Confirmation email cannot be sent
422 · confirmation_unavailable
Why you got this
This signup needs a confirmation email, because the list asks new members to confirm or the person unsubscribed or was deleted before. The account's from address is not on a verified sending domain, so that email cannot go out.
What to do
The account owner needs to verify a sending domain in Settings and set a from address on it, so pass this on to them. Safe to retry once it is done.
How it arrives
Every failure on the API is an RFC 7807 problem document, sent asapplication/problem+json. Branch on type — or on its last segment, which is the code above — rather than ontitle or detail, which are prose and may be reworded.
