HOW THIS IS FUNDED

Better Agencies is free for business owners. We are paid a referral fee by an agency only if you choose to be introduced and you go on to work with them, and that fee is the same regardless of which agency you pick — so it cannot change the order of this list. Nobody on this page has paid for placement, and no agency sees your enquiry unless you ask us to make an introduction.

Information on this page is compiled from public sources and may not be fully accurate or up to date — agency offerings, pricing and availability change. Always confirm details directly with an agency before making a decision.

What makes a good email marketing agency

Most agency roundups rank on revenue, headcount, or how much the agency paid to appear. None of that tells you whether the work will suit your business. A good email marketing agency is one whose shape matches your problem — a small local specialist and a large multi-office team can both be the right pick, and choosing the wrong one costs you a year.

How we pick

01
Real presence, not a placement fee

We start from who genuinely ranks and gets reviewed for this work in this market, not who paid to be on a list.

02
What their own site actually says

We read the services, specialisms and case studies each agency publishes themselves, rather than taking a pitch at face value.

03
Fit over size

A nine-person specialist and a forty-person team can both be the right answer. We flag who each agency actually suits.

04
What is missing

No pricing on the site, no case studies, no clear specialism — we say so, rather than papering over the gaps.

What you should consider

01
Your stage, not your size

A business with nothing running yet needs foundations shipped. A business already getting results needs someone who can find the next percentage point. These are different agencies.

02
Local vs national fit

If your customers are in one city, a local specialist with local runs on the board usually beats a national generalist. If you sell everywhere, the reverse is often true.

03
How much of your own time this needs

Some engagements need your input weekly, others run mostly hands-off. Ask what they need from your side before you sign.

04
What happens after month twelve

Ask what the account looks like a year in and who owns the assets. If the answer is vague, that is the answer.

Best Email Marketing agencies in Australia

Ranked by who they suit, not who pays. Sourced from real Google Business Profile standing for "email marketing agency australia", verified against each agency's own site.

Email marketing is a thin, specialist category in Australia — genuine dedicated shops mostly compete on Klaviyo/lifecycle expertise for eCommerce rather than local search, so this list favours verified national Klaviyo partners over a single city's local pack.
