Every brand gets a system built around its own data and customers.
✕We don't charge you more for 5 or 10 extra emails.
✕And we don't lock you into a contract.

No pressure. No hard sell. Worst case, you walk away knowing exactly what to fix.
- I go through your Klaviyo and Shopify data with you
- I show you where you're losing money: deliverability, flow logic, the gaps
- If it makes sense to work together, we talk about the goal. If not, you still leave with a clear plan.
How we work
What happens after we start?
Here's exactly how it goes, step by step.
Before we start
The free audit
We go through your account and show you exactly where you're leaking money, what needs to be fixed and what needs to get done. Then we set a goal together and start working on it.
Day 1
Kickoff call
On our first call, we show you exactly what we're going to do. The strategy and the plan, day by day and week by week. So you know what's going to change and when it's going to get done. You meet our team, and we meet yours.
A shared Slack channel, with replies in under an hour
If something urgent comes up, we want to know about it, and you'll get your answer fast.
Week 1
Setting up the foundation
Inbox placement
We check where your emails are landing and fix whatever is pushing them into spam or the promotions tab, so as many of your contacts as possible see them in their primary inbox.
List cleaning
You stop paying for dead profiles. And you stop sending to people who aren't interested or who are a spam risk.
Sign-up forms
You're paying a lot for ads to bring people to your site, so we make sure that traffic actually sticks around. We build new forms for your brand and start testing them right away to grow your list.
Data
We go past Klaviyo and dig into your Shopify numbers: your repeat purchase rate, your cohorts and your LTV. That shows us your true customer lifetime value, and we build your customer journeys around it.
Customer research
Before we write a single email, we get to know your customers. We survey your list, your buyers and your VIPs. We read your reviews, your competitors' emails and their customer reviews. And we go deep on Reddit to find out what your customers are really struggling with. Once we know that, we know what to send, when to send it, and how to talk to them.
Week 2
We start building the machine
Segments
Built around your customers' interests and behavior, not just whether they opened your last email.
Your main flows
Built around your customers and your data, not a copy-paste template.
WelcomeTurns new subscribers into first-time buyers.
Abandoned cartBrings back people who left something in their cart, by answering whatever stopped them, not just by throwing discounts at them.
Abandoned checkoutFollows up with people who started checking out but didn't finish.
Post-purchaseFirst-time buyers, repeat buyers and VIPs each get their own journey, with the right next step: a bundle, an upgrade or a subscription.
Your first campaigns
From a campaign calendar planned around your launches, restocks and big sale events, so every send has a reason behind it. Not just a random email because it felt like a good day to send one.
Copy and design
Written by a native copywriter and designed by an experienced graphic designer, in your brand voice.
Weeks 3–4
You always know where things stand
Reports
Every week and every month. What we did, what worked, what didn't, what we're doing next, what the goal is and how we're going to get there.
Strategy and report calls
You can call us anytime. Most brands we work with do a one-hour call each week to review the emails, check the data and go through the reports. That's entirely up to you.
Month 2
Building out and testing
The rest of your flows
Once the core is running, we build out the rest of your 30+ email and SMS flows. Every one of them knows when to fire and when to step back.
Browse abandonmentFollows up with people who looked at a product but didn't add it to their cart.
Site abandonmentReaches people who visited your site and left without looking at anything.
ReplenishmentReminds customers to reorder right before they run out.
Cross-sell and upsellThe right next product, not a random one.
Reviews and UGCTurns happy customers into reviews and content you can use.
SubscriptionsWe take care of your subscribers from the day they sign up, through the day they think about leaving, to the day we bring them back.
WinbackBrings lapsed customers back before they're gone for good.
Back in stockLets people know the moment the product they wanted is back.
VIP and loyaltyTreats your best customers like your best customers, with early access and perks.
SunsetLets inactive subscribers go before they hurt your deliverability.
Offer testing
So you're not giving away margin you don't need to. We test different offers to find the one that works best for your audience.
Month 3
Everything works together
By month three, the full system is live. Your flows, campaigns, segments and reports are all running together, and the big jump usually comes around month 3 to 4.
Month 4+
Going deeper
We split your flows by product and by customer, so different people get different journeys. And we keep testing new offers, new angles and new campaigns to keep the numbers going up.
Big sale events
Black Friday and other big sales
We don't just send "20% off, it's Black Friday." We go all in. A pop-up built for the event, landing pages, banners and offers, and your welcome and recovery flows tuned for the sale. Everything runs smoothly, and we get the most out of every visitor.
The emails
What do the emails actually look like?
They're built to sell, in your brand voice, without discount spam.
The team
Who's working on your account?
S
Strategist
Reads your data, sets the plan and decides what we test next.
AM
Account manager
Your go-to person. Keeps everything on track and on time.
C
Native copywriter
Writes every email and SMS so it sounds like your brand.
D
Designer
Designs every email so it looks as good as your product.
And then there's me. I stay involved in every account.
Pricing
Two ways to work with us
Same team, same work, same full system. The only difference is how you pay.
Option 1
Fixed
A fixed monthly retainer.
Option 2
Partnership
A lower monthly fee, plus a share of the extra revenue we bring in above where you are today. We set your baseline in the free audit, and we put a cap on sends, so we're never just blasting your list to hit a number. If you grow, we grow.
And with both
No contracts.You can cancel anytime.
We agree on a goal before we start.Usually that's email and SMS bringing in 20–40% of your total revenue. Sometimes it's engagement, deliverability or inbox placement. It depends on what you choose.
Our guarantee.If we don't hit it, you get your money back, or we keep working until we do. Easy.
FAQ
Questions I get a lot
Is the audit really free?
Yes. We go through your account and show you exactly what needs fixing, what needs optimizing and what needs rebuilding. Even if you don't work with us, hand it to your in-house team and let them run with it. It's free, and we won't charge you a thing for it.
Do I need to give you Klaviyo access?
For a deeper audit, access to Klaviyo and Shopify gives us more to work with. You can also start with screenshots or exports if you prefer.
How fast will I see results?
Faster than you think. In the first week, the new sign-up forms go live, so you'll see it in your list growth straight away. Then the welcome series starts turning that new traffic into buyers. Deliverability fixes show up in the first few weeks, revenue starts moving in the first month, and the big jump usually comes around month 3 to 4, once all the flows are working together.
I'm a subscription brand. Do you get that?
That's our main focus. Churn, skips, failed payments, cancellations, winbacks. Subscription retention is its own game, and it's the one we know best.
Will more emails annoy my customers?
Not if they're the right emails. Customers get annoyed when they get the same message three times in one day, or offers for products they don't care about. That usually happens because flows and campaigns overlap and nobody's controlling who gets what. We fix that logic, so each person only gets the emails that make sense for them. Most of the time, that means fewer emails, not more.
We already have flows set up. Do you start from scratch?
No. We audit everything first. Whatever's working, we keep, and we keep improving it based on the data. Whatever's broken or overlapping, we fix.
We already have someone doing email. Can you still help?
Yes. We can take it over completely or work alongside them.
What do I need to do?
Not much. Give us access to your Shopify and Klaviyo, plus your SMS and subscription apps if you use them, and approve the emails. We handle the rest.
