It sits between your app and every channel you send on: email, SMS, push, in-app inbox, chat, and webhooks. You send one request, and Courier works out where it goes, what it looks like, and whether the user wanted it at all. Teams use it for the messages a product has to send: onboarding, alerts, receipts, reminders, and account notices. You keep the providers you already pay for. Courier is the layer above them. • Design a message once and it adapts to each channel it goes out on, whether you build it in the visual editor or manage it as code. • Journeys handle the sequencing: waits, batching, digests, and branching on what someone does or ignores. • Add an in-app inbox to your web and mobile apps without building one from scratch. • Users set their own channel and topic preferences, so you are not fielding requests to turn things off. • When a provider fails, Courier fails over to another, and every send lands in one log with its delivery status. Everything in the product is on the API, so the same template or journey works however your team wants to build it: in the visual editor, as code, or handed to an AI agent through Courier's MCP server. Courier connects to 50+ providers, including SendGrid, Amazon SES, Twilio, Firebase, and Slack, and bills per message sent at one rate on every channel, with no per-seat fees. The free tier covers 10,000 messages a month. Twilio, Trusted Health, and Nav run their customer messages on Courier. Founded in 2019 in San Francisco, Courier came out of Y Combinator and is backed by GV, Bessemer Venture Partners, Matrix Partners, Twilio, and Slack Fund. ## Courier Pros & Cons Pros and Cons are compiled from review feedback and grouped into themes to provide an easy-to-understand summary of user reviews. **What users like:** - Users value the **excellent customer support** of Courier, appreciating multiple contact methods for assistance with issues.
