Gmail SMTP

What It Does

Gmail SMTP replaces WordPress's default PHP mail function with authenticated SMTP sending through Google's Gmail servers. It uses OAuth 2.0 so you can grant sending permissions without storing a raw Gmail password in your wp-config file. In practice, this means contact form notifications, order confirmations, and other transactional emails from your site are delivered reliably instead of landing in spam.

Who It's For

This plugin is a reasonable fit for small site owners who already use a Google Workspace or personal Gmail account and want a no-frills way to send WordPress emails without paying for a third-party mailer. It works well for low-volume sites such as personal blogs, portfolios, or small business sites that send only a few hundred emails per day and do not need detailed logging or analytics.

Who Should Skip It

If you run a WooCommerce store, membership site, or any operation that sends more than a few hundred transactional emails per day, you should skip this plugin because Gmail's sending limits (500 recipients per day for Workspace, 500 per day for personal Gmail) will quickly become a bottleneck. Anyone who needs email logs, delivery tracking, or multi-mailer failover should look at a more full-featured SMTP plugin instead.

The Bottom Line

Gmail SMTP is a competent, well-maintained, narrowly focused plugin that does one thing, Gmail sending with OAuth, and does it cleanly with modern WordPress and PHP requirements. Its small install base, thin support history, and Gmail's tight sending limits make it a poor choice for high-volume or commercial sites. For a personal blog or small site already on Google Workspace, it is a sensible pick; everyone else will get more value from WP Mail SMTP or FluentSMTP.
