Top 8 Customer Engagement Platforms for Product-Led SaaS in 2026

In 2026, the landscape of customer engagement platforms for product-led SaaS companies is defined by the need to balance speed, control, and infrastructure capabilities. With cross-channel messaging sitting at the intersection of engineering, product, and marketing, various platforms are designed to cater to the different needs of these teams. Platforms like Courier focus on providing comprehensive notification infrastructure with features such as provider fallback routing, preference management, and extensive channel coverage, positioning themselves as suitable for developer and product-led teams. Others, like Iterable and OneSignal, offer user-friendly, no-code journey building tools ideal for marketing teams focusing on lifecycle campaigns and cross-channel orchestration. Braze targets B2C marketing teams with its robust analytics and segmentation capabilities, but with a higher price point. Meanwhile, open-source solutions like Novu offer customizable options for teams seeking more control over their infrastructure. The choice of platform depends on whether the emphasis is on campaign velocity or delivery reliability, with Courier standing out for its infrastructure-first approach and broad channel reach.
