Why email newsletters are making a comeback with personalisation

Executive overview

Generic email blasts have lost effectiveness. Segmented, personalised newsletters now deliver dramatically higher open and click rates.

AI tools make audience-specific personalisation cheap enough to apply at scale — newsletters work again when each segment gets a tailored message.

Why newsletters fell and why they're rebounding

• Generic mass emails no longer convert the way they once did
• Personalisation is the deciding factor — segment your list, tailor each message
• AI tools (ChatGPT etc.) make producing multiple customised variants fast
• First-party data collection (email, SMS) is now a core strategic priority — "easy mode is off"

How to implement segmentation from day one

• Tag new subscribers at the point of capture based on the content they arrived from
• One tag per interest category (SEO, affiliate marketing, paid ads, social media)
• Use that tag to determine which email variant they receive
• Aim for 8–10 distinct variants sent as a single coordinated blast

Emerging technology: buying inside the email

• A new tool allows customers to complete a purchase without leaving the email
• Example: select product colour, size, and check out directly inside the message
• Eliminates the drop-off caused by redirecting to a website
• Expect newsletter conversion rates to rise sharply as this spreads
