When we were building our SaaS app notifications were on top of our minds to increase usage and adoption. However, as a bootstrapped startup, then, we did not have the bandwidth to create notification infra. Courier's superb platform made it a <1 day job for one of our devs to set up all aspects of notifications for our app. On top of that, you get the pay-as-you-go pricing and the very generous developer plan to get things right.

When we started using courier, there were a few features missing from the platform, notably sending the same notification to multiple people. However, Courier has added that feature now and have also committed to adding the notification preferences feature we have been looking for. Review collected by and hosted on G2.com.

What we like the most about Courier is keeping track of the emails that were sent, and seeing how they were rendered. Great for quality control. In addition, the template engine with multi-language support is great. The design of the emails can be done then by a dedicated team, shifting the burden away from the dev team.

You lose fine-grained control of the design of the templates. But, looking back, it is not a bad thing as delivering rich emails that are correctly displayed by all email clients is a tricky thing. Review collected by and hosted on G2.com.

The face that it's the onestop place to manage all your notifications which can be tricky. The log traces of previous sends you've done. One stop integation of third parties. Review collected by and hosted on G2.com.

Application performance is slow. Unsubscribe is not easy to set up so we've used what sendgrid provides. It would be a great idea if email from and adress from could be setup in courier. Review collected by and hosted on G2.com.

The markdown language for writing templates is great.

I also like the UX in general, the easy way to select email vendors and the simplicity of sending test emails. Review collected by and hosted on G2.com.

I think the most challenging issue with Courier is its poor SEO.

Trying to find resources regarding its API, documentation, and community threads is impossible via the web. Review collected by and hosted on G2.com.

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'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.

For me, what I like the most about Courier is that I can seamlessly track the emails that were sent. For an early-stage startup like us that is starting to scale, Courier has really helped us in terms of quality control. Another thing that I love about Courier is its simplicity of use. I am a stickler for templates and Courier makes it super easy to customize them and at the same time ensures that the engineering teams get to spend their bandwidth on core development.

As a non-technical person (I am the co-founder of Klaar <www.klaarhq.com> and look after Growth, BD, and a few other things), I had a bit of a learning curve to get used to Courier. It could be more user-friendly for non-technical folks but once I got used to it, it was seamless. Also, I am guessing non-technical people like me aren't really their target market, so I understand.

I really enjoy Courier and how easy it makes sending notifications to end users using an interactive UI or a detailed API Review collected by and hosted on G2.com.

Reporting could be improved. If errors occur on a notification, it would be helpful if that could trigger a notification to a slack channel or email so that end users are notified when a notification is breaking Review collected by and hosted on G2.com.

The platform's design and the all-powerful email editor make it easy to add logic to notification content. I especially like the handlebars feature which allows me to write code within it. Review collected by and hosted on G2.com.

The Platform is a little slow and does not handle lower internet speeds well. Review collected by and hosted on G2.com.

Courier has added a ton of integrations over the last couple of years, and the workflow feature is making them a serious alternative to event-driven automation platforms like Zapier, and IFTT. I really appreciate the near real-time performance, and the super detailed logs and state tracking that makes debugging and monitoring really easy. Review collected by and hosted on G2.com.

Their WYSIWIG templates are very limited in design options, so it's either live with that, or go it alone with raw HTML which is full of pitfalls for emails. Review collected by and hosted on G2.com.

The ease of creating email templates, with a nice rich text editing experience, and drag and drop interface for buttons and different sections. What you see is what you get. Review collected by and hosted on G2.com.

It's not immediately obvious where you can add the variables coming in from the API. Adding variables in links and button CTAs is not too intuitive. Having a list of these variables while editing would be useful. Review collected by and hosted on G2.com.
