Pro Tips
- *Choose based on your event maturity - if your product events are messy or incomplete, prioritize tools that tolerate iterative instrumentation.
- *Map your first three lifecycle journeys before buying - welcome, activation nudges, and churn-risk rescue usually reveal your real feature needs.
- *Separate transactional needs from lifecycle needs - some teams save money by using one tool for product email and another for journeys.
- *Check how easily developers can pass custom properties, usage events, and workspace-level metadata from your app backend.
- *Favor tools that match your current team size - the most powerful platform is not always the best option for a two-person launch team.
