To begin with, it’s crucial to comprehend why 64% of outbound messages receive no responses. With assistance from the data science team, I would analyze the data to identify specific issues. My goal would be to gather data points such as the timing of messages, content of the messages, and the activities of both the sender and recipient. If the timing of messages is problematic, we could introduce features that suggest the optimal time to message based on the recipient's activity. If the content of the messages is an issue, perhaps they are too generic; we could provide tips for crafting effective messages or offer personalized message templates. In terms of user-related challenges, we could enhance targeting by recommending users to message based on their activities, professions, interests, and more. Additionally, for users who are less active or new to the platform, we could improve the onboarding process or implement features that encourage greater engagement. All of these implementations would necessitate collaboration across different teams, so I would coordinate with user experience, engineering, and marketing teams to ensure the plan is executed effectively.
