Email Configuration controls the Resend credentials and sender identity PAX uses for outgoing email.
What this screen is for
Use Email Configuration to set up or update the tenant's outgoing email service. PAX uses this configuration for workflows that send email, including quote emails, invoice emails, work order emails, report emails, campaign sends, export-ready notifications, and test emails where those workflows are enabled.
Only admin and executive users see this setting in System Settings.

What happens behind the scenes
Saving Email Configuration creates or updates the tenant's email configuration record.
Test emails use the saved Resend API key and sender settings. PAX logs successful and failed test emails in email logs with the current user as sender.
Other modules read this same configuration when they send email. If the configuration is missing or invalid, email-capable workflows may fail even if the underlying business record is otherwise valid.
Troubleshooting
All fields are required
Likely cause: One or more email configuration fields are blank.
Safe fix: Complete Resend API Key, From Email, From Name, and Reply To, then save again.
Contact support if: All fields are populated but the save still fails.
Emails fail after saving configuration
Likely cause: The Resend API key, verified domain, DNS records, From Email, or Reply To setup may be invalid.
Safe fix: Use Show Setup Guide, confirm the domain is verified in Resend, save the configuration, and send a test email.
Contact support if: Resend is verified and test email still fails.
