Email Personalization Guide: Beyond First Name Tokens

Adding someone's first name to an email is not personalization. It is a merge tag. True personalization creates unique, relevant experiences for each subscriber. Here is how to do it properly.

Levels of Personalization

Level 1: Basic Merge Tags

The baseline that everyone does:

• First name in subject line or greeting
• Company name
• Location

This is table stakes. It shows minimal effort and subscribers expect it.

Level 2: Segmented Content

Different content for different groups:

• Industry-specific examples
• Role-based messaging
• Customer stage content

More effort but significantly more effective.

Level 3: Behavioral Personalization

Content based on individual actions:

• Products they viewed
• Features they used
• Content they consumed
• Emails they engaged with

This is where real personalization begins.

Level 4: Predictive Personalization

AI-driven content selection:

• Predicted interests
• Likely next actions
• Churn risk-based messaging
• Optimal send time per subscriber

Platforms like Sequenzy use AI to enable this level of personalization without requiring data science expertise.

Personalization Techniques

Dynamic Content Blocks

Show different content sections based on subscriber attributes:

• Product recommendations based on purchase history
• Case studies from their industry
• Pricing in their currency
• Images that match their preferences

One email template, multiple personalized versions.

Behavioral Triggers

Send emails triggered by specific actions:

• Browse abandonment: "Still interested in X?"
• Cart abandonment: Reminder with the specific items
• Purchase follow-up: Related products or tips
• Milestone reached: Celebrate achievements in your product

Progressive Content

Adapt content based on subscriber journey:

• New subscribers see introductory content
• Engaged leads see deeper product information
• Customers see usage tips and upsells
• Power users see advanced features

Time-Based Personalization

Adapt to subscriber timing:

• Send at their optimal open time
• Reference time since last interaction
• Countdown timers that update per viewer
• Content that changes based on time of day

Data for Personalization

First-Party Data

Data you collect directly:

• Sign-up form responses
• Preference center selections
• Purchase history
• Website behavior
• Email engagement
• Product usage

Derived Data

Insights you calculate:

• Engagement score
• Customer lifetime value
• Predicted churn risk
• Product affinity

Enrichment Data

Data from external sources:

• Company information
• Industry classification
• Technology stack
• Social profiles

Personalization in Practice

Subject Line Personalization

Beyond first names:

• "Your weekly [Industry] insights"
• "Based on your interest in [Topic]"
• "[Product Name] tips for week 3"
• "Complete your [Action Started]"

Body Content Personalization

Make the content feel individually crafted:

• Reference their specific situation
• Use examples from their industry
• Show relevant products or features
• Acknowledge their history with you

CTA Personalization

Adapt calls-to-action:

• New leads: "Start free trial"
• Trial users: "Upgrade now"
• Customers: "Add this feature"
• Churned: "Come back and save 20%"

Common Mistakes

Creepy Personalization

Avoid making subscribers uncomfortable:

• Do not reference data they did not knowingly share
• Be careful with location-based messaging
• Do not be too specific about browsing behavior

A good test: would this feel helpful or intrusive?

Broken Personalization

Always have fallbacks:

• "Hi {{first_name}}" failures look worse than no personalization
• Test with missing data scenarios
• Use sensible defaults

Irrelevant Personalization

Personalization without purpose:

• Adding names when it does not add value
• Referencing old data that is no longer relevant
• Personalizing minor elements while ignoring major ones

Measuring Personalization Impact

Track how personalization affects:

• Open rates (personalized subject lines)
• Click rates (personalized content)
• Conversion rates (personalized offers)
• Revenue per email
• Unsubscribe rates

A/B test personalized vs non-personalized versions to quantify impact.

Getting Started

Start with high-impact, low-effort personalization:

1. Segment-based content: Different emails for different customer stages
2. Behavioral triggers: Cart abandonment, browse abandonment
3. Dynamic product recommendations: Based on purchase history
4. Optimal send time: Let AI determine when each subscriber opens

Tools like Sequenzy make advanced personalization accessible with AI-powered features that automate much of the complexity.
