Boosting App Usage and Revenue Through Engaging Push Notifications
Context
I worked with the digital marketing team at Mango Languages to launch push notifications that would increase usage by mobile app users and drive in-app purchases to access more language content. I developed the content strategy with all of the messaging for the push notifications including variation to A/B test different timing, triggers, and variables.
Goals
- Overall, this was an initiative to drive mobile learning sessions and boost the number of lessons started by users, as this is the main KPI for Mango Languages. 
- Increase app usage for users who downloaded the mobile app but don’t use it, and change inactive users into active users 
- Increase in-app purchases (ability to upgrade to access more language content) 
Result
To make sure our notifications were relevant and useful, we sent a mix of situational notifications where frequency and timing were manually set and behavioral notifications that depended on the user’s activity in the app. Here is a sample:
Welcome Push Notifications
- Automatically triggered 3 days, 7 days, and 15 days (at the end of free trial period) after profile creation or linking a free account via public library, school, or university 
- The goal was to retain users and get them back into the app 
- Encourage conversion to upgraded full-app access after the end of the trial 
Peak Time Push Notifications
- Experimented with different timing: when users are more likely to use their phone; or on specific days of the week. For example: - In the morning, reminder to use Mango during commute to work 
- Before bed, to encourage learners to meet their language goals 
- Specific days: ‘TGIF,’ ‘hump’ day, etc. 
 
- Needed to be fun, engaging, and provide value to users and promote language learning 
- The goal was to put Mango top of mind and increase learning sessions 
Personalized Push Notifications
- Behavior-based push notifications were sent after the user started a lesson or selected a language. For example: - Language-specific notification a few days after a user selected a new language 
- Lesson-specific notifications targeting users who started/finished a specific lesson 
- Helped users meet their goals 
- Reminded users to complete an action 
 
- The goal was to upgrade account to unlock more languages, lessons, etc. 
Reminder Push Notifications
- Targeted users after 15 days, 22 days, and 29 days of inactivity 
- The goal was to re-engage inactive users 
Feature Highlight Push Notifications
- Promote mobile-specific features like downloadable lessons, offline access, auto play, etc. 
- Promote features specific to upgraded accounts like family profiles, multiple languages, etc. 
- The goal is to drive usage to specific features to boost sessions and conversions
