User onboarding is not a one-size-fits-all solution and should be tailored to different user personas and stages of engagement with the product. The three-fold approach to onboarding includes Product Onboarding, Success Onboarding, and Re-Onboarding. Product Onboarding focuses on rapid realization of product value for new users, while Success Onboarding educates returning users on achieving success through new or existing features. Re-Onboarding aims to re-initiate engagement with users who have not been engaged for a long time. It is crucial to experiment, track, and iterate user onboarding strategies to ensure their effectiveness in driving sustainable long-term growth.
