Easily send email from your WordPress site through Mailgun using the HTTP API or SMTP.
Security History
What It Does
Mailgun for WordPress routes outgoing email from your site through Mailgun's transactional email service, supporting both the Mailgun HTTP API and standard SMTP. It replaces the default PHP mail function with a more reliable delivery path, helping reduce emails landing in spam. Configuration is straightforward through the WordPress admin and requires a Mailgun account and API key.
Who It's For
This plugin is best for developers and site owners who already use, or are committed to using, Mailgun as their transactional email provider and want a lightweight, single-purpose integration. It suits small to medium WordPress sites that send transactional email like contact form submissions, order notifications, or password resets and need better deliverability than PHP mail.
Who Should Skip It
If you are not already on Mailgun, or you send high volumes of marketing email alongside transactional email, skip this and choose a multi-provider SMTP plugin like FluentSMTP or WP Mail SMTP. Users who need built-in email logging, open and click tracking, or a managed dashboard for multiple mail providers will also find this plugin too narrow.
The Bottom Line
Mailgun for WordPress is a focused, well-maintained plugin that does one thing, Mailgun delivery, and does it cleanly with current WordPress and PHP support. The catch is its tiny community footprint: only 49 ratings and zero support threads in the repo, so troubleshooting is largely on you or Mailgun's docs. If you are a Mailgun customer who values a lightweight plugin over feature breadth, it is a solid pick; otherwise a multi-provider SMTP plugin is the safer default.
Related Plugins
Pick this instead if you want a battle-tested plugin with 4 million installs, built-in email logging, and support for many providers beyond Mailgun.
Choose FluentSMTP if you want Mailgun support along with Amazon SES, SendGrid, Postmark, and Google in one interface, plus email logging.
Go with Post SMTP if deliverability tooling like email logs, failure alerts, and a backup SMTP fallback matter more than a minimal Mailgun-only setup.
Select Easy WP SMTP if you prefer a simpler UI, broad provider support including Gmail and Office 365, and basic email logging out of the box.
Flamingo is not a direct competitor since it captures form submissions rather than routing mail, but pair it with any SMTP plugin if you also need to store inbound contact form messages.
