Use this workflow to confirm that the saved Email Configuration can send through Resend.
When to use this workflow
Send a test email after first configuring email, after changing Resend credentials, after changing the sender address, or when email workflows fail.
Before you start
You need:
adminorexecutiveaccess.- A saved Email Configuration.
- One or more recipient email addresses for testing.
The test form accepts multiple recipients separated by commas or semicolons. The maximum is 50 recipients.
Screen path
Dashboard > System Settings > Communications > Email Configuration > Send Test Email
Steps
- Open
System Settings. - In
Communications, selectEmail Configuration. - Confirm the email configuration is saved and you are not in edit mode.
- In
Test Email Address(es), enter one or more email addresses. - Select
Send Test Email. - Wait for the success or error message.
- Confirm the test message arrives in the recipient inbox.
What happens behind the scenes
PAX validates the recipient list before sending. Empty, invalid, or over-limit recipient lists are rejected before the test send.
PAX sends the message through Resend using the saved Resend API Key, From Email, From Name, and Reply To. The subject is PAX ERP - Test Email.
PAX records successful and failed test sends in email logs. Failed sends include the returned error message where available.
Troubleshooting
Please enter at least one valid test email address
Likely cause: The field is blank or does not contain a valid email address.
Safe fix: Enter a valid address such as person@example.com.
Contact support if: A clearly valid address is rejected.
Maximum 50 recipients allowed
Likely cause: The recipient list contains more than 50 parsed email addresses.
Safe fix: Send the test to fewer recipients.
Contact support if: The count appears wrong after removing extra addresses.
Please save your email configuration before sending a test
Likely cause: No saved Resend API key is available.
Safe fix: Save Email Configuration first, then send the test email.
Contact support if: The configuration is saved but PAX still reports it missing.
Failed to send test email
Likely cause: Resend rejected the request, the API key is invalid, the sender domain is not verified, or the recipient could not be accepted.
Safe fix: Review the error message, verify Resend setup, and retry with one known-good recipient.
Contact support if: Resend setup is verified but test sends continue to fail.
