Ecommerce Email & Retention Agency

YOUR EMAIL LIST
IS WORTH 3× MORE
THAN IT'S GENERATING

Most Shopify brands extract less than 15% of their email list's true potential. EcomKings rebuilds your retention channel from the ground up — more revenue, less ad spend.

The problem

You're Paying For
Customers Twice

You're spending thousands every month on Meta and Google to acquire customers — then letting them go cold. Your email list is a gold mine you've already paid for, and right now it's sitting idle.

The brands hitting 35–40% email revenue aren't luckier than you. They have a system. Automated flows that run 24/7. Campaigns that land in the inbox, not the promotions tab. A retention engine built to compound over time.

  • Abandoned cart flows that never got set up
  • Campaigns going out once a month (if that)
  • No segmentation — same email to everyone
  • List getting cold and unsubscribes creeping up
  • No clarity on what email is actually generating
What We Do

We Own Your
Retention Channel

You run your business. We run your email. Every flow, every campaign, every segment — done for you, start to finish.

Email Flows

Every automated sequence your store needs — welcome series, abandoned cart, browse abandonment, post-purchase, winback, and more. Built in Klaviyo, designed to convert.

Klaviyo

Campaign Management

Consistent, on-brand email campaigns built around your calendar — launches, promos, seasonal pushes, and evergreen sends. Copy, design, send, report. All handled.

Weekly Sends

SMS Marketing

Text message campaigns and flows with industry-leading open rates. Integrated with your email strategy so every touchpoint feels coordinated, not spammy.

Postscript / Attentive

List Segmentation

VIPs, at-risk customers, first-time buyers, big spenders — we segment your list so every email is relevant. Relevance means higher open rates, higher clicks, more revenue.

RFM Segmentation

Deliverability & List Health

Inbox placement is everything. We monitor your sender reputation, clean your list, manage suppression, and ensure your emails actually arrive — not the spam folder.

Ongoing

Reporting & Attribution

Monthly reporting that shows exactly what email generated in revenue. No vanity metrics — just clear attribution, what's working, and what we're optimizing next.

Numbers Don't Lie

Why EcomKings

We Only Do
Ecommerce

Ecommerce-only. No generalists.

We don't work with B2B SaaS, restaurants, or real estate. Every client is a Shopify or DTC brand. That focus makes us sharper than a full-service agency.

We write the copy. We design the emails.

No outsourcing copy to you or a freelancer. Our team handles everything — strategy, copy, design, build, send. You review and approve.

Month-to-month. You're not locked in.

No 6-month contracts. No exit fees. We earn your business every single month. If we're not delivering, you walk. That's how it should be.

You own everything. Always.

Your Klaviyo account, your flows, your templates. If you ever leave, you keep 100% of the work we've built. It's yours.

Real ecommerce experience — not theory.

Our team has run Shopify stores, managed ad accounts, and shipped products. We understand your business because we've lived it.

FAQ

Common Questions

We primarily build in Klaviyo — it's the industry standard for Shopify brands and the most powerful platform for segmentation and flows. We also work with Postscript and Attentive for SMS. If you're on a different platform, reach out and we'll let you know if it's a fit.
Most clients see measurable email revenue within the first 30 days — that's when core flows go live and start running. Bigger gains compound over 60–90 days as we optimize, add flows, and refine segmentation. We're transparent about timelines from day one.
No. We handle copy, design, and build entirely. You'll get a brand brief process during onboarding so we learn your voice, products, and audience — after that, we produce everything. You review and approve before anything goes live.
That's great — we'll audit what you have, keep what's working, rebuild what isn't, and fill the gaps. We don't blow up working systems. Starting from something is always better than starting from zero.
No setup fee, no minimum contract length. Every plan is month-to-month. We charge the same from month one because we move fast — typically you have flows live within the first 2–3 weeks.
Our sweet spot is Shopify brands doing $20K–$1M+ per month in revenue. Smaller stores can still benefit, but the ROI is most dramatic once you have meaningful list size and order volume to work with. The free audit will give you an honest read on whether we're the right fit.
100%. Everything we build is in your Klaviyo account under your ownership. If you ever leave, you keep every flow, every template, every segment. No holdbacks, no access revocations. It's your asset.
We cap new client intake at 5 per month to protect quality. Each brand gets proper attention — not a conveyor belt. If we're at capacity, we'll put you on a short waitlist and give you an honest timeline.
