What Is It?
Simplified SMTP Mail is a lightweight WordPress plugin that configures the built-in PHPMailer to use a custom SMTP server for sending all emails. It's lightweight, secure, and works seamlessly with all plugins and themes using wp_mail().
Why use SMTP instead of your host’s mail function?
- ✔️ Higher deliverability — avoid spam folders
- ✔️ Full support for SPF, DKIM, and DMARC
- ✔️ Authenticate with a real SMTP account (e.g., your domain email)
- ✔️ No dependency on your host's PHP
mail() function
- ✔️ Works with WooCommerce, contact forms, password resets and more
Features
- Uses WordPress’s internal PHPMailer – no external libraries required
- Fully compatible with all plugins/themes that rely on
wp_mail()
- Simple admin interface with test email support
- SMTP authentication and encryption (SSL/TLS)
- Lightweight and no bloat
Requirements
- WordPress 5.0 or newer
- A valid SMTP account (e.g., Mailgun, Gmail, or your hosting provider)
Installation
- Install via Plugins → Add New in your WordPress admin and search for
Simplified SMTP Mail (once listed on WordPress.org)
- Or download it directly from GitHub and upload it to your
/wp-content/plugins/ directory
- Activate via WordPress admin plugins menu page
- Go to SMTP Mail in your admin menu and configure your settings
- Note: It's important to click 'Save Changes' before using the 'Send Test Email' button. This ensures that the system is configured with the new correct parameters before testing whether everything works correctly. The test doesn't just verify the new settings but evaluates the entire system, including the updated configuration, to ensure maximum compatibility. :-)
