Pinny’s Simple SMTP

Pinny’s Simple SMTP is a ultra lightweight SMTP plugin weighing in at just 4KB. It’s simple to use, highly secure, and includes all the basic features you need to send emails reliably.

🚀 Super Easy 30-Second Configuration

Tired of bloated setup wizards, “Connect Account” popups, and endless menus?

Pinny’s Simple SMTP is designed to be invisible. We removed the fluff so you can get back to work.
1. Enter your Host & Port.
2. Enter your Login.
3. Click Save.

That’s it. You are done.
There is no complex UI to learn. No dashboards to manage. It is a true “Set and Forget” solution that just works.

Unlike most SMTP plugins (which are typically 2MB+ in size), Pinny’s Simple SMTP is ultra-lightweight, easy to set up, and never compromises on security. We ensure your sensitive credentials are always protected with automatic encryption—no more storing passwords in plain text.

This plugin is different. It’s smaller than a favicon, works with any mail provider, and takes just seconds to set up.

Features:

• Ultra Lightweight (4KB): This is the a ultra lightweight SMTP plugin. It has zero impact on your site speed.
• Encrypted Security: We take security seriously. Your SMTP password is encrypted in the database using native WordPress salts. We never store credentials in plain text.
• Dead Easy Setup: No confusing wizards or tutorials needed. Just enter your Host, Port, and Login, then click Save.
• All Basic Features: Supports TLS/SSL, custom ports, “From” email/name overrides, and includes a 1-Click Test Email tool.
• Zero Bloat: No ads, no dashboard widgets, no usage tracking, and no upsells.
• wp-config Configuration Mode: For added security, define SMTP settings in wp-config.php and lock the admin UI.

⚙️ Advanced: Configure SMTP via wp-config.php

Pinny’s Simple SMTP supports configuration directly from wp-config.php, allowing administrators and developers to lock SMTP settings and prevent changes from the WordPress dashboard.

When enabled, the plugin automatically switches the admin interface to read-only mode.

To enable this mode, add the following constants to your wp-config.php file

define('PINNYS_SMTP_FORCE', true);

define('PINNYS_SMTP_ENABLED', true);
define('PINNYS_SMTP_HOST', 'smtp.gmail.com');
define('PINNYS_SMTP_PORT', 587);
define('PINNYS_SMTP_ENCRYPTION', 'tls');

define('PINNYS_SMTP_AUTH', true);
define('PINNYS_SMTP_USERNAME', 'your@email.com');
define('PINNYS_SMTP_PASSWORD', 'your_app_password');

define('PINNYS_SMTP_FROM_EMAIL', 'your@email.com');
define('PINNYS_SMTP_FROM_NAME', 'Your Website');

Once PINNYS_SMTP_FORCE is enabled:

• SMTP settings are loaded from wp-config.php
• The WordPress settings page becomes read-only
• Dashboard changes cannot override your configuration
