A voice is a sender identity (a name, a role, and a tone) that Airdun uses when it writes recovery emails with the AI writer. You define a small set of voices for a use case; each time Airdun decides to send an email, it picks one of them and writes in that voice.
Voices are email-only, and only used by the AI writer. A text has no voice: Renewals and Free trials send Airdun’s short, fixed texts, chosen from the failure reason and the customer’s language, and New customers sends your own SMS template. When a use case runs on a Sequence, each of your email templates carries its own sender name and address, and no voice is used.

​
What a voice contains

There is no avatar or photo field: a voice carries identity and tone, not artwork.

​
How a voice is chosen

You do not map voices to emails by hand. Each time Airdun decides to send an email on a case, it picks one of the use case’s voices for that email, based on each voice’s name, role, and tone, and on which one is primary. A warmer founder voice might carry a softer ask; a billing voice a firmer notice. You steer the outcome three ways:
  • Which voices exist: Airdun can only choose from the voices you have created.
  • Each voice’s tone text: your main lever; it is what the model reads to decide fit and how to write.
  • Which voice is primary: the default when nothing else fits.
The From name and address are fixed when Airdun decides to send, and the email is written right away, so a later edit to a voice does not change an email that is already scheduled.

​
Voices vs. sending domains

  • A sending domain is your workspace’s authenticated email identity: the domain, with its DNS records verified. It is set up once, under Channels → Email, and is what makes email deliverable.
  • A voice is a persona. Its optional sending address must sit on an already-verified domain; if you leave it empty, the workspace default sender is used.

​
Managing voices

Voices belong to a use case: Renewals and Free trials each have their own (New customers has no AI writer). In your Airdun dashboard, go to Autopilot → [use case] → Messages → AI writer voices. From there you can create, edit, and delete that use case’s voices, and set which one is primary. Adding at least one voice is required before switching a use case to the AI writer. Creating, editing, and deleting voices, and changing the primary, are restricted to admins and owners.
You cannot un-set the current primary directly: promote another voice to primary and the previous one steps down. Deleting a voice cancels any pending emails still assigned to it, and, if you deleted the primary, the oldest remaining voice of the use case becomes primary.
Create at least two voices with clearly different tones (for example a warm relationship voice and a firmer billing voice). With only one voice, every email the AI writer sends for that use case speaks the same way.
