Bogdan really knows what he's doing
Bogdan really knows what he's doing. He has a lot of knowledge and experience in this field and we truly appreciate not only his email marketing expertise but overall ideas to grow the business. Would recommend!
Absolutely the best
Absolutely the best, we tried others before and no one has been able to compare. Bogdan is the man, and you can tell he truly cares about the work relationship and brand growth, man of high integrity. Will continue working with him in the future with next brands to come. If you want the best, Email Kong will get it done. Have already referred to multiple friends at scale.

We're so glad we've found Email Kong! After working with many agencies, I can confidently say that they are the best out there! Their strategic approach helped streamline our customer journey and maximize our email list ROI.
What can I say
What can I say, Bogdan is the MANN. Alongside his team of killers, i could not ask for a better email marketing team for my business
Bogdan and his team are by far the best…
Bogdan and his team are by far the best email agency I've worked with. What sets him apart isn't just the quality of the emails, it's that he genuinely cares about your brand succeeding. He's gone well beyond just managing flows and campaigns, actively guiding me on growth strategy and what moves to make as I scale and expand the brand.
The email quality is consistently excellent and email has become a reliable percentage of our monthly revenue every single month. On top of that, my previous email agency had completely destroyed my domain deliverability, and Bogdan came in and turned that around significantly, something I wasn't sure was even fixable when we started working together.
If you're serious about email as a revenue channel and want someone who treats your brand like it's their own, look no further. Couldn't recommend him more highly.
I've been working directly with Bogdan…
I've been working directly with Bogdan since end of 2023. The thing I've loved the most is having the privilege to work with him directly — not some account manager who's juggling 30 other brands and doesn't know or care about your business. Admittedly that's probably a privilege that comes with scale, but it makes a massive difference when you need to move quickly and want someone who genuinely gets what you're trying to do. Bogdan's team of designers, strategists and copywriters are fantastic too, we wouldn't work with anyone other than EmailKong. Highly recommended.

Email Kong have been amazing since getting them on board. They have managed to completely change our email marketing making it a key revenue channel for our business. Their ongoing work is key to our business.
Actually cares about your brand (rare in ecom)
I’ll be real—if you’ve been in ecom for any amount of time, you know how many people in this space overpromise, underdeliver, or just straight up don’t care once they’re paid.
Working with Bogdan has been the complete opposite of that.
He helped us scale and maintain around 30%+ of our total revenue coming from email through Klaviyo, which is not easy to do consistently. It wasn’t just about setting things up and disappearing—he stayed involved, optimized constantly, and actually paid attention to what was working vs. what wasn’t. Has also helped our brand reputation online via reviews.
What stood out the most though is that he went beyond just “email marketing.” He was in the trenches with us. Helping think through problems, giving real advice, and honestly just being someone you can rely on when things get messy (which they always do in ecom).
He even went as far as putting his own skin in the gam of our brand, which says a lot about how much he actually believes in the brands he works with.
Also—this is underrated—but he’s connected us with solid people and helped us avoid a lot of the typical scammy nonsense you run into in this industry.
If you’re looking for someone who just sends emails, there are plenty of options.
If you want someone who actually gives a damn about your brand, your numbers, and your long-term growth, he’s one of the few.
Not perfect, but real—and that’s exactly what you want.
If you are a 7-8 figures brand looking…
If you are a 7-8 figures brand looking for the best email-marketing agency to partner with, there you go...High level team, results speak for themself.
Bogdan truly is a master of his craft
Bogdan truly is a master of his craft. Our business was already doing email marketing when we reached out to Bodgan, and it was doing okay.
After working with the Email Kong team our campaign performance has been supercharged, our email flows are generating significantly more revenue than previously and we also have a burgeoning SMS channel. Our mailing list is also growing at significantly higher levels than previously.
Having worked with a few agencies in the space, I can say that Bogdan and his team at Email Kong are by far the most proficient and I would not hesitate for a moment to recommend them to anyone else who is looking to turn Email into a major channel for their business.
The Hidden Garden
Email Kong has been an incredible resource for our Shopify store. I've been consistently impressed with their CRM knowledge and work product. They have helped elevate our email strategy significantly and we've seen a major lift in average order value.
Awesome results and fantastic team
Our pet food brand is working with Email Kong already for more than a year. We love the creativity and fast delivery of the team for our CRM as client management gets more and more important.
Stop looking for an alternative - there is no better agency!
From the moment we engaged with Email Kong, Bogdan's expertise and professionalism stood out. His understanding of our needs, brand voice, and vision has been outstanding - cementing his team as a trusted partner, not just an external agency. The designs and content they have crafted for our email campaigns & flows have exceeded our expectations every time, truly elevating our email marketing efforts. We have seen an increase across all key metrics! They've continually provided so much value to our business -- whether it be through experienced insights, providing recommendations to help us grow, flagging potential issues, or literally just taking a brand problem and going above & beyond to help fix it (which would normally be an out of scope problem, but they also know the value of the partnership). I honestly cannot recommend them enough.
It was great working with Bogden
It was great working with Bogden! He has taken us from doing $2,000 a month with our email flows to doing $6,000 a month! If you are questioning his prices or if it's worth it, just know you will recoup all of your spend within the first two months at most

Bogdan Mihalache
Head of Strategy
Bogdan leads strategy at Email Kong, helping 140+ DTC brands turn Klaviyo data into compounding retention revenue. Over 5 years in the platform, he's built the agency's audit framework, segmentation playbooks, and the predictive models that shape every account we touch. He sits on Klaviyo's Partner Advisory Council and obsesses over the numbers most agencies skip - repeat rate, cohort LTV, and the 90-day signals that separate growing brands from plateauing ones. If it can't be measured, he's not interested.

Calvin Nguyen
Campaign Manager
Calvin leads one of Email Kong's campaign pods, planning and executing monthly calendars for DTC brands sending anywhere from 16 to 32 campaigns a month. Five years into Klaviyo, he's developed a sharp instinct for what drives repeat orders - the right offer cadence, the right segment splits, and the small frequency tweaks that lift revenue without burning the list. He treats every send as a test, every calendar as a hypothesis, and every drop in repeat rate as a problem worth solving.

A pet food subscription runs on a completely different reorder cycle than a fashion brand dropping seasonal collections. We have specialist workflows for every industry sector to squeeze the most value and get the best results.
health and beauty
We set reorder triggers based on average product consumption, so a 30-daymoisturiser and a 90-day serum fire on different timelines within the same account. Cross-sell automation pulls from skin type and routine data collected at signup.
supplements
A missed refill breaks the habit. Once that gap opens, supplement buyers rarely comeback unprompted.
Our flows fire before supply runs out. Cancellation prevention sequences intercept at the subscription portal. Winback triggers activate early with targeted offers tied to the subscriber's original purchase.
fashion and apparel
Browse abandonment matters more here than in any other vertical because shoppers compare across multiple sessions before buying. We build those flows with longer attribution windows and style-led content. Restocking alerts fire on size-specific triggers alongside seasonal campaign sends timed to collection drops.
jewellery and luxury goods
Longer consideration windows. Higher price points. The automation matches that pace. Browse abandonment runs slower with education-led content rather than discount pressure, and post-purchase sequences focus on care and styling before introducing a second piece.
pet supplies and food
Pets are fussy about what they eat. This fact makes reorder cycle automations one of the most effective money spinners in this industry. We segment by pet type and breed,then set replenishment flows on actual consumption rates rather than arbitrary time gaps.
home and garden
Gaps between purchases stretch to months here. Post-purchase sequences run a slow drip of care tips and complementary suggestions. Seasonal campaigns align with real planting cycles and renovation windows rather than promotional calendars.
florals
Date-triggered automation runs this category. Birthdays, anniversaries, Valentine's Day, Mother's Day, all with reminder flows firing in advance. Subscription reactivation catches lapsing weekly and fortnightly customers before they cancel.

Some questions we get often.
What does Email Kong actually do?
We help eCommerce brands grow repeat revenue. That means building out your full retention strategy - email, SMS, WhatsApp, and more - so you can convert more customers, increase LTV, and reduce reliance on paid ads.
Are you just an email agency?
Not even close. We’re a full CRM and retention partner. Email is the foundation, but we also optimize your tech stack, fix broken data flows, scale SMS, improve tracking, and design customer journeys across every touchpoint.
What makes Email Kong different from other email agencies?
We don’t do templates or “30% email revenue” vanity metrics. Every strategy is built from scratch based on your business model, goals, margins, and customer behavior. And everything is done in-house - no juniors, no outsourcing.
Who will I actually work with?
You work directly with senior strategists who have built and scaled brands - not junior account managers. From strategy to execution, we stay hands-on.
Do you only work with Klaviyo?
Yes - we’re a Klaviyo-certified email marketing agency and build everything natively in Klaviyo. But we go way beyond it by integrating tools like Postscript, Attentive, Wonderment, Loop, Recharge, and more.
How do I know if I’m a good fit?
If you’re a DTC brand doing over $2M/year and care about retention, LTV, and owned growth - you’re in the right place. Especially if you’re tired of generic playbooks and want a partner who actually gets under the hood.
Can you just audit what I have first?
Absolutely! Our free audit reveals exactly where your setup has gaps, and what we’d do to fix it. There’s no pressure to work together right away. You’re welcome to take the insights and run with them. When you're ready to work together, we’ll be here.
