Troubleshooting Workflow Emails Blocked by Email Server
Symptom/Error
You'll experience these symptoms:
Workflows are triggering and showing as successful in the system
Email logs show 'Rejected' status for certain recipient addresses
Recipients report they are not receiving expected workflow emails
The workflow itself appears to be functioning properly
Cause
This occurs when Dazos's email service provider has temporarily flagged the recipient address due to previous delivery failures. The email server blocks messages sent to these addresses, causing them to be rejected even though the workflow executes correctly.
Solution
Follow these steps to resolve the email blocking issue:
Identify the blocked address: Check your workflow logs to confirm which specific email address is showing 'Rejected' status
Contact Dazos Support: Report the blocked email address to our support team
Request whitelisting: Our team will whitelist the blocked address in the Dazos system
Test delivery: After whitelisting, test the workflow with a sample record to confirm emails are now being delivered successfully
Monitor logs: Check that the email status has changed from 'Rejected' to 'Delivered' in your workflow logs
Verification
After the address has been whitelisted, you should see:
Email status showing as 'Delivered' in workflow logs
Recipients confirming they are receiving the workflow emails
No more 'Rejected' statuses for the previously blocked address
💡 Tip: Once an address is whitelisted, it should continue to receive emails without issues going forward.
When to Contact Support
Contact Dazos Support immediately if:
You identify workflow emails showing 'Rejected' status in logs
Recipients report that they stopped receiving workflow emails suddenly
Multiple email addresses appear to be blocked
The issue persists after whitelisting
When contacting support, provide:
The specific email addresses that are blocked
Examples of affected workflows
Screenshots of workflow logs showing 'Rejected' status
