Mobile app builders and marketers: Share best tools for creating effective user journeys

I was working at Koo (a social media app which was an alternative to Twitter). At Koo, we used CleverTap. Similarly, I have worked with 7-8 social media companies that had tools like MoEngage, WebEngage, MixPanel, etc. for analytics, in-app and push notifications, emails, etc. I haven't specifically found a good product that is effective for creating user journeys. Does anyone have any tips or best practices for creating effective user journeys? What tools do you use? Share in the comments. P.S. I have added my recommendation in the comments as well. :)
