Courier is notification infrastructure for customer messaging, built for humans and AI agents. 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. * * * Seller [Courier](https://www.g2.com/sellers/courier) Discussions [Courier Community](https://www.g2.com/products/courier/discuss) Languages Supported English Solution Type All-in-One Overview by Thomas Schiavone (CEO @ Courier) Show More ## Pricing Pricing provided by Courier. ### Developer $0.00 ### Pro Pay As You Go [ View More Pricing Information ](https://www.g2.com/products/courier/pricing) ## Top-Rated Alternatives [ ![Knock](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Knock") Knock 4.6/5(147) ](https://www.g2.com/products/knock-knock/reviews) [ ![OneSignal](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "OneSignal") OneSignal 4.7/5(1,228) ](https://www.g2.com/products/onesignal/reviews) [ ![Twilio SendGrid Email API](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Twilio SendGrid Email API") Twilio SendGrid Email API 4/5(368) ](https://www.g2.com/products/twilio-sendgrid-email-api/reviews) [ View All Alternatives ](https://www.g2.com/products/courier/competitors/alternatives) ## User Insights Average based on 59 real user reviews.

The fact that you can switch email providers easily allows us to prevent vendor lock-in as we scale. The sheer number of providers makes me confident I can use just about any service I think is suitable. The designer is simple to use and flexible when it works. The fact that product folks are able to tweak email designs without involving engineering is a huge productivity win. It looks like there are many other channel capabilities besides email that we could look to use in engaging our customers. Review collected by and hosted on G2.com. What do you dislike about Courier? The web editor has about a 70% chance of working at any given moment. (I normally use Edge, but seems more consistent on Chrome?). When it doesn't work, the page seems to get stuck loading (some content loads, but the loading indicator continues to flash). It happens frequently enough that it can be painful to get work done on something that Courier otherwise makes very easy to accomplish. Review collected by and hosted on G2.com. What problems is Courier solving and how is that benefiting you? We use it for sending emails to customers about any updates related to their accounts. It frees up engineers from the design/format aspect of messaging, but at the same time makes it very easy for engineers to integrate data. It is preventing us from needing to commit to something like AWS SES and invest time/effort into setting up a custom integration and allows us to pivot between providers if needed.

Thank you for the feedback on the performance of our UI in the MS Edge browser. If you see this behavior again, please email me Nate@ or support@courier.com so we can investigate formally. In the meantime, our Support Engineer is doing some investigation of Courier and Edge to see if we can identify any compatibility issues ourselves. We appreciate you taking the time to share your thoughts on Courier with the world 🙏.

What I like about Courier is that's it relatively easy to set up and get started. You connect x email provider, drop their inbox application into yours, create a message and you're good. The uptime and message delivery has not been a problem, and they have nice ways of styling and mainting your notification messages. Review collected by and hosted on G2.com. What do you dislike about Courier? What's bothered me about Courier is that they've fallen short in terms of things they've promised vs their delivery. I get it, they're a relatively young company, but at the same time things like notification preferences are very clearly advertised on their home page, yet the UI for it still doesn't exist, and we've had to rig our own just to work with theirs. Furthermore, I've experienced several bugs with their notification inbox, and while the support team has been very responsive, I can't help but feel like these are things that shouldn't be neglected, considering it's one of their main value propositions. This is a company that I want to do better though, and I think they will. Review collected by and hosted on G2.com. What problems is Courier solving and how is that benefiting you? They're helping me not have to make my own notification system from scratch. Although their are several pieces I've had to make on my own still, this has helped.
