Ecommerce email marketing services.
Six services, one team. Built on Klaviyo, or Omnisend where it fits better: two platforms known deeply, not ten known shallowly. Each piece feeds the next, so you end up with a revenue engine that compounds, not a stack of disconnected tactics.
Most retainers start with the flows, then take over the weekly sends. That second half is our outsourced email marketing service: you approve the calendar and read the report, we plan, write, design, build and send. The emails themselves come from our email design and copywriting service, judged on clicks, not looks.
Flow Automation
10+ revenue flows: welcome, abandoned cart, browse abandonment, post-purchase, replenishment and win-back.
Outsourced Email Marketing
Weekly segmented campaign sends that earn revenue without burning your list or your sender reputation.
Klaviyo Setup & Migration
New Klaviyo builds for Shopify and other platforms, and done-for-you migrations from Mailchimp, Omnisend or any major ESP.
Deliverability
Inbox placement audits, authentication (DKIM, SPF, DMARC), reputation recovery and warm-up.
List Growth
Popups, lead magnets and post-purchase capture that grow the list with buyers, not freebie hunters.
SMS Marketing
Compliant SMS opt-in, and email and SMS flows that take turns inside Klaviyo instead of stacking.
How we work vs. how creative agencies work
A heavily designed email can take around 30 hours to produce and gets called "elevated content." In our experience, a conversion-engineered email takes about 4 hours and gets the click. The difference shows up in your revenue, not your inbox.
Other agencies
They decorate.
- The goal A beautiful email worth showcasing in their portfolio
- The metric Open rate, "engagement," brand consistency
- The email Image-heavy, scrollable, multi-section, designer-approved typography
- A/B testing Subject lines, occasionally
- The reporting Monthly engagement deck with vanity metrics
- Hours per email Around 30 hours of design work
- What you get A pretty inbox
Email Optimize
We engineer.
- The goal The click and the sale. Pretty isn't a goal.
- The metric Revenue per recipient, attributed orders, flow contribution %
- The email One message, one CTA, mostly text, built for inbox placement
- A/B testing Subject + send time + flow architecture + segment + offer
- The reporting Live revenue dashboard. Klaviyo access. Monthly written read-out.
- Hours per email About 4 hours of engineering, not 30 of decoration
- What you get Email + SMS growing as a share of revenue (Popl: under 20% to 50-60%)
If you've been told email is supposed to look like a landing page, you've been sold a billable hour, not a revenue strategy.
Why pretty emails lose: read the manifestoWhy ecommerce email marketing is its own discipline.
Ecommerce email is a different sport. A generalist agency optimises for open rates and weekly newsletters. An ecommerce email marketing agency optimises for revenue per recipient, predicted customer lifetime value, replenishment timing, and the gap between an abandoned cart sequence built on real checkout behaviour and a single reminder. Klaviyo's 2026 benchmarks, drawn from more than 183,000 customers, show automated flows generate nearly 41% of email revenue from just 5.3% of sends (source). That is where ecommerce email is won or lost, and it is exactly what a newsletter agency ignores.
The platform you build on, the data you feed it and the flow logic you wire up are not interchangeable with B2B nurture or creator newsletters. They are their own discipline. We picked it and went deep.
Klaviyo-first, by design
Klaviyo is the ecommerce email and SMS standard, so most of our programs run on it: its predictive analytics, its product-event triggers, its native Shopify integration. Where Klaviyo is the wrong fit, we build on Omnisend instead.
Ecommerce only, by choice
Every flow, segment and campaign we build is calibrated to product-purchase behaviour. We don't do lead generation, B2B nurture or creator newsletters. The narrowness is the value.
Revenue-first reporting
We report revenue per recipient, attributed orders and flow contribution. Open rate is a leading indicator, not the scoreboard.
Built to compound
Email isn't a one-time project. Every retainer includes monthly flow iteration, campaign optimisation and segment refinement. The asset compounds.

Your Klaviyo subscription is billed by Klaviyo, priced on active profiles, and sits outside our fee. Some agencies publish lower entry points for production-only work; others start higher for enterprise programs. Whoever you hire, get the scope in writing: campaigns a month, flows built or optimised, whether SMS is in, and how results are reported.

An Australian email marketing agency, Adelaide HQ.
Australia is home. Email Optimize is headquartered in Adelaide, so Australian brands get local business hours, calendars built for the Australian retail year and Spam Act 2003 compliance by default. The same team runs Klaviyo programs for US and UK ecommerce brands, on their hours. Same engineering discipline everywhere; the calendar, the compliance rules and the business hours change by market. Running Klaviyo in Australia? See our Klaviyo agency for Australian brands.
Australia, our home market
Adelaide HQ and Australian business hours. Campaign calendars built around EOFY and Boxing Day rather than borrowed from BFCM. Spam Act 2003 compliant by default, and flow logic tuned to your list size and order values, not a US template.
Klaviyo agencies in Australia, ranked → USEcommerce brands in the United States
US client work runs in US business hours. Our US receipts are named: Relaxium (INC 5000), where Pete served 22+ months as Head of Retention Marketing, and Popl (Y Combinator backed), where email and SMS went from under 20% to 50-60% of revenue. CAN-SPAM and CCPA handled in setup, BFCM planned from September.
Klaviyo agency for US brands → UKEcommerce brands in the United Kingdom
We work with UK brands from Adelaide: calls and reviews in the UK morning, drafts and reports delivered overnight for your next morning. UK GDPR and PECR consent capture checked at every sign-up point. If you need live cover through the UK afternoon, we will tell you honestly that a London agency is simpler.
Klaviyo agencies in the UK, ranked →Shopify email marketing on Klaviyo.
On Shopify, Klaviyo is the default for a reason. Its native Shopify integration syncs orders, checkouts, customer profiles and the product catalog, and with onsite tracking installed, product views. That data is what flows and segments run on.
Connecting it is one click. Connecting it properly is where brands quietly lose value. We set Shopify stores up on Klaviyo, or on Omnisend where it fits better, and we are an official partner of both. Leaving Shopify Email, Mailchimp, ActiveCampaign, MailerLite or HubSpot? We run done-for-you Klaviyo migrations with deliverability protected through the cutover.
Start with a Klaviyo setup or a free Klaviyo audit, read about our Klaviyo agency work, or meet the Klaviyo experts on the team. Running Omnisend? See our Omnisend agency page. The integration detail is in our guide to connecting Klaviyo to Shopify, and our ranking of the best Shopify email marketing agencies shows how we compare.
What we check on every Shopify store
Onsite tracking firing
Without it you get orders but no product views, which means no browse abandonment flow and weaker segments.
Order history backfilled
Profiles carry real purchase history before the first flow goes live, so segments work on day one.
Cart flow on the right event
Started Checkout, in most stores, so the flow reaches people who were really in checkout.
Catalog synced, domain authenticated
Dynamic product blocks that show the actual product, sent from a branded domain that passes DMARC.
How to choose an ecommerce email marketing agency.
Every email marketing agency says it is strategic and data-driven. None of that is checkable. Ask for receipts instead: revenue per recipient before and after for a client like you, three named clients in your category, the name of the person who will run your account and how many other accounts they carry, and what they fix in the first 30 days. If the first answer is a template redesign, keep looking.
Our receipts: $250M+ in attributed email and SMS revenue across 800+ ecommerce brands since 2017, and named case studies with Relaxium, Popl and Better Body Co. We are not the right email marketing agency for everyone, so we ranked twelve of them, ourselves included, with the brand profile each one fits best.

Ecommerce email marketing agency FAQs.
Q.01 What does an ecommerce email marketing agency actually do? +
/ Answer
An ecommerce email marketing agency builds and runs the email and SMS systems that earn a share of your store's revenue: flow automation (welcome, abandoned cart, post-purchase, win-back), weekly campaign sends, list growth, deliverability and reporting. How big that share gets depends on the brand. Better Body Co. moved email from 10% to 20-25% of revenue after a 3-month consulting engagement with us; Popl moved email and SMS from under 20% to 50-60% over 21 months.
Q.02 Why only ecommerce, instead of every industry? +
/ Answer
Ecommerce email is a different job from B2B or content email. Triggered flows around purchase behaviour, predicted customer lifetime value, replenishment timing and product-level segmentation are the levers that move ecommerce revenue, and they take deep platform fluency and category judgement. Generalists optimise for opens. We optimise for revenue per recipient.
Q.03 Which platform do you build on? +
/ Answer
Klaviyo for most brands, and Omnisend where it is the better fit for the store’s size, team or budget. We are an official partner of both. Knowing two platforms deeply produces better outcomes than knowing ten shallowly. For regulated categories, we check your catalogue against both platforms’ policies and get the platform’s sign-off in writing before we build: Klaviyo prohibits pharmaceutical products on every channel, and Omnisend’s policy prohibits prescription medications, including drugs sold for research purposes. If you are on Mailchimp, ActiveCampaign or another ESP, we run a done-for-you migration as part of the engagement.
Q.04 How quickly will I see revenue results? +
/ Answer
Fixes come in order: deliverability first, then the flows that carry the most revenue, then campaigns. A repaired flow starts earning as soon as it is live, because it runs on traffic you already have. The compounding effect takes 90 to 180 days, as flows mature, segments are refined and campaign cadence settles. You see revenue per recipient in the monthly report from month one, so you can judge the direction yourself.
Q.05 What size brands do you work with? +
/ Answer
We work with ecommerce brands typically doing $500K to $50M+ in annual revenue. Below that, the value of a senior team is harder to justify; above $50M, the work usually warrants a dedicated in-house retention lead with us as a strategic partner rather than a full-service agency.
Q.06 How is pricing structured? +
/ Answer
Projects for defined deliverables, then a monthly retainer for ongoing work. The audit is free. Setups, migrations, flow rebuilds and deliverability fixes are fixed-scope projects with a single fee agreed upfront. Ongoing flow optimisation and campaign management is a monthly retainer, month-to-month with 30-day notice. We do not bill by the hour. The free audit comes back with a specific scope and price within 24 hours.
Q.07 How much does an ecommerce email marketing agency cost? +
/ Answer
Ours: the audit is free, one-off projects such as setups, migrations and flow rebuilds run $3-15K USD depending on scope, and retainers typically run $3-12K USD a month for ecommerce brands, depending on flows, campaign volume, SMS and list size. Published ranges are in USD. Some agencies publish lower entry points for production-only work; others start higher for enterprise programs. Budget separately for your Klaviyo subscription, which Klaviyo prices on active profiles. The only number that matters is incremental email and SMS revenue against the fee.
Pricing and engagement types →Email marketing agency pricing, the market →
Q.08 Do you work with ecommerce brands in the US, UK and Australia? +
/ Answer
Yes. We are headquartered in Adelaide and work with Australian brands in local business hours, with US brands in US business hours, and with UK brands through the UK morning overlap plus overnight delivery. Compliance defaults are set per market: the Spam Act 2003 in Australia, CAN-SPAM and state privacy laws like CCPA in the US, and UK GDPR and PECR in the UK.
Q.09 Is email marketing still worth it in 2026? +
/ Answer
For ecommerce, yes. Email and SMS reach customers you already paid to acquire, without paying again for every click. Klaviyo’s 2026 benchmarks, drawn from more than 183,000 customers, show automated flows generate nearly 41% of email revenue from just 5.3% of sends. What has stopped working is lazy email. Since February 2024 Gmail and Yahoo have required bulk senders to authenticate, offer one-click unsubscribe and keep spam complaints low, so full-list blasts to people who never open get filtered. Email built on flows, segments and clean sending is worth more than it was. A weekly newsletter to everyone is worth less.
Klaviyo 2026 email benchmarks →Gmail and Yahoo sender rules →
Q.10 What is the 80/20 rule in email marketing? +
/ Answer
It is the Pareto principle, named after the economist Vilfredo Pareto, applied to email: a minority of causes tends to produce most of the results. In an ecommerce account that usually means a minority of subscribers, your engaged buyers and repeat customers, produce most of the email revenue, so you segment and protect them before you optimise sends to the whole list. Some marketers use the same label for content mix: mostly useful or entertaining emails, with a smaller share of direct selling. Either way, 80/20 is a rule of thumb, not a measured ratio. Pull revenue by customer from your own account to see your real split.
