Bogdan leads strategy at Email Kong, helping 140+ DTC brands turn Klaviyo data into compounding retention revenue. After a decade 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 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.
Mia runs the CRM Flows department at Email Kong, owning the always-on revenue that funds growth for every client we work with. Ten years deep in lifecycle marketing, she's architected hundreds of welcome series, post-purchase journeys, and winback sequences across DTC verticals - from supplements to pet to fashion. Her focus is LTV: building the segmentation, splits, and message hierarchies that turn one-time buyers into repeat customers. She believes a great flow is invisible to the customer and unmissable on the P&L.
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.

email marketing
strategies built
for your industry.
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.
faqs.
Some questions we get often.
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.
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.
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.
You work directly with senior strategists who have built and scaled brands - not junior account managers. From strategy to execution, we stay hands-on.
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.
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.
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.
