AI improves email ROI in 2026 by dynamically optimising email content and delivery based on individual recipient behaviour, moving beyond segmentation to true personalisation at scale. This is achieved through machine learning algorithms analysing vast datasets to predict engagement and maximise conversion rates.
As of December 2025, platforms like Campaign Monitor and Klaviyo now include AI-powered features such as send-time optimisation, which uses historical data to determine the optimal time to deliver emails to each subscriber, increasing open rates by an average of 12% according to recent platform data. In 2026, these platforms are expanding to incorporate generative AI for subject line and body copy variations, A/B testing thousands of combinations automatically. Furthermore, AI-driven content blocks are becoming standard; these dynamically adjust product recommendations or offers based on a customer’s browsing history and purchase patterns. Australian data privacy regulations (like the Privacy Act 1988) are addressed through anonymised data processing and consent management features integrated within these platforms. Some platforms are also beginning to offer AI-powered suppression list management, identifying and removing inactive or potentially harmful email addresses to improve sender reputation and deliverability, crucial for avoiding spam filters used by Australian ISPs like Telstra and Optus.
Ultimately, AI functions by continuously learning from email interactions to refine targeting, content, and timing, resulting in more relevant and effective email campaigns.
