Courier
Notification infrastructure with visual journeys.
Courier blends notification infrastructure with marketing-style journeys. Visual template builder, drop-in inbox UI, native Slack and Teams routing. Bridges product notifications and customer engagement.
A SaaS product sends on behalf of its customers, so the deciding factors are tenant isolation, whether suppressions can be scoped rather than global, and whether support can answer why one specific account did not receive one specific email. Lifecycle automation and transactional sending usually need to coexist.
Against trial expiry notices, dunning, onboarding sequences, and per-tenant transactional mail, Courier covers multi-tenant support, event stream, the suppressions API, scheduling, and webhook coverage, and does not cover operating track record. Whether that gap matters depends on how central those are to the build.
