What It Does

YaySMTP replaces WordPress's default wp_mail() function with a properly configured SMTP connection so transactional emails actually reach inboxes. It also logs every outgoing email, tracks opens and clicks, generates visual reports, and exports the log as CSV. WooCommerce users get a built-in preview tool for order and customer emails before they go out.

Who It's For

Small to mid-sized WooCommerce stores and WordPress sites that need reliable email delivery plus visible proof that messages were opened or clicked. It's a strong fit for site owners who want email logging and basic deliverability in one free plugin without configuring a full SaaS platform.

Who Should Skip It

Sites already running WP Mail SMTP by WPForms or FluentSMTP, since both have larger install bases and richer ecosystems. Anyone sending high-volume marketing email through a dedicated ESP like Mailchimp or Sendinblue also does not need this, since that traffic bypasses wp_mail() entirely.

The Bottom Line

YaySMTP delivers a genuinely useful feature set for the price of zero, and the coding signals (recent updates, WordPress 7.0.1 compatibility, perfect rating) are all positive. The honest concern is its 10,000-install footprint relative to category leaders 400x its size, which means fewer third-party reviews, smaller community knowledge, and an unproven track record at scale. Worth trying on a low-stakes site first; for a high-traffic store, the alternatives carry less risk.
