Post SMTP – WordPress Plugin

Post SMTP is a WordPress plugin designed to improve email deliverability by replacing the default PHP mail function with authenticated SMTP services. It allows websites to send transactional emails through reliable mail providers such as Gmail, Microsoft 365, SendGrid, and Amazon SES. This approach ensures that outgoing emails reach inboxes instead of being flagged as spam.

The plugin includes a guided setup wizard that simplifies SMTP configuration using API-based authentication. This method removes the need to store sensitive credentials and improves overall email security. It supports multiple SMTP providers and enables quick integration through a structured interface.

Post SMTP also provides detailed monitoring tools for managing email performance. Users can access email logs, track delivery status, and receive alerts when failures occur. These features help diagnose issues and maintain consistent email communication across WordPress sites.

In addition, the plugin supports advanced capabilities such as backup SMTP connections, email tracking, and automated resend functionality. It also includes encryption features that secure email transmission and protect data from unauthorized access.

Post SMTP suits websites that require reliable email delivery, secure authentication, and detailed monitoring within a scalable WordPress environment.
