How to test email delivery and understand the result
Titanium uses a real test email instead of a separate credential-only connection check. This tests the actual WordPress sending path, provider authentication and message delivery request together. Free can send the test through either the Primary Connection or its one Additional Connection.
A useful testing order
- Open Titanium Mail SMTP → Tools → Test Email.
- Select the Primary Connection or Additional Connection you want to test.
- Enter a recipient address you can check and press Send Test Email once. The button becomes inactive and shows a spinner while WordPress is working.
- Read the complete result shown by Titanium. Missing credentials, authentication errors and provider responses are reported by the real send attempt.
- Check the inbox, spam folder and the provider activity log.
- On Local, check Mailpit or MailHog because local email is often captured instead of sent to the internet.
