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.
At an early stage the deciding factors are what the free tier actually covers, what the first paid invoice looks like, and how much of a founding engineer's week the setup costs. Feature depth that only matters at a million sends a month is noise until it is not.
Against a waitlist, a launch announcement, onboarding email, and the first transactional sends, Courier covers developer experience, scheduling, SDK breadth, and webhook coverage, and does not cover operating track record. Whether that gap matters depends on how central those are to the build.
