What is WP SMTP Mailer?

WP SMTP Mailer – SMTP7 is a dedicated plugin that reroutes your WordPress site’s outgoing emails through a SMTP server. This process, similar to how a postman delivers mail, ensures your messages land in the inbox rather than the spam folder. Developed by Arshid, the plugin has been available for 10 years, accumulating 9K+ active installs. It holds a 5.0/5 rating from 112 reviews, with 98% of those being five-star ratings and zero one-star ratings. The current version is 1.1.0 and it was last updated on May 20, 2026.

If you have ever struggled with how to send email from WordPress using SMTP, this plugin provides a direct solution. It replaces the default PHP mail function with a authenticated SMTP connection. This approach is critical for transactional emails like password resets and order confirmations.

Who Should Use WP SMTP Mailer?

This plugin is built for WordPress site owners who need a straightforward way to configure SMTP in WordPress without complex setup. It suits beginners and intermediate users who manage small to medium websites, such as blogs, business sites, or e-commerce stores. With 9K+ active installs, it appeals to those who prefer a lightweight tool over all-in-one email suites.

The ideal user has a SMTP server ready—like Gmail or Outlook—and wants to fix WordPress email not sending SMTP errors. The plugin’s 10-year history and 98% five-star rating indicate it reliably solves this single problem. It is not designed for high-volume transactional email services but works well for standard WordPress notifications.

Installation & Setup

Installation follows the standard WordPress plugin process: download, extract to the wp-content/plugins directory, and activate from the admin panel. After activation, navigate to Settings > SMTP7 to enter your wp mail smtp settings. The interface is minimal and beginner-friendly, requiring only your SMTP host, port, and credentials. No advanced coding or server modifications are needed.

Support & Community

Support data shows a mixed picture. In the last two months, the plugin had 1 open support thread and 0 resolved threads, resulting in a 0% resolution rate. This contrasts sharply with the user ratings, where 98% of 112 reviews are five stars. The developer provides a contact page at ciphercoin.com for direct inquiries. The high rating suggests that most users find the plugin works out of the box, but the support threads indicate limited active troubleshooting for edge cases. The plugin requires WordPress 3.5+ and PHP 5.6+, making it compatible with older installations.
