In an era dominated by social media, AI-driven ads, and ever-evolving digital platforms, it’s natural to question the relevance of email marketing. However, in 2025, email marketing not only remains effective but continues to be a cornerstone of successful digital strategies, especially in New Zealand.
Email marketing is a form of direct digital communication where businesses send emails to a targeted audience to promote products, share valuable content, build relationships, and drive customer action. It’s used to nurture leads, retain existing customers, announce promotions, and deliver personalised content based on user behavior or preferences.
Unlike social media or paid advertising, email marketing allows brands to speak directly to individuals who have opted in making it one of the most cost-effective and conversion-driven marketing channels you can use.
Email marketing consistently offers one of the highest returns on investment (ROI) among digital channels. In New Zealand, businesses are seeing an average return of $36 for every dollar spent on email marketing. Notably, 18% of companies report generating $70 in revenue for every $1 invested.
This impressive ROI stems from email’s direct reach, low cost, and ability to deliver personalised content that resonates with recipients.

These metrics underscore email’s capacity to engage audiences effectively, particularly when campaigns are tailored to specific segments.
Modern email marketing leverages personalisation and automation to enhance engagement:
By utilising data analytics and AI, businesses can craft messages that resonate on a personal level, fostering stronger connections with their audience.
With over half of all web traffic coming from mobile devices, optimising emails for mobile is no longer optional. In New Zealand, 71.6% of consumers are likely to delete emails that don’t display correctly on their mobile devices.
Ensuring that emails are mobile-friendly enhances user experience and increases the likelihood of engagement and conversion.
