What Australian Brands Need From Klaviyo
Klaviyo's defaults, its templates and most of the advice written about it assume a US sender. Australian brands work under different rules. The Spam Act 2003 requires consent before you send, which the US CAN-SPAM Act does not. Branded SMS sender IDs now have to be registered. And the trading year peaks at EOFY in June and Boxing Day as well as Black Friday, with Christmas in summer. A program copied from a US playbook misses all three.
If you sell interstate or overseas, the Klaviyo account is the retention engine for every market you ship to, and that job rewards specialist depth more than a local office. The work is detailed: segment logic, flow timing, copy review, A/B test setup, deliverability monitoring. None of it needs a shared building. It needs someone in Klaviyo every day, which is why weekly video calls and a shared Slack channel beat a monthly meeting across a table.
/ Why us
Why Australian Brands Hire Email Optimize
Australian HQ, Australian hours. We are headquartered in Adelaide and work in ACST, or ACDT in summer, which keeps us within half an hour of Sydney, Melbourne and Brisbane all year. Calls and Slack sit inside your business day. For Adelaide clients, kickoff and quarterly reviews often happen in person.
Specialists, not a full-service shop. We do email and SMS for ecommerce brands, on Klaviyo and Omnisend, and nothing else: no web design, no paid ads. Every account runs through the five-layer DORTA diagnostic in order, starting with deliverability, because a better flow sent to the spam folder earns nothing.
Results you can check. Better Body Co. moved email and SMS from around 10% to 20-25% of revenue. Popl went from under 20% to 50-60% over 21 months. Relaxium added +$3M in incremental annual revenue. Our partner listing is in Klaviyo's directory at connect.klaviyo.com.
Published prices, no lock-ins. Published ranges are in USD. The audit is free. Fixed-scope projects, such as a flow rebuild, a migration or a deliverability fix, run $3-15K USD for a single fee. Full management retainers are typically $3-12K USD a month, month-to-month with 30 days' notice. The detail is on our pricing page.
Australian rules
The Spam Act and SMS Sender IDs: What Your Klaviyo Account Must Get Right
Marketing email and SMS sent to Australians are commercial electronic messages under the Spam Act 2003, enforced by the ACMA. The ACMA sums up compliance in three rules: get consent, identify yourself, and make it easy to unsubscribe. Since 1 July 2026 there is a fourth for SMS: register your sender ID. Here is what each one means inside a Klaviyo account. It is a summary, not legal advice.
01
Consent
Express consent, such as a ticked box or a completed sign-up form, is the ACMA's best practice, and it is up to you to prove who consented, when and how. Inferred consent is narrow: the ACMA says it does not cover sending messages after someone has just bought something from you. In Klaviyo, that means a marketing opt-in at checkout and on every form, not a list built from order history.
02
Identify yourself
Every message has to identify your business accurately, by its legal name or your name and ABN, with contact details that stay correct for at least 30 days after you send. In Klaviyo that lives in the sender details and footer of every template, including flows nobody has opened in a year.
03
Unsubscribe
Every commercial message needs a clear unsubscribe that is honoured within 5 working days, keeps working for at least 30 days after sending, costs nothing and does not ask for a login or extra personal information.
04
SMS sender IDs
Since 1 July 2026, texts sent under a branded sender ID (your business name instead of a number) need a registered ID, or they display as "Unverified". You register through the telco or message provider that sends your texts, and with an ABN the ID has to match your business name, company name, trade mark or domain name. Branded sender IDs generally cannot receive replies, so "Reply STOP" will not work from one.
Sources, checked October 2026: the ACMA's Avoid sending spam guidance and SMS Sender ID Register page, and business.gov.au (8 May 2026). The detail, with penalties, is in our email marketing laws guide and SMS compliance guide.
Retail calendar
The Australian Retail Calendar Your Flows and Campaigns Run On
A US calendar builds to Black Friday and goes quiet in January. Australia has two more peaks, and the seasons are flipped: EOFY lands in winter and Christmas in summer. These are the dates we plan around, with 2026 dates from Australia Post's ecommerce calendar.
01
EOFY, June
The Australian financial year ends on 30 June, and end of financial year sales run through June. Plan the segments, offers and send cadence in May, not the week before.
02
Click Frenzy, November
Click Frenzy: The Main Event runs on 12 November 2026, about two weeks before Black Friday. It opens the holiday season, so list cleaning and warm-up sends have to be finished before it, not before Black Friday.
03
Black Friday and Cyber Monday
Black Friday falls on 27 November 2026 and Cyber Monday on 30 November. Every sender peaks in the same week, so your inbox placement depends on the sending reputation you built in October.
04
Boxing Day, 26 December
Boxing Day sales start with much of the country, your own team included, on summer leave. Schedule the campaign and check the flows before the break: cart and browse abandonment, back-in-stock and post-purchase run unattended through January.
Our email marketing calendar has the full Australian list, including Mother's Day, Father's Day and the Christmas shipping cut-offs.
Where you are
Sydney, Melbourne, Brisbane, Perth and Adelaide
Where you are changes the meeting times, not the work. The model is the same in every city: weekly video calls, a shared Slack channel and monthly reporting in revenue per recipient and flow contribution.
01
Sydney
We are 30 minutes behind Sydney all year, daylight saving included, so our working days overlap almost completely.
02
Melbourne
The same as Sydney: 30 minutes apart all year, with calls anywhere in your business day.
03
Brisbane and the Gold Coast
Queensland skips daylight saving, so we are 30 minutes behind Brisbane from April to October and 30 minutes ahead from October to April. Either way, a full shared day.
04
Perth
Perth runs 1.5 hours behind Adelaide, or 2.5 hours while we are on daylight saving. Your morning is our late morning or early afternoon, so most of the working day is still shared.
05
Adelaide
Our home city. Kickoff and quarterly reviews often happen in person. The day-to-day runs over Slack and weekly calls, the same as everywhere else.

How we diagnose every Klaviyo account.
Most email programs don't fail dramatically. They decay slowly. Across $250M+ in attributed revenue and 800+ brands, every decaying program fails at one of five sequential layers. DORTA names them so we can fix them in order.
L.01
Delivered
Inbox placement is the foundation. Authentication, list hygiene, engagement-based suppression.
L.02
Opened
Inbox trust is behavioural memory. Six irrelevant emails train subscribers not to open the seventh.
L.03
Read
One email, one message, one action. Most ecommerce email is too long and asks too early.
L.04
Trusted
Trust turns an occasional opener into someone who expects your emails. It compounds across every send.
L.05
Acted
Conversion is the output of every layer working together. Most "conversion problems" are actually trust or read problems.

Questions about Australia.
Q.01 Are you an Australian Klaviyo agency? +
/ Answer
Yes. Email Optimize is headquartered in Adelaide and was founded in 2017. We are an official Klaviyo partner and an official Omnisend partner, working only with ecommerce brands, with $250M+ in attributed email and SMS revenue across 800+ brands. Our listing is in Klaviyo's partner directory at connect.klaviyo.com, which is the authoritative source for current partner status.
Q.02 Do you work with brands outside Adelaide? +
/ Answer
Yes, across Australia and overseas. Day-to-day work runs over Slack and weekly video calls, which suits detailed Klaviyo work better than monthly in-person meetings. We are within half an hour of Sydney, Melbourne and Brisbane all year. For Adelaide clients, kickoff and quarterly review meetings often happen in person.
Q.03 How do you price Klaviyo work for Australian brands? +
/ Answer
The same way we price everywhere, and we publish it. Published ranges are in USD. The audit is free. Fixed-scope projects run $3-15K USD depending on scope, for a single fee. Full management retainers are typically $3-12K USD a month, month-to-month with 30 days' notice. We price by project and retainer, never by the hour. Specific scope and price come with the free audit, so the recommendation matches the actual revenue opportunity.
Q.04 Does the Spam Act apply to Klaviyo email and SMS? +
/ Answer
Yes. Marketing email and SMS sent to Australians are commercial electronic messages under the Spam Act 2003, which the ACMA enforces. You need consent, accurate sender identification and an unsubscribe that is honoured within 5 working days. The ACMA says inferred consent does not cover sending marketing just because someone bought from you, so collect an explicit opt-in at checkout and on every sign-up form.
Q.05 Do I need to register my SMS sender ID? +
/ Answer
If you text from your brand name rather than a phone number, yes. Since 1 July 2026, texts from unregistered branded sender IDs display as "Unverified". Registration goes through the telco or message provider that sends your texts, and if you have an ABN the ID has to match your business name, company name, trade mark or domain name.
Q.06 What is the DORTA method? +
/ Answer
DORTA is our proprietary diagnostic framework: Delivered, Opened, Read, Trusted, Acted. Every Klaviyo program that's underperforming fails at one of these five layers, in order. Fixing layer 5 (conversion) when layer 1 (deliverability) is broken just paints over the real problem. We diagnose all five before recommending any work.
Q.07 How do you measure success? +
/ Answer
We measure in revenue per recipient (RPR), flow contribution as a percentage of total email revenue, and incremental revenue (validated via holdout testing where applicable). We don't measure in open rates: since iOS 15, opens are a corrupted signal.
Q.08 What's included in your free Klaviyo audit? +
/ Answer
A revenue gap analysis, flow audit covering all 10+ recommended automations, deliverability check (authentication, sender reputation, list health), segmentation depth review, and a 90-day roadmap with sequenced priorities. Response within 24 hours of access.
