If you are growth and lifecycle teams
Growth work lives or dies on targeting and measurement. What matters is whether behavioral triggers can be built without engineering time, whether the event stream supports attribution past the open, and whether deliverability holds when broadcast volume shares a reputation with product email.
The order above is the general editorial ranking. Re-sorted against scheduling, event stream, and operating track record, the shortlist for behavior-triggered journeys, broadcasts, and winback campaigns measured on revenue becomes Customer.io, ActiveCampaign, and Drip. That differs from the headline order, which weighs all audiences together.
