What your customers see during recovery, and what governs it.
Emails come from your verified domain, texts from your brand name, and WhatsApp messages from your WhatsApp Business number; the in-app wall runs inside your app. Recovery messages are sent under your names, not Airdun’s.
  • Built-in limits: Airdun caps how often a customer is contacted and spaces messages out. New customers get one email, then one text the same day if the invoice is still unpaid.
  • Sending hours: messages go out during daytime hours in the customer’s time zone, and only on workdays if you set it.
  • Auto-stop: messaging ends when the invoice is paid. No message is sent after the issue is resolved.
  • Other stops: messaging also stops when the case is escalated to your team, when you pause or stop it, or when the invoice is voided or written off.
Each message:
  • Comes from your email domain or your SMS brand name
  • Says the payment did not go through, without naming a reason that could embarrass the customer
  • Includes a link to the invoice’s Stripe payment page
With the AI writer, each email is written for the case, in the voice Airdun picked. With a sequence, Airdun sends your templates, filling in only the AI variables you added.
Each message links to the invoice’s Stripe payment page, with your Stripe branding. The customer does not log in:
  1. Clicks the link
  2. Sees the invoice and the amount due
  3. Pays with a new card or another method
  4. The card is saved as the subscription’s default for future renewals
  5. Once Stripe confirms the payment, the case closes and no further messages are sent
If the in-app wall is on for the use case, customers with an open Renewals or Free trials case see an overlay when they open your application, with your wall message and a button to the Stripe hosted invoice. By default the customer can close it and keep using the app; it reappears after a short cooldown while the payment is still outstanding, and stops for good once it is recovered. If you enable hard lock, the overlay stops being dismissible after a delay you choose and blocks the app until the payment is fixed.The wall is not shown on New customers cases, nor on payments Stripe blocked as suspected fraud. See In-App Wall.
Yes. When Stripe confirms the payment, Airdun closes the case and cancels every pending message and retry, and the wall stops showing. Nothing needs to be closed manually.
Messages are written in the customer’s language when it is English, French, Spanish, German, Italian, Portuguese, or Dutch (otherwise in the fallback language you set), and sent during daytime hours in the customer’s time zone, worked out from their phone or billing country.
