Email Marketing Benchmarks Australia 2025: What Good Looks Like for Small Business

Australian small businesses send emails that outperform the global average on every major metric: open rates, click rates, and click-to-open rates all sit higher here than anywhere else MailerLite measured across 3.6 million campaigns between December 2024 and November 2025. Yet most owners have no reliable way to know whether their own numbers are healthy or bleeding money. They either chase unrealistic targets borrowed from US benchmarks or pull back on email investment because they assume the channel stopped working.

What the data actually shows for Australian senders

The MailerLite dataset puts Australian campaigns at 47.69 percent average open rate, 2.82 percent average click rate, and 8.3 percent click-to-open rate; each figure leading the twelve regions tracked. Vision6, an Australian email platform, reports a more conservative 21.5 percent average open rate across their local client base, with healthcare leading at 26.8 percent. The gap between the two sources comes down to methodology: MailerLite measures verified sends from active accounts with at least a thousand subscribers, while Vision6 includes smaller lists and newer senders. Both datasets agree on the ranking. Australia sits at or near the top.

RockingWeb's 2025 breakdown adds texture. Open rates climb with list age and fall with send frequency. Tuesday through Thursday sends outperform Monday and Friday by two to three percentage points. Mobile opens now exceed seventy percent across every industry vertical. The median conversion rate from email traffic sits at 4.24 percent according to Porch Group Media analysis; more than double the 2.49 percent from search traffic and eight times the 0.59 percent from social media. Email remains the highest-ROI channel for Australian SMBs by a wide margin.

Why do Australian emails perform better than the global average?

Three factors explain the gap. First, Australian consumers have higher digital literacy and email maturity than many comparable markets. The ABS reported in 2024 that ninety-three percent of Australian businesses use the internet for business operations, and email remains the primary communication channel for B2B and considered B2C purchases. Second, the market is smaller and more concentrated. Major ESPs (Mailchimp, ActiveCampaign, Vision6, Campaign Monitor) have invested heavily in Australian infrastructure and compliance tooling: SPF, DKIM, DMARC adoption is higher here because the ACMA enforces the Spam Act 2003 with real penalties. Third, Australian small businesses tend to send fewer but more targeted campaigns. The MailerLite data shows Australian senders average lower weekly frequency than North American counterparts, which preserves list health and sender reputation.

What benchmarks should your business actually use?

Industry averages are a starting point, not a target. A plumbing business in Western Sydney with a three-thousand-contact list built over five years will not and should not match the open rates of a national fashion retailer sending daily promos to two million subscribers. List size, list age, send frequency, business model (B2B versus B2C), and price point all shift the baseline. The MailerLite data breaks benchmarks by industry vertical. Professional services sit around 35 percent open rate and 2.1 percent click rate. Retail and ecommerce push closer to 45 percent and 3.2 percent. Health and wellness can exceed 50 percent open rates because recipients actively want the content. Your benchmark is the trajectory of your own list over the past twelve months, measured against the vertical average for your list size bracket.

How to diagnose whether your email performance is actually a problem

Start with deliverability. If your bounce rate exceeds two percent or your spam complaint rate tops 0.1 percent, no subject line tweak will fix the underlying issue. EmailTooltester's 2025 deliverability study found nearly one in six marketing emails never reaches the inbox. Australian senders using ActiveCampaign, ConstantContact, GetResponse, Moosend, or CleverReach averaged above 90 percent deliverability. HubSpot and Omnisend users fell below 80 percent. Check your sender authentication, clean inactive subscribers quarterly, and implement double opt-in for new signups. Once deliverability is sound, compare your twelve-month rolling open and click rates against the vertical benchmark for your list size. A consistent gap of more than five percentage points on open rate or one percentage point on click rate warrants investigation, not panic.

FAQ: Common questions about email benchmarks

What is a good open rate for email marketing in Australia?

A good open rate depends on your industry and list size. Professional services should aim for 30 to 35 percent. Retail and ecommerce can target 40 to 45 percent. Health and wellness often exceed 50 percent. The national average across all industries sits around 21.5 percent according to Vision6, but that figure includes very small and very new lists. If your list has been active for over a year and you send weekly or fortnightly, you should exceed the average by at least ten points.

How often should a small business send marketing emails?

The data shows Australian senders perform best at one to two emails per week. Daily sends erode open rates by three to five percentage points per additional weekly send. Monthly sends lose momentum — subscribers forget who you are and engagement drops. The sweet spot is fortnightly for service businesses and weekly for retail, provided every email has a clear purpose and a single call to action. Test your own cadence by holding frequency constant for eight weeks, then adjusting by one send per week and measuring the four-week impact.

Should I buy an email list to grow faster?

No. Purchased lists destroy sender reputation, trigger spam filters, and violate the Spam Act 2003. The ACMA can fine businesses up to 2.22 million dollars per breach. Built lists grow slower but convert at four to six times the rate of purchased contacts. Invest in lead magnets, website capture forms, and in-person collection at events instead. The fifteen minutes you spend verifying a new subscriber at point of capture saves weeks of deliverability repair later.

The benchmarks exist to orient you, not to define you. An Australian plumbing business converting at 3.8 percent from email is outperforming a national retailer converting at 2.9 percent if the plumber's customer lifetime value is five times higher. Track your own twelve-month trajectory. Compare against your vertical for your list size. Invest in deliverability first, creative second, frequency third. And if your numbers look weak this quarter, remember — the channel still converts at double the rate of search. The problem is usually the list, not the medium.
