Getting Airdun running takes four steps and no engineering work: create an account, connect Stripe when prompted, turn off Stripe’s own dunning emails, configure your channels, and switch on the autopilot.
1

Create Your Account and Connect Stripe

Go to app.airdun.com/register and sign up with your work email. No credit card is required.In the onboarding flow, click Connect Stripe when prompted. You will be redirected to Stripe’s standard OAuth consent screen, where you grant Airdun access to your account — no API keys, no manual configuration.That access powers your payment audit: Airdun reads your payment history, calculates your recoverable MRR, and recommends a plan tier for your volume. Airdun does not retry or charge payments — Stripe does that under your own retry policy. The one write Airdun performs is setting a newly entered card as a subscription’s default payment method, so future renewals use it. See Data Access.

Disable Stripe's Dunning Emails

Before going live, turn off Stripe’s automatic dunning emails in your Stripe Dashboard under Settings → Billing → Subscriptions and emails. Airdun sends its own recovery messages from your domain; leaving Stripe’s emails on means your customers receive two separate messages about the same failed payment.
Disable the emails only. Leave Stripe’s Smart Retries enabled — they do not conflict with Airdun.
3

Configure Your Autopilot

In your Airdun dashboard, enable the channels you want recovery to use:
  • Email — verify your sending domain (SPF and DKIM) and create at least one voice to send recovery emails from your own address.
  • SMS — Airdun provisions a phone number on your behalf.
  • In-App Payment Wall — requires the Airdun snippet installed in your application.
See Channels Setup for the full procedure for each channel.

Switch On the Autopilot

Toggle Autopilot to on. Airdun begins monitoring your Stripe account for new payment failures. Each failure opens a recovery case: Airdun enriches it with failure context and customer data, designs a sequence across your enabled channels, and executes it.
Airdun stops the recovery sequence for a case the instant the payment succeeds. There is no risk of chasing a payment that has already been resolved.
