WordPress Email-Related Plugins

WordPress plugins that touch outbound email: SMTP mailers (WP Mail SMTP, FluentSMTP, Post SMTP), logging utilities, OAuth helpers, and the form plugins whose mail behaviour matters. Each review covers what the plugin does at the wp_mail layer, how the freemium tier compares to paid, and what breaks when it’s deactivated.

Gmail SMTP by naa986 Review

Free WordPress mailer for Gmail using XOAuth2 over SMTP. Works in 2026 — but requires a specific Cloud Console step to avoid the 7-day token expiry trap.

Zoho ZeptoMail plugin review

Zoho’s official WordPress plugin for Zeptomail (formerly TransMail). API-based, multi-agent routing, failed-email log, retry, test send. No Pro tier.
MailHawk plugin review

MailHawk is the WordPress plugin for the MailHawk sending service. Single-vendor by design, with in-admin DNS, logs, bounce handling, and account binding.
Send Emails with Mandrill: WordPress plugin review

Single-provider WordPress mailer for Mailchimp Transactional. Worth installing only when its three Mandrill-specific hooks earn the install over generic SMTP.
SMTP2GO plugin review

SMTP2GO’s official WordPress plugin routes wp_mail() through the SMTP2GO API. Single-provider, no logging, no fallback. The right pick when SMTP2GO is decided.
WP Test Email Review

Free WordPress test-send and 30-day email log utility. Smaller and simpler than Check & Log Email; the minimum-config alternative when richer logs are not needed.
Mailgun for WordPress Review

Mailgun’s official WordPress plugin routes wp_mail() through Mailgun’s API over HTTPS, bypassing host SMTP port blocks. Free plugin, no permanent free tier.
Mail Queue WordPress plugin review

Mail Queue by WDM queues WordPress email via the pre_wp_mail hook, leaving SMTP plugins untouched. Actively maintained: v1.5.1, tested up to WordPress 7.0.
GD Mail Queue Review

Queue-based wp_mail interceptor by Milan Petrovic. Capable architecture and the deepest logging panel in the category. Eighteen months without a release.
SMTP Mailing Queue WordPress plugin review

SMTP Mailing Queue replaced pluggable wp_mail and queued mail to JSON files on disk. Closed by author request on 2024-10-09; no longer on wp.org.
Log Emails Review

Free WordPress email logger that hooks phpmailer_init. The right pairing with Disable Emails on staging; second to Check & Log Email on production.
Disable Emails Review

Pluggable wp_mail() replacement that silences WordPress notifications on staging, dev, and freshly imported sites. Not a permanent outbound off-switch.
WP Offload SES review

WP Offload SES is the SES-only WordPress mailer. Domain verification, send-rate stats, and weekly health reports in the WordPress admin.
Check & Log Email Review

Free WordPress email logger that hooks wp_mail independently of the mailer. The standalone choice when the sending plugin works and logging is missing.
YaySMTP (by Yay Commerce) review

YaySMTP review — mailer plugin by Yay Commerce; free version includes Amazon SES, Outlook OAuth, and email tracking; Pro tier adds priority support only.
Contact Form 7 review

Contact Form 7 uses wp_mail(), so any mailer plugin routes its submissions automatically. Free, no Pro tier, add-ons fill the rest.
Post SMTP review

Post SMTP is the WordPress mailer plugin that pushes failed-send alerts to a mobile app. Logging, OAuth, and a fallback SMTP connection ship in the free version.
Easy WP SMTP (by SendLayer) review

Easy WP SMTP is the smaller of Awesome Motive’s two mailer plugins (500K+ installs). Free version covers most setups; full email logging is Pro.
SMTP Mailer review

SMTP Mailer connects WordPress to any SMTP server using credentials you supply. 70,000+ active installs, free core, SMTP session log on test sends.
WPForms Lite review

WPForms Lite is a free drag-and-drop form builder for WordPress. No local entry storage, no conditional logic, and most integrations require a paid plan from $49.50/year.
FluentSMTP review

FluentSMTP is the open-source WordPress mailer plugin from WPManageNinja. Logging, multiple connections, fallback, and OAuth, all in the free version.
WP Mail SMTP Review

The most-installed WordPress mailer plugin (4M+ sites). Broad mailer support and a setup wizard that works. Email logging requires the Pro plan ($99/year on renewal).
