02Fix the leaksThe flows costing you most get rebuilt first.
03TestEvery rebuilt flow gets A/B tested.~4 A/B tests per client, every month

from our Loop accounts

the #1 reason subscribers cancel isn’t price.

Across the subscription brands we run on Loop, about 23% of cancel attempts in the last 90 days were people with too much product left. So we answer it with skip and slower deliveries before any discount.

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.

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.

Sebastian Agace, FounderClient

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.

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.

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

Who runs it

meet the founder.

I started Email Kong 5 years ago and I still review every free audit myself. Since then we've run Klaviyo for 140+ DTC brands, with $59M+ in revenue attributed to it.

faqs.

Some questions we get often.

What does Email Kong actually do?

We grow repeat revenue for Shopify brands. We run your Klaviyo email and SMS, plus your Loop subscriptions if you sell them, so more first-time buyers come back and you lean less on paid ads.

Are you just an email agency?

Email is the biggest part of what we do, and we also run SMS, WhatsApp, subscriptions on Loop, sign-up forms and the data set-up behind all of it.

What makes Email Kong different from other email agencies?

Every plan is built from your own numbers, margins and customers, and we report revenue with the dates so you can check it. All the work is done by our own team in-house.

Who will I actually work with?

A flows manager and a campaign manager on your account, with copy and design done by our team. Bogdan, our founder, reviews every audit and has a call with you every quarter.

Do you only work with Klaviyo?

For email and SMS, yes. We're a Klaviyo Master Platinum Partner and build everything natively, and if you're on another platform we'll move you over first. For subscriptions we work on Loop.

How do I know if I'm a good fit?

You sell on Shopify and you care about customers coming back. Most of our clients do over $2M a year, and we take smaller brands too.

Can you just audit what I have first?

Yes. The free audit shows where your account is leaking and what we'd fix first, and you're welcome to take the plan and run with it yourself.

How much does it cost?

Retainers start from $5,000 a month, as a fixed fee. There's a 3-month minimum, then 4 weeks' notice, and we send your exact quote after the free audit.
