What happens behind the scenes
PAX validates that all four fields are present before saving. The configuration is stored for the tenant and reused by PAX email workflows.
The setup guide points users to Resend domain setup, DNS records, domain verification, API key creation, and a test send. PAX does not verify DNS directly on this screen; the real confirmation is a successful send through Resend.
Troubleshooting
Save Configuration is blocked
Likely cause: One or more required fields are blank.
Safe fix: Complete every field and save again.
Contact support if: Required fields are complete but the save fails.
The test email fails after saving
Likely cause: Resend rejected the API key, sender domain, recipient, or account setup.
Safe fix: Confirm the domain is verified in Resend and the From Email uses that verified domain.
Contact support if: Resend shows the domain and API key are valid but PAX still cannot send.
