Newsletter
Email MarketingAlso: Email Newsletter · EDM Newsletter
Quick definition
A regularly published email sent to subscribers with curated content, updates or insights. Newsletters build audience relationships, maintain brand presence and drive repeat visits to a website or offer.
Where it shows up in the data
Editorial newsletters lead with genuine value: insight, analysis, curated content. Promotional newsletters lead with offers and product updates. Audiences tolerate promotional content in editorial newsletters, but not editorial content in newsletters that feel primarily promotional. The framing determines the contract with the reader.
A newsletter is only as valuable as its subscriber list. Growing a list requires consistent content quality and active promotion of the newsletter sign-up. A list of 500 genuinely engaged subscribers outperforms a list of 5,000 disengaged ones on conversion.
Newsletters build trust through consistency. A weekly newsletter that arrives every Tuesday teaches readers to expect and look for it. Irregular publishing trains readers to ignore it. Frequency commitment is one of the most important newsletter decisions.
What it actually means
A newsletter is a regularly sent email to a subscribed audience with curated content, insights, updates or a combination. Unlike promotional emails, newsletters are explicitly valued by readers for the content itself rather than an offer. They're a relationship asset: a direct channel to an audience that has explicitly consented to hear from you, unmediated by algorithms. From a marketing perspective, newsletters serve multiple functions: retaining customers and prospects in the consideration window, demonstrating expertise, driving repeat traffic to fresh content and building the kind of familiarity that accelerates trust.
The best newsletters aren't the most comprehensive. They're the most consistent.
How it shows up
Newsletter health shows up in open rate (is the subject line and sender trust working), click rate (is the content compelling enough to drive action) and list growth rate (is the newsletter valuable enough that people subscribe and refer others). Declining open rates signal either audience fatigue, inbox deliverability issues or content relevance drift.
The Australian context
Australian newsletters face SPAM Act compliance requirements, specifically the Australian Spam Act 2003. All commercial electronic messages must have clear identification of the sender, explicit opt-in consent and an easily accessible unsubscribe mechanism. There are civil and criminal penalties for violations. Platforms like Klaviyo, Mailchimp and Campaign Monitor handle compliance infrastructure but marketers are responsible for maintaining consent records.

Common questions
How often should I send a newsletter?
Weekly is ideal for building habit and expectation in readers. Fortnightly is the practical minimum for most small teams. Monthly risks becoming irrelevant between editions. Whatever you choose, consistency matters more than frequency.
What's a good open rate for an Australian newsletter?
It varies by industry and audience. B2B newsletters average 25 to 35 percent. B2C averages 20 to 28 percent. A genuinely engaged, opted-in list with strong subject lines can reach 40 to 50 percent. If you're below 15 percent consistently, investigate deliverability and list hygiene first.
Do I need permission to send newsletters in Australia?
Yes. The Australian Spam Act 2003 requires explicit consent from recipients before sending commercial electronic messages, including newsletters. You must provide clear sender identification and an easy unsubscribe mechanism. Purchased email lists are almost always non-compliant.
