Channels are set up in two places.
  • Channels in the sidebar (the Channels configuration page), once for your workspace: the sending domain, the SMS sender name, the WhatsApp number, the in-app wall script. Every use case shares them.
  • Each use case’s page under Autopilot: which of those channels Renewals, Free trials, or New customers actually uses. A channel can be on for one use case and off for another.
1

Email

Open Channels configuration → Email. Add your sending domain and the DNS records Airdun shows (DKIM and Return-Path, plus SPF and DMARC when listed), and set a reply-to address. The default sender set here is used whenever a template or a voice doesn’t set its own.
A verified sending domain with a reply-to address is a required workspace step of the setup checklist. See Brand Voice.
2

SMS

Open Channels configuration → SMS. Set the brand name your texts are sent under, then confirm that your customers consented to receive texts. See SMS.
3

WhatsApp

Once WhatsApp is available on your account, open Channels configuration → WhatsApp and connect a WhatsApp Business number. Meta registers the number and reviews the message templates; Airdun only uses approved ones.
4

In-app wall

Open Channels configuration → In-app wall and add the script to your app. One install serves every use case. Installing it is a recommended workspace step of the setup checklist, done as soon as Airdun sees the script on your site. See In-App Wall.

Turn channels on per use case

On each use case’s page under Autopilot, turn on the channels it should use. A channel that is not connected yet shows what is missing.

Stripe’s retry settings

Your Stripe retry policy (number of retries and window) is confirmed under Business context → Stripe. It describes what Stripe does; Stripe still runs those retries. Airdun uses it to time its outreach around them. Confirming it is a required workspace step of the setup checklist. See Smart Retries.
