Direct answer
DevTool outbound works better when account selection and messaging are based on technical signals such as repository activity, dependencies, issues, migrations, stars, forks, and developer ecosystem behavior.

Before personalization, you need account relevance. GitHub and developer ecosystem signals can show why an account might care now.
