Definition
AI personalization is the use of machine learning to tailor email to each recipient. Rather than simple merge tags for a first name, AI predicts what a subscriber is most likely to engage with — choosing content, offers, send times and even subject lines based on behavioural patterns and purchase intent. The result is more relevant email, usually with better opens, clicks and conversions.
What AI Can Personalize
- Subject lines and preheaders
- Content blocks and offers per subscriber
- Product recommendations
- Send time and cadence
- Channel and message sequencing
How It Works
The model learns from each subscriber’s history — clicks, purchases, browsing, engagement recency — and ranks content or offers by predicted response. Personalization updates as behaviour changes, so the email algorithmically adapts to the recipient.
Using It Well
Personalize where it adds relevance, but keep brand voice consistent and safeguard data. Validate that personalization improves results rather than just changing them, and respect privacy and consent around the data the model uses.
