How Can Businesses Reduce the Unsubscribe Rate in Their Email Marketing?
Email marketing remains one of the most powerful and cost-effective digital tools for businesses of all sizes. However, one of the biggest challenges brands face—especially as their email list grows—is managing unsubscribe rates. An increasing unsubscribe rate can damage list health, lower engagement, and reduce your overall return on investment.
The good news is that unsubscribe rates are often preventable with the right strategy. At Marketing Together, one of the leading email marketing agencies supporting businesses across Australia, we’ve helped brands reduce churn and maintain highly engaged subscriber lists.
So, how can businesses reduce the unsubscribe rate in their email marketing? Below are the most effective strategies that any organisation can implement—whether you’re working with an email marketing agency Melbourne based or running your campaigns in-house.
One of the primary reasons people unsubscribe is irrelevant content. When subscribers receive messages that don’t align with their interests, they quickly disengage.
Segmenting your list allows you to target subscribers based on:
Purchase history
Demographics
Behaviour (e.g., opens, clicks)
Interests or preferences
For example, if someone subscribes to receive updates about your skincare line, they shouldn’t be bombarded with content about pet products. Personalisation through segmentation shows your subscribers that you understand their needs—something the top email marketing companies in Australia prioritise in every campaign.
Many unsubscribe issues stem from mismatched expectations. Did the subscriber think they’d receive a monthly newsletter but end up getting three emails per week?
To avoid this, clearly communicate what kind of content and frequency they can expect when they sign up. You can do this on the opt-in form, the thank-you page, or in the welcome email.
At Marketing Together, we always help clients establish a welcome sequence that introduces the brand, outlines what’s to come, and builds early trust—a best practice used by most reputable email marketing agencies.
If your emails are consistently helpful, educational, or entertaining, people will look forward to receiving them. But if they’re overly promotional, vague, or lack purpose, unsubscribes are inevitable.
Here are examples of value-driven content:
Tips or tutorials related to your product/service
Early access to offers or launches
Industry news or insights
Customer success stories
Focusing on value over volume is what sets great campaigns apart. Leading email marketing agency Melbourne firms know that even a single highly relevant email can outperform a series of generic ones.
Finding the right balance in frequency is critical. Too many emails overwhelm subscribers; too few risk them forgetting about your brand altogether.
The ideal send frequency depends on your industry and audience, but always monitor engagement metrics. If you notice open and click-through rates dropping—or unsubscribe rates rising—consider scaling back or offering a frequency preference center.
Allowing subscribers to choose how often they hear from you is a tactic more email marketing companies in Australia are adopting to keep their lists healthy.
First impressions matter. Your subject line is often the deciding factor between an opened email and an ignored (or deleted) one.
Tips for better subject lines:
Use the recipient’s name when appropriate
Spark curiosity or create urgency
Test emojis or humour (if aligned with your brand)
Avoid spammy phrases like “Buy now” or “Act fast”
When your email consistently delivers what the subject line promises, subscribers are more likely to remain engaged—something we coach all of our clients on at Marketing Together.
Trying to hide your unsubscribe link is a surefire way to annoy users—and it won’t stop them from leaving. In fact, it might make them mark your email as spam, which can hurt your sender reputation.
Instead, make the unsubscribe link easy to find, but consider offering alternatives:
Reduce email frequency
Change email preferences
Pause emails for a period
By giving subscribers more control, you reduce the chance of permanent disengagement—an approach widely encouraged by modern email marketing Australia providers.
A high unsubscribe rate can also result from poor list hygiene. If you’re emailing people who haven’t engaged with your content in months (or years), you’re more likely to see unsubscribes.
Conduct regular re-engagement campaigns to revive inactive subscribers. If they don’t respond, remove them from your main list or move them into a lower-frequency segment.
Maintaining a clean list ensures better engagement metrics and helps you avoid sending to people who aren’t interested. This is especially important for businesses scaling their email marketing efforts or investing in email marketing jobs within their team.
Don’t ignore your unsubscribe metrics. Regularly review where and when people are opting out. Did a spike occur after a specific email? Was it sent too soon after the last one? Was the content off-brand?
Many email marketing platforms provide insight into:
Unsubscribe rates per campaign
Time between open and unsubscribe
Reason for unsubscribing (if provided)
Understanding the “why” behind unsubscribes helps you make informed changes. At Marketing Together, we include unsubscribe analysis as part of our reporting and strategy reviews—one reason why we’re considered one of the more data-driven email marketing agencies.
Sometimes, even small tweaks can make a big difference in keeping subscribers engaged.
Test variations in:
Subject lines
Email layout
Calls-to-action (CTAs)
Email timing
Personalisation elements
Use these insights to refine your campaigns and develop a format that consistently performs well for your audience. Email marketing agency Melbourne professionals, including our team, often run regular split tests to continually optimise retention and engagement.
