Notifications are good for user experience. There, I said it. The word “notification” might conjure images of annoying interruptions for your users, but it should also remind them of moments where they were quietly guided to a more desirable experience. Notifications can guide users through key setup steps in onboarding, reward a positive interaction, and encourage exploration. They can stretch a product into an omnichannel experience and allow global brands to speak to each user as an individual. …


Almost every web application needs the functionality to send transactional emails in response to various triggers. Events like account registration, password resets, purchase receipts, and user verification are among the many tasks today’s applications need to accomplish via email. These emails are crucial for notifying users of important updates and enabling key user workflows in your application.

This post explores three different options for sending email from within a Node.js app. I’ll share each method’s pros and cons, so you can select the best method for your needs.

As a server-side tool, Node.js allows you to send emails using a…

Getting noticed on Product Hunt is a start-up founder’s dream, but it’s not an easy task. There’s only one chance at listing a specific domain, so it can’t be a short-sighted attempt. The internet is a web of communication, and depending on how it is used, teams can effectively notify their communities about their Product Hunt launch. We realized that the best route forward would be using a sophisticated notification strategy to increase timely engagement with the brand via the Product Hunt page. We were able to execute that strategy which helped us get noticed as we…


Did you know that email subjects, by default, only support 127 characters?! I didn’t, and I ran into a “fun” puzzle of a problem earlier this year when a client of ours noticed a problem with Courier-built emails in Microsoft Outlook. Small rendering issues and bugs like this can give the wrong impression to a recipient of an email. It can make the end user feel the product they are using is poorly planned or not tested. Not even just that, but not having support for certain characters can prevent you from reaching customers in other languages and countries.

Put simply, building and maintaining a completely custom notification system in-house is a pain. It requires a lot of human effort in the beginning and will undoubtedly need to scale at some point. Maintaining a system like this takes away development time from core tasks and business needs.

To make sure teams don’t need to build an in-house solution for a notification systems problem, we adapted our offering. We created a lightweight solution using React that has a global state and runs independently in the background — so teams can render our components regardless of their tech stack.

As a product engineer, you likely understand the value of incorporating notifications functionality into your Minimum Viable Product (MVP).

Here’s what you can accomplish by building notifications:

Drive engagement. Notifications inform customers that there’s something going on in your application that’s worthy of their attention. Timely notifying your audience about valuable content or interactions with other users is great for building trust and engagement.

Enable user journeys based on asynchronous actions.


Having been at startups my entire career, I’ve encountered the dichotomy between speed and scale when building software products. The usual attitude entrepreneurs take when building the first iterations of their products is “…we aren’t anywhere close to facing problems of scale, so let’s worry about that when we get there.” This first version of the software is built and shipped fast, and it’s only a matter of time before engineers realize that they simply don’t have the foundation to iterate quickly. Inevitably, limitations within their own infrastructure cause slow development cycles, impossible deadlines, and too much stress to maintain…


During the weekend of March 13th, 2021, we sponsored Hackabull, a 24-hour virtual hackathon hosted by the Society of Hispanic Professional Engineers at the University of South Florida. This was the first hackathon Courier has sponsored. We know that events are a great way to talk directly to developers and I am a huge advocate for the value a hackathon can bring to a company with a new developer-focused product. In all my years as a developer advocate and a software engineer before that, I learned how valuable hackathons can be for gathering real-time feedback and building community around your…


Some time back, our engineering leaders suddenly noticed dramatically increased billings from AWS that far outpaced typical benchmarks. The problem turned out to be data insights tools sending an unexpectedly large volume of data. The solution required a deep dive into how AWS billing works and an intricate series of steps to discover the location of the firehose of data. Courier’s Developer Advocate, Aydrian Howard, sat down with CTO Seth Carney to review and discuss the experience and how the team ultimately managed to control and reduce AWS costs.

Aydrian:

All right. Hello, Seth.

Seth:

Hey, Aydrian. How’s it going?

A pigeon looks decidedly at a GraphQL logo on a laptop computer with wild textures and colors.

When I Googled “what is GraphQL” to learn more about the network protocols, all I saw was a comparison between REST and GraphQL. Most of the conclusions said, “use GraphQL.” It felt very binary (and trendy, for that matter), which is a problem because each product and use-case is unique. The fact is, whatever is newest and shiniest gets recommended more loudly. But you have to weigh the trade-offs and come up with a solution that is best for your situation.

There is a general understanding that either REST is better than GraphQL or vice versa. But the truth is…
