How AI Personalises Email Marketing

1. AI for Hyper-Personalised Emails

Generic emails don’t work anymore. AI helps businesses create customised emails by analysing:

• Purchase history (what the customer purchased).
• Browsing behaviour (where they looked).
• Demographics (age, place, interests).

Example: If someone leaves their cart behind, AI can email a special discount to get them to make the purchase.

2. AI-Powered Subject Line Optimisation

A subject line is what decides if an email gets opened. AI applications such as Phrasee and SubjectLine.com employ machine learning to:

• Test several subject lines to determine which one works best.
• Anticipate the most compelling phrasing (e.g., “Your special offer is inside!” vs. “Don’t miss this deal”).
• Don’t use spam-inducing words (such as “free” or “urgent”).
• Outcome: Up to 30% greater open rates with AI-optimised subject lines.

3. AI for Dynamic Email Content

AI can dynamically alter email content in real-time depending on who opens it. For instance:

• A travel business displays beach holidays to users in cold weather.
• An online retailer displays winter coats to customers in snowy areas.
• This degree of personalisation raises click-through rates (CTR) by 20-50%.

AI in Email Automation: Intelligent Campaigns

1. AI-Driven Send Time Optimisation

Sending messages at the appropriate time doubles the opens. AI considers when every subscriber is most active and sends messages accordingly. Tools such as Sendinblue and HubSpot leverage AI to:

• Foresee the ideal time to send messages to each user.
• Make adjustments according to time zones and previous interactions.

2. AI for Behaviour-Based Trigger Emails

Rather than blasting the same emails to all, AI triggers emails based on user behaviour, such as:

• Welcome series (on sign-up).
• Abandoned cart reminders.
• Re-engagement emails (for dormant subscribers).

For instance, if a user has not opened emails in 3 months, AI can send a “We miss you” email with an exclusive offer.

3. AI for Intelligent Email Segmentation

All subscribers are not equal. AI assists in segmenting email lists into segments such as:

• Value customers (repeat buyers).
• At-risk subscribers (likely to unsubscribe).
• New leads (just subscribed).

This helps the right message get to the right people.

How AI Enhances Email Open & Click Rates

1. AI for A/B Testing

Rather than manually testing different email versions, AI automatically discovers the best-performing aspects, such as:

• Subject lines
• Call-to-action (CTA) buttons
• Images vs. text-based layouts

Result: Improved optimisation and higher conversion rates.

2. AI-Powered Spam Detection

• AI prevents spam filters by
• Verifying email content for red flags.
• Enhancing deliverability (getting emails into inboxes).

Tools such as GlockApps leverage AI to test emails before sending.

3. AI for Predictive Analytics

AI identifies which subscribers are most likely to convert, allowing companies to concentrate on high-value leads.

The Future of AI in Email Marketing

AI is making email marketing more intelligent and automated. Trends of the future include:

•  AI-written email copy (full emails composed by AI).
• Voice-enabled emails (optimising for smart speakers).
•  Emotional AI (tone adjustment according to user mood).

Companies embracing AI today will remain ahead of the competition.

Conclusion

AI is revolutionising email marketing through increased personalisation, automation, and campaign performance. From AI-composed subject lines to behaviour-driven triggers, companies using such tools notice an increased open rate, more clicks, and ultimately higher sales.

It all begins with taking a step back, starting with AI subject line tools and working your way into automation. Your emails will not get lost in packed inboxes but yield superior performance with the power of AI.
