Troubleshooting & FAQ Overview

When emails fail to deliver or land in spam folders, use MailFuz’s built-in diagnostics tools under MailFuz → Settings → System Status.

Quick Diagnostic Checklist

1. Verify Test Transmission: Send a test email from MailFuz → Send Email.
2. Review Email Logs: Inspect the response code and raw server response under MailFuz → Email Logs.
3. Run DNS Auditor: Check if SPF, DKIM, or DMARC are misconfigured or failing.
4. Test Port Connectivity: Verify port 587 or 465 is not blocked by your hosting firewall.
