WordPress Email-Related Plugins

WordPress hands outbound mail to whatever the host’s PHP-mail path allows, and most hosts have stopped letting that path work reliably. The reviews below cover the mailer plugins that fix this by routing through a real SMTP or API service, the logging utilities that make outbound mail auditable, and the form plugins whose own mail behaviour affects the rest. If a mailer isn’t already installed, start with the two below.

Start here

Two mailer plugins cover almost every WordPress email setup. WP Mail SMTP is the easiest to recommend when a working setup on day one matters more than budget or licensing preference — it’s the most-installed mailer in the category. FluentSMTP is the pick for sites that would rather run open-source and skip the Awesome Motive upselling pressure; the free version covers everything most sites need.

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).
FluentSMTP review

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

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.
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.
Disable Emails Review

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

Meow Mailer is a new free WordPress mailer plugin from Jordy Meow. Fourteen providers, OAuth for Gmail, Microsoft 365, and Zoho. No Pro tier, no tracking.
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.
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.
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.
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.
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 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.
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.
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.
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.
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.
