Referral Program Best Practices: Using In-App Marketing to Drive Participation

One of the key components of an effective referral program is in-app promotion. Product managers play a crucial role in ensuring that users are encouraged to refer friends at key moments within the app. From push notifications to in-app pop-ups, leveraging the right UX touchpoints can significantly boost participation rates and keep users engaged with your app for longer.

Push Notifications: Getting People Into Your Product

Push notifications serve as a powerful tool for encouraging users to interact with your app. Incorporating referral rewards into your notifications can make them even more persuasive.   [caption id="attachment_22201" align="aligncenter" width="320"] Use urgency to amplify the impact of your push notifications.[/caption]

Benefits of Push Notifications

• Instant and high visibility – Notifications appear directly on a user’s device, cutting through inbox clutter and other distractions.
• Encourages app re-engagement – Push notifications coupled with referral rewards remind users of the value of your product and incentivize them to return.
• Drives immediate action – A well-timed push notification with a compelling offer can prompt users to act quickly.

 

Client Success Story

With mobile banking apps occupying only a small portion of users' daily screen time, this finserv client used push notifications to drive users to its app and boost referral program participation. Push notifications kept the app top of mind for customers who were otherwise less likely to casually engage with the product. A ‘limited-time’ referral offer proved especially effective, amplifying the urgency that push notifications naturally create. Push notifications should be just one part of an omnichannel in-app marketing strategy. Using an integration like Iterable can enhance cross-channel communication by enabling targeted and personalized messaging. Iterable uses real-time behavioral data and AI-driven insights to deliver personalized messages at the optimal moment, maximizing customer engagement and activation.  

In-App Notifications: Seamless UX Touchpoints

In-app notifications guide users to take action while they're already engaged with your app, offering a seamless and contextual way to encourage participation.   [caption id="attachment_22243" align="aligncenter" width="249"] Use in-app notifications to drive users to a rewards dashboard where they can see and redeem their referral earnings.[/caption]

Benefits of Leveraging In-App Notifications

• Contextual relevance – Deliver messages at peak engagement moments, seamlessly guiding users to an inbox or dashboard for effortless sharing.
• Longer Visibility – Enhance visibility by displaying a badge counter for notifications to remind users of pending actions while in the app.
• Target audience segments with tailored messaging - Precise targeting can help you tailor in-app marketing to different user demographics. You can use first-party data to power dynamic audiences and experiences through integrations like Braze.

 

Client Success Story

A leading service app leveraged Extole’s integration with Braze to power a targeted in-app notification campaign for its two-sided marketplace. In-app notifications reminded customers when they had referral credits available, so they were more likely to book a service and remain engaged with the app long-term. The client also leveraged Braze for personalized in-app notifications to celebrate top advocates and motivate them to keep sharing with friends. By highlighting their referral progress and additional earning opportunities, in-app notifications reinforced engagement for both users and providers.  

Pop-Ups: Capture Attention Without Disruption

Pop-ups are modal windows that overlay content, ensuring visibility. When used strategically, they can be highly effective in driving referral participation.   [caption id="attachment_22268" align="aligncenter" width="208"] Pop-ups help remind users when they have referral credits available to use.[/caption]

Benefits of Using Pop-Ups

• Command Attention and Engagement – Pop-ups are an effective way to deliver important messages, as they require users to either close or act on them.
• Vehicle for strong visuals and copy - As a larger medium, pop-ups provide the perfect space to showcase your most compelling visuals and persuasive messaging.
• Compel user actions at opportune times - Program pop-ups to appear at transitional moments such as when a user opens the app or navigates to a new page.

 

Client Success Story

A telecom client offering mobile and internet services used pop-ups to drive referrals among customers, employees, and partners. Pop-ups were timed to appear during key events in the user journey to turn moments of engagement into further action. New customers saw a referral program announcement alongside their welcome message, leveraging their initial excitement. Regular users received reminders after paying or checking their bill, while top advocates were recognized with personalized messages offering additional rewards to keep them motivated. Aligning pop-up timing and messaging with each customer segment and their unique goals will amplify the effectiveness of your in-app promotion strategy.  

Product Emails: Extending the Referral Program Beyond the App

While marketing emails focus on promotions and outreach, product emails are directly tied to user actions within the app (e.g., purchase confirmations, feature updates). These provide excellent opportunities to integrate referral messaging.

Benefits of Promoting Referrals Through Product Emails:

• Engage Users Beyond the App – Email marketing extends your reach, keeping referrals top of mind even outside the app.
• Capitalize on moments of excitement - Use email to promote a referral reward while users are already excited, such as following a purchase.
• Higher conversion rates - Emails tend to have higher conversion rates than other forms of messaging for actions that require more consideration, like sharing a referral link.

 

Client Success Story

A subscription service client grew its membership by using personalized product emails to promote its referral program. The client integrated referral CTAs into their onboarding email series, ensuring that each step of the account setup included a reminder of the referral discount, a shareable link, and a progress update on successful referrals. Additional follow-up emails reinforced the message by targeting specific user behaviors. Users who clicked share buttons but didn’t convert received reminders and incentives, while top advocates received milestone emails encouraging them to reach higher reward tiers. This client’s strategic email cadence kept referrals top-of-mind, driving sustained engagement and membership growth.  

Closing Thoughts: The Power of In-App Marketing for Successful Referral Programs

Timely, well-designed in-app marketing is foundational to the success of your mobile app referral program. Referral best practices recommend that at least 10% of new users come from referrals made by existing customers–but with the right promotion, businesses are able to exceed 10%, 20%, or even 30% acquisition through referrals. Leveraging push notifications, in-app messages, pop-ups, and product emails lets brands create impactful referral experiences that increase user engagement and encourage sharing with friends and family.
