How to Boost SaaS Retention by 30% With AI-Powered Email Marketing

In this article

Customer acquisition costs keep rising, and the SaaS industry is feeling the pressure. Retention is no longer a secondary metric — it has become the new growth engine. During our latest webinar, Wenddy Dias, Marketing Manager at Albato, and Valeriia Klymenko, Head of Business Development at UniOne and Business Development Manager at Selzy, shared how AI-driven email marketing is transforming the way SaaS companies communicate, engage, and retain customers.

In this article, we break down the core insights from the session and show how AI-powered email automation can increase SaaS retention by 30% or more and help you boost key business metrics.

The new era of AI-driven email marketing

Email remains the most controllable, high-ROI channel in SaaS marketing. While social platforms and paid ads fluctuate, email is stable, direct, and reliable — and its audience keeps growing. By 2028, the number of global email users is expected to exceed 4.9 billion.

What has changed is how SaaS companies use email:

• AI predicts churn and optimal timing

• Generative AI personalizes messages at scale

• Adaptive workflows adjust content based on real-time user behavior

As a result, you have automated email that feels as relevant as human-written messages — only faster, more scalable, and far more profitable.

Also, learn how to encourage your users to learn AI prompting.

Is email still the backbone of SaaS communication?

Email touches every part of the customer journey — onboarding, activation, transactional alerts, education, expansion, renewal, and beyond.

Unlike other channels, email:

• Works regardless of device, region, or interface
• Belongs to the SaaS company, not an external algorithm
• Functions as both a transactional and engagement layer

In other words, email marketing automation is where product value meets customer action.

How AI supercharges email for SaaS retention

In 2025, AI transforms email from a static communication tool into a proactive retention mechanism. It:

• Detects churn signals based on behavior

• Creates personalized content in seconds

• Optimizes delivery for each segment

• Adjusts campaign frequency to prevent fatigue

• Forecasts upgrades, renewals, and upsell opportunities

This is not theory — it's already happening in leading SaaS ecosystems.

Case study: HubSpot’s AI-powered content personalization

Large companies are already using AI tools to streamline their communications. HubSpot tested whether AI could deliver personalized email content that drives real results. Here’s what they did:

1. Collected key data: business URL, company size, and content interest.

2. AI analyzed the lead’s website and behavior.

3. It summarized the user’s intent and goal.

4. It imagined the ideal content for that objective.

5. It searched HubSpot’s library using vector matching.

6. AI generated a tailored message explaining the value.

The results were staggering:

• +82% conversion rate
• +30% open rate
• +50% click-through rate

Real-world automation scenarios: Albato + UniOne and Selzy

During the webinar, we showed how SaaS companies combine Albato’s no-code automation with UniOne and Selzy’s email infrastructure to build AI-powered retention pipelines:

• Transactional emails triggered from backend events and sent via UniOne

• Personalized onboarding sequences activated through Google Forms

• AI-generated webinar campaigns powered by Selzy, HubSpot, and OpenAI

• Embedded white-label automations directly inside SaaS products via Albato modules

When AI and automation combine, consistency, timing, and personalization become effortless.

Summing up

To retain customers in 2025 and beyond, SaaS companies need more than campaigns — they need intelligent email strategies with AI that improve:

• Segmentation

• Personalization

• Customer Journey Mapping

• Automated Campaign Management

With so many technologies available, companies can feel lost about where to begin their optimization efforts. Rely on the right tools, run tests, and keep a close eye on analytics to understand what truly resonates with your audience. A strong starting point is combining automation with AI — and enabling your users to expand their own ecosystems as well.
