built for direct-to-consumer brands.

Email Kong was built with a clear mission to help d2c brands scale by maximising revenue from their existing customer base. We have the specialist skills and experiences to build a  customer engagement retention system for your brand. Every flow and campaign maps to your actual customer data rather than assumptions about how shoppers should behave.


Our 4-Engine LTV Multiplier System structures this work into four connected layers. Automated flows run your lifecycle engine. Campaigns keep your brand visible between purchases. Your tech stack powers the data behind every decision. And a retention strategy ties it all into one system where churn rate drops and LTV compounds.


We’ve been awarded Master Platinum status by Klaviyo, putting us in the top 2.5% of d2c marketing agencies globally. 65% of brands we onboarded still work with us today.

dtc retention strategies built for your industry.

A health supplement brand running 30-day replenishment cycles needs fundamentally different automation logic than a homeware brand whose customers buy twice a year. We build for those differences rather than applying one playbook across every vertical.

health and beauty

Replenishment timing decides whether a customer reorders or switches brands. We map average product consumption to trigger reorder flows before customers run out and layer in post-purchase education that builds confidence in new SKUs.

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

Seasonal drops and new collection launches anchor the campaign calendar. Browse abandonment flows capture intent from window shoppers. Segmentation splits by purchase recency and category preference so messaging shifts as trends move.

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

We segment by pet characteristics and purchase frequency. Replenishment flow timing matches delivery schedules to standard consumption rates of each type of pet and breed.

home and garden

Home and garden is well known for high average order values but longer gaps between purchases. Our post-purchase sequences stretch engagement across weeks to keep your brand in their mind.

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.
