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 read-only access to your account — no API keys, no manual configuration.That read-only access powers your payment audit: it scans your payment history, calculates your recoverable MRR, and recommends a plan tier for your volume. Your Stripe data is not modified at this stage. The only write action Airdun ever takes on your Stripe account is retrying a payment as part of an active recovery plan.

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.

Configure Your Autopilot

In your Airdun dashboard, enable the channels you want recovery to use:
  • Email — connect your sending domain to deliver recovery emails from your own address. Requires at least one sender persona with verified SPF/DKIM records.
  • SMS — Airdun provisions a phone number on your behalf.
  • WhatsApp — Airdun manages the WhatsApp Business API setup.
  • 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.
