Select Email Logs from the WP Postman submenu. The full log table loads immediately, sorted by most recent first.
Understanding the Log Table
Each row in the log table represents a single outbound email attempt. The columns are:Viewing a Log Entry
1
Locate the entry you want to inspect
Find the message in the log table by scanning the Recipient or Subject columns, or use your browser’s find-in-page to search for a specific address.
2
Click the View button
Click the View button in the Action column for that row. A detail panel opens.
3
Review the message details
The detail panel shows the complete email headers (From, To, CC, Reply-To), the full HTML or plain-text message body, and — for failed messages — the error response returned by the SMTP server. Copy this error text when contacting your SMTP provider’s support team.
Diagnosing Failed Emails
When a log entry shows a Failed status, the error message in the detail panel points to the root cause. Use the accordion below to match the error to a fix.Authentication failed
Authentication failed
The SMTP server rejected your username or password. Double-check both fields in WP Postman → SMTP Settings. If you are using Gmail, remember that your regular Google account password does not work here — you must generate and use a dedicated App Password with 2FA enabled on your Google account. For other providers, verify that the credential you are using has not been rotated or revoked in your provider’s dashboard.
Connection refused
Connection refused
WP Postman could not establish a TCP connection to the SMTP host. Confirm the hostname is spelled correctly and that the port number matches the encryption setting you have chosen (587 for TLS, 465 for SSL). On some network configurations a firewall rule on the server blocks outbound SMTP connections — if you suspect this, contact WP Stratos support to confirm whether outbound connections on your chosen port are permitted.
TLS handshake error
TLS handshake error
The server connected but failed to negotiate a secure channel. This usually means there is a mismatch between the encryption setting in WP Postman and what the remote server expects. Try switching the Encryption setting between TLS and SSL, or temporarily set it to None to isolate whether the issue is with the encryption negotiation itself. Re-enable encryption once the connection is confirmed working.
Recipient rejected
Recipient rejected
Your SMTP server accepted the message and attempted delivery, but the recipient’s mail server refused it. This is outside WP Postman’s control and is typically caused by the recipient’s domain having strict spam filters, a full mailbox, or a policy that blocks messages from your sending domain. Check that your From Email address is on a domain with valid SPF, DKIM, and DMARC records published in DNS. Your SMTP provider’s dashboard may show additional bounce details.
Email logs are retained for 30 days and then automatically deleted. If you need to keep a longer-term record of email activity, export or copy relevant log entries before they age out.
