Pinny's Simple SMTP – The Lightest SMTP Plugin (4KB) & Dead Easy Setup

Pinny’s Simple SMTP is the lightest SMTP plugin in the entire WordPress repository, weighing in at just 4.5KB. It’s simple to use, highly secure, and includes all the basic features you need to send emails reliably.

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:

• World’s Lightest (4.5KB): This is the most lightweight SMTP plugin currently available on the repository. 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.
