Background
Whiteflag is a mental health platform designed to offer real, anonymous support for people struggling with emotional distress. It allows users to connect with others who have experienced similar challenges, fostering a supportive community for those in need. The platform is a lifeline for users navigating mental health struggles, ensuring they can find someone who understands what they’re going through, without fear of judgement.
Challenges
- Low initial user retention rates
- High drop-off rates after initial registration
- Users needing quicker access to support, connection, and mental health resources
Key goals
- Increase retention and engagement rates through personalised, data-driven engagement strategies
- Improve user experience, with a focus on quickly connecting people to real, meaningful support
- Develop targeted messaging to enhance user interaction and connection, especially in the early stages of their journey
Strategy
We focused on creating a data-driven, personalized user engagement approach. We optimized onboarding to ensure users found value and connection within the critical first few days—when mental health support is most needed.
We built a user-centric journey that offered immediate emotional support during vulnerable moments, ensuring no one felt alone. Through customer lifecycle automation, we ensured every user, from first-time logins to returning members, felt connected and encouraged to engage with the app when they needed help the most.
Engagement Campaigns
HIGHLIGHTS
We launched tailored engagement campaigns that targeted specific pain points in user engagement, such as drop-offs after registration and low daily check-ins. These campaigns included:
- Real-time notifications: Personalised push notifications and emails encouraged users to check in, connect with others, and share their experiences, all while providing emotional support and understanding.
- Habit-forming content: Tailored messages reminded users of the importance of sharing their struggles, promoting daily check-ins that reinforce community connections and ensure they don’t feel isolated.

Behavioural Tracking and Data Integration
WhiteFlag’s backend was integrated with Mixpanel and OneSignal to track real-time user behaviour, allowing us to:
- Deliver personalised messages and reminders based on user engagement
- Create behaviour-based engagement journeys to help users find the right support at the right time

Retention and Engagement Improvement
By implementing user engagement journeys focused on helping people feel supported faster, WhiteFlag achieved a
18.6% increase in Day 7 retention and a
12.1% improvement in Day 14 retention - the first two weeks being the most crucial period for users receiving support for their issue. This increased engagement allowed more people to stay connected to the support they needed, reducing the isolation that often worsens mental health struggles.
Impact on Mental Health and Well-Being
Users reported feeling more connected and supported during their mental health journeys. The platform saw a surge in meaningful interactions, with thousands of users expressing how they were able to connect with someone who truly understood their feelings.
These improvements have had a real, measurable impact on users' well-being, as they’ve been able to find faster access to support and meaningful connections. WhiteFlag helps users express what they’re going through, making them feel heard and supported, ultimately improving their mental health outcomes and helping them manage tough times more effectively.
One user shared, “Finding someone who gets what I’m going through changed everything. I didn’t feel so alone, and knowing that others have made it through made me feel like I could too.”
Reduction in Early Drop-Offs
We reduced early drop-offs significantly by making the onboarding and support journey more accessible. The average time for low-intent users to cancel decreased from 5.4 days to 4.9 days, giving WhiteFlag the opportunity to engage users quickly and connect them with someone who could offer immediate help.
Key Metrics:
Day 7 retention: Increased by 18.6%
Day 14 retention: Grew by 12.1%
