How publishers can grow their audience and build loyalty with zero- and first-party data

Building a loyal, engaged audience starts with first- and zero-party data, but collecting data isn’t enough. Sailthru by Marigold and Marigold Grow help publishers turn insights into personalized reader experiences, higher opt-in rates, and stronger retention.

Discover how leading publishers are using data to drive engagement and long-term loyalty.

The data dilemma for publishers

Today’s publishers face a growing challenge: building and maintaining direct relationships with their readers in a rapidly evolving digital landscape. With third-party cookies fading and privacy regulations tightening, traditional audience growth tactics are becoming less effective. At the same time, readers expect more control over their data and more personalized experiences.

To succeed, publishers must go beyond passive audience acquisition and focus on creating meaningful, long-term connections. This means using zero- and first-party data to capture opt-ins and build trust, engagement, and loyalty at every touchpoint.

Many publishers struggle with:

  • Encouraging readers to opt in and share their preferences.
  • Using data to strengthen audience trust and engagement.
  • Personalizing content and experiences without adding complexity.

Without a clear audience growth strategy, publishers risk losing readers to competitors who better understand and engage them.

Zero- and first-party data: The key to sustainable audience growth

Zero- and first-party data allow publishers to understand their readers better and build stronger relationships.

  • First-party data is collected through engagement signals: newsletter sign-ups, website activity, and subscriptions.
  • Zero-party data (ZPD) is voluntarily shared by readers: stated preferences, content interests, and engagement choices.

Why it matters:
Instead of making assumptions about what readers want, publishers can use declared preferences to create more relevant, engaging experiences – leading to higher retention, stronger trust, and long-term loyalty.

Building a bigger, more engaged audience with data-driven opt-ins

A strong email and subscriber list is critical for publishers looking to future-proof their audience growth. But getting readers to opt in requires more than just asking. It demands a compelling reason to engage.

How to increase opt-ins and build reader loyalty:

  • Compelling incentives – Offer exclusive content, behind-the-scenes access, or ad-free reading.
  • Clear value propositions – Clearly communicate what readers will gain from subscribing.
  • Progressive profiling – Use short, engaging preference surveys to refine personalization over time.
  • Multi-channel promotion – Use pop-ups, social media, and on-site prompts to encourage opt-ins.

The psychology of subscription growth

Why do readers opt-in? Beyond incentives, trust and relevance play a crucial role. 

Readers are more likely to subscribe when:

  • They perceive ongoing value (high-quality, exclusive content).
  • The sign-up moment feels natural, such as after finishing a relevant article.
  • They feel in control of their preferences, knowing they can update them anytime.

Hypothetical Example: A media company could use Sailthru’s AI-powered segmentation to analyze reader behavior and identify engagement patterns. For example, it could find that readers who finish three or more long-form articles are significantly more likely to subscribe. With this insight, they could trigger a personalized opt-in prompt at the right moment, increasing sign-up rates.

Why it matters:
Readers won’t opt in unless they see real value. According to Marigold’s 2025 Consumer Trends Index, 68% of consumers are willing to pay more for brands they love, yet 37% have switched brands in the past year. Personalization builds reader loyalty, reducing churn and increasing retention.

From passive readers to engaged subscribers

Most publishers collect audience data, but few effectively use it to create meaningful, lasting reader relationships.

Sailthru by Marigold + Marigold Grow makes it easy to turn passive website visitors into engaged subscribers without adding complexity.

How publishers can use data to build loyalty:

  • Preference-based content streams – Let readers subscribe to content that genuinely interests them.
  • Interactive data collection – Use polls, preference quizzes, and gamification to capture audience insights.

Engagement-triggered experiences – Send personalized newsletters, follow-ups, and recommendations based on real behavior.

Data transparency and why it drives opt-ins

Modern consumers are more protective of their data than ever, but they’ll share it if they trust how it’s being used.

Best practices for transparent data collection:

  • Be upfront about data use – Explain why you’re collecting preferences and how it benefits the reader.
  • Offer control Respect customers’ rights to access or delete their data through Grow’s Data Protection Center.
  • Show immediate value – Don’t just collect data. Use it to personalize experiences right away.

The shift from audience growth to reader loyalty

Growing a subscriber list is just the first step. Publishers need to nurture those relationships with data-driven engagement strategies.

How publishers can turn subscribers into loyal readers:

  • Personalized content recommendations – Offer AI-driven suggestions based on reader preferences and behavior.
  • Cross-channel activation – Deliver consistent experiences across email, web, and mobile.
  • Re-engagement campaigns – Automate personalized outreach to keep readers engaged at pivotal moments.
  • Trust-driven personalization – Use stated preferences to deliver content readers actually want rather than relying on tracking and guesswork.

Why it matters:
Most publishers fail to act on the data they collect. Sailthru by Marigold + Marigold Grow makes it easy to turn insights into meaningful, loyalty-building experiences.

The future of publishing beyond traffic toward membership

The media landscape is shifting to membership-driven models. Instead of focusing purely on traffic, publishers are investing in reader relationships.

Emerging trends include:

  • Subscription bundles – Offering personalized subscription tiers instead of one-size-fits-all plans.
  • Exclusive communities – Creating membership-driven models with VIP perks.
  • Loyalty-driven monetization – Using engagement data to drive sponsor-backed, premium experiences.
