WP Mail Options

WP Mail Options (or WP Mail SMTP) is a plugin that configures WordPress to send emails through a proper SMTP server instead of the default PHP mail function.

Overview

WordPress uses PHP's mail() function by default, which often results in emails being marked as spam or not being delivered. WP Mail SMTP fixes this by routing emails through proper SMTP servers like Gmail, SendGrid, or your hosting provider's SMTP service.

Key Features

• SMTP Configuration - Send emails via SMTP servers
• Multiple Providers - Support for Gmail, Outlook, SendGrid, etc.
• Email Logging - Track sent emails
• Email Testing - Test email delivery
• Security - Secure email authentication
• Delivery Reports - Monitor email delivery status
