Can you share some growth hacking tactics that work for boosting product adoption?

Some of the things I think about for boosting product adoption include:

1. In-product notifications and promotions, starting first with onboarding and milestone-related campaigns
2. Product and feature Cross-Sell and Upsell
3. Co-marketing and partnership opportunities
4. Email drip campaigns, including those that celebrate customer milestones
5. Push notifications
6. Organic social media outreach, namely featuring customer stories to ground in social proof
7. Influencer marketing promotions with expiration dates
8. Running A/B tests to determine the most effective marketing messaging and calls to action.

The magic here is getting very specific as to the steps that are required to achieve 'hello world' and sophisticated adoption. Is there a key integration step that is causing most customers to get stuck on their adoption journey? Are they only getting to the point of a basic use case, and not experimenting with more sophisticated outcomes -- why? Are they unaware they can do so? Are they feeling overwhelmed by how to get started?

If you deeply understand the granular steps required to get to 'adoption', it'll become much more obvious where the friction (or acceleration!) points are in the journey, so you can quickly diagnose and take action on resolving those pain points. The resolution could require a range of solutions: an in-product guide that shows where the API keys are to set up that integration; a post-sales playbook to help a customer understand why and how to set up your SDK; a set of new templates or guides to show the art of the possible (and reduce fear of a blank canvas); and so on. From there, it's all about measurement and iteration!
