Keep your Stripe revenue flowing.

Stunning stops SaaS app churn by ensuring that billing information is always current.

Our customers have rescued $23,729,170 in recurring revenue by using Stunning.

You've recently signed up for Stripe to power subscriptions for your SaaS app. As a developer, it's the best API you've ever seen for payments, and getting started was a breeze. It's given you a ton of flexibility, because you can build payments into your app in whatever way you'd like, customizing it in just about any way that you can think up.

The problem is: You've been writing your app for weeks, or even months. You've added the code to accept payments, and you've got paying customers. But you just got a sinking feeling. What happens when you have trouble charging those customers? When their credit card expires, or when they cancel the card but forget to update their billing information, how do you make sure that you keep getting paid?

Your business is built on recurring revenue. Make sure that it keeps recurring.

You've worked hard to get customers, and you want to make sure that they stay customers. You don't want to lose them due to expired cards, but you just want to get back to writing code for your app. You know that you need dunning in your app (code that sends notifications over time when billing issues arise and allows customers to update their billing information), but the thought of figuring out what webhooks to listen for, how to respond to them, and making sure it's all tested and stable is just not something that you want to deal with or worry about.

Your dreams = reality. No code required.

What if you didn't have to worry about lost revenue due to expired cards and failed payments, and you didn't have to write a single line of code to make that a reality? Stunning makes that possible.

So how does it work?

You connect Stunning securely to your Stripe account, using Stripe Connect.
Stunning listens to your Stripe account for important events.
When a customer can't be charged, Stunning sends a series of emails to your customers on your behalf, and optionally notifies you as well.

But you don't have to take our word for it!

Here's what some of our customers have to say about Stunning.

"We use Stunning to send detailed receipts, emails about credit card status, and our favorite, personalized welcome emails. I love being able to send customized emails automatically based on actions that my customers have taken. This has cut our manual workload in half! I would recommend Stunning not only because the product is great, but also because the company building it is focused on our success. They are responsive, they are smart, and they offer a great product!"

— Blakely Graham,

"Customer churn is one of the key metrics that we watch very closely here at FullContact. Stunning allowed us to focus on building our product while quickly implementing, without any code, a solution that allows us to send receipts, cancellation, and dunning emails to our customers."

— Travis Todd,

So what does Stunning include?


Stunning will send an email to your customer 10 days before their credit card expiration date, so that they can update their billing information before a payment fails. This keeps your cash-flow on track, because you end up with less failed payments.


When a card is unable to be charged for any reason, Stunning emails your customer and lets them know what the issue is so that they can fix it and keep their subscription active. It can also send emails for many other Stripe events.

Customizable Receipts

Easily send your customers fully customizable plain-text or HTML receipts each time they are charged. Use your own templates, for consistent branding.

Payment Update Pages

Stunning provides optional, secure, white-label payment update pages that you can link to in your dunning emails, so that your users can easily update their payment info. You can also use our payment pages on your own domain, or you can link to your own!


Conditions allow you to have specific emails sent only to customers who meet certain criteria. Combined with the ability to have multiple templates, this allows you a ton of flexibility.
