An Introduction to Sunset Notifications the Right Way

Sunset notifications are a strategic tool used to re-engage inactive users before removing them from your communication channels. By implementing a well-crafted sunset notification strategy, you can maintain a healthy user base and improve overall engagement.

What Are Sunset Notifications?

Sunset notifications are messages sent to users who have shown signs of inactivity, such as not opening emails or using an app for a certain period. These notifications serve as a final attempt to re-engage users before they are removed from your mailing list or other communication channels.

Why Are Sunset Notifications Important?

Implementing sunset notifications helps in maintaining a clean and engaged user base. By identifying and re-engaging inactive users, you can improve your sender reputation, reduce unsubscribe rates, and enhance overall engagement metrics.

Best Practices for Implementing Sunset Notifications

  1. Identify Inactive Users

Begin by segmenting your user base to identify those who have not engaged with your content over a specified period. This could include users who haven't opened emails or used your app within a certain timeframe.

  1. Craft Compelling Content

Design your sunset notifications to be engaging and personalized. Use the recipient's name and reference their past interactions to make the message more relevant. Clearly state the value of re-engaging and the benefits they will receive.

  1. Set a Clear Call-to-Action (CTA)

Include a direct and actionable CTA in your notification. Whether it's updating preferences, completing a profile, or exploring new features, make it easy for users to take the next step.

  1. Limit the Number of Notifications

Avoid overwhelming users with multiple messages. A sequence of 2-3 emails spaced 3-7 days apart is often effective. This approach gives recipients time to respond without feeling inundated. (melusine.studio)

  1. Personalize the Message

Personalization increases the likelihood of re-engagement. Use data such as the user's name, past behavior, and preferences to tailor the message. For example, referencing a product they viewed or a feature they used can make the notification more compelling.

  1. Optimize Timing and Frequency

Send notifications at times when users are most likely to engage. Avoid sending messages during late-night hours unless your audience is active at that time. Be mindful of the frequency to prevent notification fatigue. (help.klaviyo.com)

  1. Test and Analyze

Regularly test different approaches to see what resonates best with your audience. Monitor open rates, click-through rates, and conversion rates to assess the effectiveness of your sunset notifications.
