Simple SMTP

63 Quality Score

Active Installs

15/30

With only 2,000 active installs, adoption is very low compared to WP Mail SMTP at 4 million, so the plugin remains niche.

Update Freshness

15/25

Last updated August 2025 and tested against WordPress 6.8.5, so maintenance is current, though the solo-developer pattern limits long-term confidence.

User Rating

15/15

All 11 reviewers gave 5 stars, producing a perfect 100 score, but the tiny sample size makes this rating far less meaningful than a plugin with thousands of reviews.

Support Health

8/15

Only 2 support threads exist and neither has been resolved, which is a red flag for anyone who may need help configuring SMTP issues.

WP Compatibility

11/15

Rated for WordPress 5.0 and PHP 7.0 minimum and tested with the latest 6.8.5 release, so compatibility is broad but there is no verified multi-version matrix.

What It Does

Simple SMTP adds a basic mail configuration panel to your WordPress admin, letting you set SMTP credentials so outgoing emails route through a proper mail server instead of default PHP mail(). It also supports temporary logging to troubleshoot delivery and stores config values for reuse. In short, it is a lightweight, no-frills SMTP setup tool.

Who It's For

This plugin suits developers or site owners who want a bare-bones SMTP configuration screen without the extras found in larger plugins like email logs, dashboards, or provider integrations. It works well for a single small WordPress site that just needs to fix unreliable mail delivery and nothing more. Agencies or non-technical users running multiple sites will likely find the feature set too thin.

Who Should Skip It

Anyone needing email logs, provider-specific integrations (SendGrid, Mailgun, SES), backup SMTP, or alerting should skip this and use a more capable alternative. If you want diagnostics, dashboards, or responsive support, this plugin does not provide them.

The Bottom Line

Simple SMTP does exactly what its name promises and nothing more, which is both its appeal and its weakness. The 66.38/100 quality score reflects strong ratings and recent maintenance dragged down by tiny install numbers and unresolved support threads. For most WordPress users, a more established SMTP plugin with logging and provider integrations will deliver better long-term value.
