What email tools are best

ROI insights

Keeping your existing customers engaged is often more cost-effective than constantly chasing new ones. For Australian SMEs, a strong customer retention strategy relies heavily on email marketing – but choosing the right tools can feel overwhelming. We’ve seen firsthand what works, and what doesn’t, over the last decade. Here’s our take on the best email platforms to help you nurture those valuable customer relationships.

The ‘best’ tool really depends on your business size and technical expertise. However, several platforms consistently deliver strong results for SMEs focused on retention. We’ll cover a few key options, highlighting their strengths.

  • Mailchimp: Still a solid choice, particularly for businesses starting out. Mailchimp’s free plan is generous, allowing you to build a list and send basic campaigns. It’s user-friendly and integrates well with many e-commerce platforms. However, as your needs grow, costs can escalate quickly, and advanced automation features are limited on lower tiers.
  • Klaviyo: If you run an e-commerce business, Klaviyo is a powerful option. It’s specifically designed for online stores, offering sophisticated segmentation and automation based on customer behaviour – things like abandoned carts, purchase history, and website activity. This allows for highly personalised email flows that drive repeat purchases.
  • Campaign Monitor: A good middle ground. Campaign Monitor offers a balance of features and affordability. It’s easy to use, with a drag-and-drop editor, and provides robust automation capabilities without the complexity of Klaviyo. It’s a strong contender if you need more than Mailchimp offers but aren’t exclusively e-commerce focused.
  • Brevo (formerly Sendinblue): Brevo is increasingly popular, offering email marketing alongside SMS marketing and a CRM. This integrated approach can be incredibly valuable for holistic customer communication. Their pricing is competitive, and they offer a free plan with a daily sending limit.

Beyond the platform itself, remember that deliverability is crucial. Ensure you’re following best practices for email authentication (SPF, DKIM, DMARC) to avoid landing in spam folders. Regularly clean your email list to remove inactive subscribers – this improves your sender reputation and overall campaign performance. Focusing on segmentation is also key. Sending relevant content to specific customer groups dramatically increases engagement.

Ultimately, the best email tool is the one you’ll actually use consistently. We recommend starting with a free trial of a couple of platforms to see which one feels most intuitive and aligns with your business goals. Don’t be afraid to reassess your needs in 2026 or 2027 as your business evolves. A well-executed email retention strategy will pay dividends for years to come.
