By understanding your audience through a centralized view, you can track key metrics that help you monitor growth. For example, key metrics like audience size, engagement, and consent can help you monitor engagement trends and identify opportunities to optimize your strategy.

Challenge

Without unified data and clear audience insights, it’s hard to know what’s really happening with contacts, especially in the awareness stage. Are you attracting the right people or losing them before they engage? Are your messages building interest or driving fatigue? If you can’t track how your audience and/or list is growing or how contacts are interacting with your brand, you’re left guessing about audience health. That makes it nearly impossible to understand which segments to target, how they're performing, and how to eventually drive retention.

Goal

Get a clear view of how your audience is growing and how your new contacts are engaging with your brand. Use engagement indicators, such as open and click-through rates, together with on-site behavior and conversion metrics, to evaluate list quality. With the right insights, you can optimize your engagement channels, adjust message cadence, and prioritize the segments that show the most potential.

KPIs to track:

Net change to subscribers
Engagement rate of new contacts vs total contacts
Bounce and unsubscribe rate
Message fatigue across channels
Ratio of new contacts who become first-time customers

Best practices for measuring new contact engagement

Understanding the quality of new contacts is key to maintaining a healthy audience for your campaigns. By tracking engagement and identifying behavioral signals, marketers can improve audience and list growth strategies and reduce churn risk. These best practices offer a starting point for evaluating new contact engagement and strengthening long-term performance.

Track new contact growth alongside engagement rates
Don't just measure how many people subscribed — track how many of them are opening emails, clicking links, or taking action in the first few days or weeks.
Compare acquisition sources to identify high-performing channels
Segment new contacts by where they came from (e.g., social ads, website pages, gated content) and evaluate which sources deliver the most engaged, high-quality subscribers.
Use behavioral signals to gauge in-market intent
Look beyond email metrics. Monitor on-site activity like product views, cart additions, or search behavior to identify contacts showing buying signals early.
Monitor message fatigue and unsubscribes
Evaluate how often new contacts are being messaged and whether that volume is leading to opt-outs or disengagement. Use fatigue trends to adjust your send cadence.
Prioritize quality over quantity in audience and list building
Focus on lead sources that consistently deliver contacts who engage and convert. Suppress low-engagement segments to improve deliverability and campaign performance.

Situation
You recently launched a referral program that brought in a wave of new contacts through friend-forwarded links and promo codes.
Marketing Opportunity
Use the audience health dashboard to assess how these referred contacts are performing compared to your core audience. Track engagement levels, in-market interest, and unsubscribe rates to understand whether these contacts are likely to convert or just pass through. If they’re showing strong early activity, build a follow-up segment with tailored messaging and incentives to encourage their first purchase or action. If engagement is low, explore whether the referral offer needs to be adjusted or if timing is a factor in their response.
