AI & Email Personalization

As someone who has worked with email marketing for years, we’re always striving to craft messages with a compelling value proposition that truly connects with each recipient.

But let’s be honest—it’s impossible to do this at scale. At least, if you’re human.

For years, the standard marketing approach was to group people based on similar pain points or characteristics and do our best to create content that resonated with them. 

The hope was that, over time, they would recognize that we had the solution they were looking for.

Now, AI has changed the game. It can personalize one-to-one messages at scale, reaching thousands of recipients faster than any human ever could.

Take ActiveCampaign, for example—their AI can identify customers likely to churn and automatically segment them for targeted retention campaigns. 

Once these segments are created, AI then crafts tailored messages for each group, making communication more effective.

Of course, this doesn’t mean email marketers are obsolete—you’ll still need experts to review, refine, and optimize what AI produces

But there’s no doubt AI makes the process faster, smarter, and more scalable.

AI & Email Performance

Platforms with built-in AI, like Resquared, offer features such as the AI Template Rating, which analyzes your email and pinpoints exactly what needs improvement, why, and how to fix it with actionable suggestions.

The AI evaluates key elements, including:

  • Email length – Ensuring it's concise and engaging
  • Spam triggers – Identifying content that might flag your email as spam
  • Value proposition – Assessing clarity and effectiveness
  • Personalization – Checking if the email feels tailored to the recipient
    Best practices – Ensuring compliance with industry standards

With AI-powered insights, you can refine your emails for higher deliverability, and improved response rates—without the guesswork.

AI & Lead Scoring

AI lead scoring helps you focus on the most promising leads by analyzing key data points such as email interactions, website behavior, and purchase patterns.

Take HubSpot, for example—they use:

  • Engagement Score – Qualifies leads based on actions like subscribing to a newsletter, opening an email, or clicking a CTA.
  • Fit Score – Evaluate leads based on demographic information to determine how well they match your ideal customer profile.

There are many ways to incorporate AI into your campaigns, but instead of juggling multiple tools, you need a complete solution.

Measuring the Impact of AI

Keep an eye on these metrics to evaluate the impact of AI in your campaigns:

In Resquared Communication Center, you can track all the messages you’ve sent, and filter by contacts who opened your email, replied, and those you've marked as leads.

Monitoring open rates, response rates, and conversions is essential for understanding the return on investment (ROI) of your AI efforts.

Are AI emails more likely to go to spam?

In one study involving 450 participants, AI-written emails that used plain text, concise subject lines, and minimal formatting consistently reached primary inboxes on Gmail, Yahoo, and Outlook, with zero emails being flagged as spam.

Other research also found that AI emails can outperform human-written ones in engagement, leading to higher click-through and click-to-open rates. 

This suggests that when used strategically, AI can enhance email marketing effectiveness.

So far, there’s no indication that AI-generated emails are more likely to be marked as spamspam filtering depends on other factors

Issues like a poor sender reputation, improper authentication settings, and bad list hygiene are far more likely to impact deliverability than whether an email was written by AI or a human.

At the end of the day, email deliverability is about more than just content

A successful email strategy requires a well-maintained sender reputation, strong engagement metrics, and proper authentication protocols.

How AI Helped HubSpot Boost Email Conversions by 89%

HubSpot’s email personalization strategy relied on segmentation—grouping users based on behaviors, like downloading marketing content, and then sending them related resources. 

While effective to some extent, this lacked true individual personalization.

With AI, HubSpot was able to analyze multiple data points and create 1-1 personalization at scale, moving beyond broad segmentation.

The question: Can AI help us understand what a person is actually trying to accomplish?

Instead of simply sending marketing resources to a general group like “marketing professionals,” HubSpot wanted to identify specific user intents. For example:

  • A marketing manager looking to build an influencer strategy
  • A marketing analyst trying to improve their website’s SEO

To test this, HubSpot built an AI system that analyzed thousands of individual user intents to craft highly personalized emails.

  • The user’s business website
  • The resources they downloaded or blog posts they accessed
  • AI-generated insights on what they were trying to achieve
  • AI-recommended content—either existing from the HubSpot library or newly created—to meet their needs
  • A tailored, personalized email delivering the perfect resource

After months of testing and improving the AI-generated email copy, HubSpot saw impressive gains:

+82% increase in conversion rates
+30% boost in open rates
+50% increase in click-through rates

It wasn’t as simple as just “turning on AI and forgetting about it.” 

A team of professionals continuously monitored and refined the system, ensuring it performed at its best. But in the end, the effort paid off.

What do you think—worth the investment? 

Conclusion

AI is changing the game for email marketing, and staying on top of emerging trends is crucial.

Here are some trends to watch:

  • Advanced Personalization: AI is moving beyond basic segmentation, offering real-time, behavior-driven content tailored to individual actions.
  • Predictive Analytics: AI platforms are improving their ability to detect at-risk customers and trigger re-engagement campaigns with greater accuracy.
  • Enhanced Integration: AI tools are becoming better at syncing with CRMs, boosting lead scoring and campaign management.

The trick is to start small, focusing on high-quality data and respecting customer privacy.

Gradually scale up your efforts and take full advantage of AI's capabilities to strengthen your email marketing strategy for the long haul.
