常见问题:
Does Titanium Mail SMTP replace wp_mail()?
It works with WordPress wp_mail() and routes supported messages through the selected connection. Existing plugins and themes can continue using the normal WordPress mail function.
How does Free Smart Routing work?
Each route can contain several AND conditions. Additional groups are evaluated with OR logic. The first matching route sends through the Additional Connection. If no route matches, the message uses the Primary Connection.
Is the Additional Connection a backup connection?
No. In Free it is a normal routing target. Automatic backup delivery, failover, background delivery, and retry are Pro features.
What permissions do Gmail and Microsoft OAuth request?
Google OAuth requests only the Gmail send scope https://www.googleapis.com/auth/gmail.send. Microsoft OAuth requests delegated Mail.Send, Mail.ReadWrite, and offline_access. Titanium uses Mail.ReadWrite only to create a temporary outgoing draft and add attachments when Microsoft Graph delivery needs the draft/upload-session path; it does not intentionally read existing mailbox messages. OAuth access and refresh tokens are stored locally in WordPress and are cleared when the matching OAuth application identity is changed.
What is Return Path?
Return Path is the envelope sender used by WordPress default mail and Other SMTP. Leave it empty to preserve the existing behavior. Developers can override it for an individual email with the tmsmtp_return_path filter. Gmail and Microsoft API delivery use provider-managed envelope behavior rather than pretending to support an override their APIs do not expose in the same way.
What happens when no external provider is configured?
The plugin keeps WordPress default mail available, so an incomplete or new installation does not block normal website email.
Does the plugin send email data before a provider is configured?
No. Email content and provider credentials are sent to an external email service only after an administrator selects and configures that provider and WordPress sends an email, including a test email requested by an administrator. OAuth authorization starts only after an administrator explicitly clicks Connect.
Does Free store a complete email log?
No. The Free version does not include the Full Email Log and does not intentionally keep a persistent copy of complete sent email content after delivery. WordPress, the selected email provider, the hosting environment, or another installed plugin may still process or store email according to its own configuration.
Does the WP Mail SMTP importer delete the original settings?
No. It can import a supported primary connection once, but it does not change or delete the original WP Mail SMTP settings.
Does opening the Upgrade page contact AdminPlugins automatically?
No. Current prices are disabled by default. They are loaded only after an administrator explicitly enables current price display, and price loading can be disabled again from the same Upgrade page. The Upgrade Now buttons continue to open Freemius checkout while prices are hidden.
Can I skip the Freemius connection in Free?
Yes. The Freemius opt-in screen can be skipped, and the Free email delivery and routing features remain available.
