Klaviyo Master
Platinum Partner Agency
.

Email Kong has been awarded Klaviyo Master Platinum Partner status. Klaviyo reserves that tier for the top 2.5% of agencies worldwide and audits client accounts before renewing it, so the status tracks real performance year on year. Our accounts have generated $58.2M in attributed revenue through the platform, which is the number Klaviyo themselves verified when awarding the partnership.

That partnership gives your brand something most Klaviyo accounts never get. When we spot a technical issue or need platform support, we go straight to Klaviyo's engineering team rather than logging a ticket. New features and beta tools reach us before wider rollout, so your account gains an advantage while competitors wait for the update.

Klaviyo services across the full customer lifecycle.

At Email Kong, flow automation starts with deep architecture: your customer behavior, your tech stack, your products, and how your data flows across tools like Shopify, Klaviyo, Loop, Wonderment, Recharge, and beyond.

acquisition & onboarding

Subscribers pay attention for a short window after signing up. Miss that window and conversion rates collapse. Our welcome series engages  first-time buyers through sequenced email and SMS touchpoints, while compliant opt-in systems protect your sender reputation from day one.

  • Welcome series setup across email and SMS
  • First-purchase conversion flows
  • Popup A/B testing and optimisation for list growth
  • Compliant opt-in management and subscriber segmentation
  • Early education sequences that build product value before asking for the sale

conversion

Dropped checkouts and abandoned carts aren't lost customers. They're warm buyers who hesitated or needed one more reason to commit. These Klaviyo flows exist to close that gap. Each flow responds to a specific behaviour with matched urgency and messaging designed to secure the purchase before the buyer moves on.

  • Abandoned cart flows with dynamic product blocks
  • Abandoned checkout recovery sequences
  • Browse abandonment with personalised product recommendations
  • Server-side event tracking through Klaviyo or Shopify integrations
  • Price drop and back-in-stock alerts triggered by real browsing data

retention

Your most profitable customers already exist inside your database. The challenge is giving them a reason to come back on a schedule that matches their buying behaviour. That's what retention flows do inside Klaviyo, they create purchasing cycles that provide you with regular and dependable revenue.

  • Post-purchase email flow sequences
  • Replenishment and reorder reminders
  • Cross-sell and upsell automation
  • VIP and loyalty programme flows
  • Customer data enrichment and profile property collection
  • Subscription flow strategy for recurring revenue

reactivation

Customers go quiet for different reasons, and the recovery approach should reflect that. Winback flows target lapsed buyers with messaging timed to their last purchase date rather than a blanket 90-day rule. The aim is to re-engage by keeping your brand at the top of their inbox and top of their mind.

  • Winback campaigns targeting customers past their expected repurchase window
  • Churn prevention flows for at-risk segments identified through predictive analytics
  • Back-in-stock notifications for sold-out product demand recovery
  • Sunset flows that clean unengaged contacts and protect deliverability

your first 8-weeks with Email Kong.

Below is what the first  8-weeks look like for Email Kong’s new clients. It maps the path from account setup to building your money-printing retention system. The whole process is based on our in-house framework which we call the 4-Engine LTV Multiplier System.

WEEK 1

foundation

Customer and data audit paired with core segment mapping across your full lifecycle. Design templates get refined while content angle testing begins. Top-priority flow builds kick off in parallel.

WEEK 2

first wins

Welcome and retargeting flows go live first. Your campaign calendar locks in alongside promos and brand content. Segmentation sharpens based on early engagement signals, and benchmark KPIs are set for revenue and repeat rate.

WEEK 4

full activation

High-frequency campaigns launch in coordination with active flows. Deliverability and list health optimisation runs in full swing, with performance adjustments driven by real data rather than assumptions.

WEEK 6

revenue scaling

Seasonal promos and personalisation scale across all active flows. A/B testing runs at volume across customer segments that have already shown they convert. Winback and back-in-stock segments get built out during this phase.

WEEK 8

retention engine

The complete flow ecosystem is in place, including post-purchase sequences and churn prevention logic. AOV and repeat rate climb through tailored flow triggers. Early repeat-purchase lift shows up in Klaviyo's reporting dashboard, with deliverability monitoring running continuously underneath.

Head of Strategy

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.

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 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.

Repeat Orders

Klaviyo
strategies built
for your industry.

A pet food subscription runs on a completely different reorder cycle than a fashion brand dropping seasonal collections. Flow timing, campaign calendars and even template design change depending on the vertical. We account for that and have specialist workflows for each industry sector, which is something most Klaviyo agencies skip in favour of a one-size-fits-all setup.

health and beauty

Replenishment timing is crucial for getting that second purchase over the line. We map average product consumption to trigger reorder flows before customers run out, and cross-sell complementary items based on your brand’s purchase data history.

supplements

A missed refill breaks the habit. Once that gap opens, supplement buyers rarely come back 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

Seasonal launches anchor the Klaviyo campaign calendar. We build flows around new collection drops, pre-order windows, and size-based restocking alerts.

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.

Green circular icon with white layered squares representing strategy concept.

pet supplies and food

Pet owners buy on cycles you can almost set a clock to, and they respond well to content that feels personal. We target these customers with replenishment orders tailored to their pet. And send loyalty triggers that reward the customers who keep coming back.

home and garden

Higher AOV and longer gaps between purchases call for different flow logic. Our campaign timing aligns with real seasonal buying patterns rather than generic 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.

food and drink

Food and drink customers are known for their repeat-purchase frequency. Our custom flows for this industry are designed to nudge lapsed subscribers before they churn.

faqs.

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.
