Product Description
WP Mail SMTP Pro addresses the common WordPress email delivery problem — messages sent through the default PHP mail function often end up in spam folders or fail to deliver entirely. The plugin routes WordPress emails through authenticated channels that improve deliverability and provide sending visibility.
Email Delivery Problem
WordPress uses PHP's mail function by default, which sends email without authentication. Many hosting providers restrict this function, and receiving servers frequently flag unauthenticated messages as spam. WP Mail SMTP replaces this mechanism with authenticated sending through configured mailers.
Supported Mailers
- Transactional services — SendLayer, SMTP.com, Brevo (Sendinblue), Mailgun, Postmark, SparkPost
- Cloud providers — Amazon SES, Google Workspace / Gmail API, Microsoft 365 / Outlook API
- Custom SMTP — any SMTP server with configurable host, port, and authentication settings
- Backup connections — configure fallback mailers that activate when the primary connection fails
Email Logging
The Pro version logs all emails sent from WordPress with delivery status, recipient details, subject lines, and timestamps. This log helps troubleshoot delivery issues and provides an audit trail of all outgoing communications.
Open & Click Tracking
Track which recipients open emails and click links within them. These metrics provide insight into email engagement beyond simple delivery confirmation, helping identify whether emails reach inboxes effectively.
Deliverability Tools
DNS verification checks confirm that SPF, DKIM, and DMARC records are properly configured for your sending domain. These authentication protocols are critical for email deliverability, and the plugin identifies missing or misconfigured records.
