WP Mail SMTP Pro

Version: 4.5.0 | Last Updated: 05.06.2025 | License: GPL

WP Mail SMTP Pro is the industry-leading WordPress plugin specifically built to ensure reliable email delivery from your website. Email deliverability is one of the most common issues faced by WordPress site owners—whether you’re sending contact form notifications, purchase receipts, password reset emails, or newsletter updates. WordPress by default uses PHP mail, which often fails to deliver messages because of poor server configuration or being flagged as spam. WP Mail SMTP Pro solves this by reconfiguring the way your site sends emails, replacing the native wp_mail() function with trusted SMTP providers.

This plugin ensures your emails are authenticated and delivered using a real email server, improving the trustworthiness and deliverability of your messages. Whether you run a WooCommerce store, membership site, blog, or business website, WP Mail SMTP Pro offers the reliability and flexibility needed for professional communication.

Core Features

Secure Email Delivery with SMTP

WP Mail SMTP Pro allows you to connect your WordPress site with trusted SMTP services like Gmail, Outlook, SMTP.com, SendLayer, Amazon SES, Mailgun, SendGrid, and more. These services provide verified authentication using your domain name, preventing your emails from ending up in spam folders.

 Easy Setup Wizard

The setup wizard guides you through connecting your site with the email service of your choice. Even non-technical users can configure complex SMTP settings without touching a single line of code.

 Email Logging & Resending

Keep a full record of all emails sent from your WordPress site. The email log helps in diagnosing issues and proves delivery. You can even resend failed emails directly from the dashboard — a feature incredibly useful for missed form submissions or purchase confirmations.

 Smart Email Alerts

WP Mail SMTP Pro notifies you via your preferred email address if your site encounters delivery issues. These alerts help prevent unnoticed communication breakdowns with your users or customers.

 Weekly Email Reports

Get detailed insights into how many emails your site is sending, how many were delivered, failed, or sent to spam. These analytics help you identify trends and optimize performance.
