Are you dealing with the **WordPress not sending emails** problem? Post SMTP helps you fix WordPress email delivery by connecting your site to a reliable **SMTP or API mailer.**

**Post SMTP is a free WordPress SMTP plugin** that helps you send WordPress emails securely and reliably through Gmail, Microsoft 365, Outlook, Amazon SES, Brevo, Mailgun, SendGrid, Postmark, Zoho Mail, and other supported email service providers.

Beyond SMTP, Post SMTP gives you the tools to **monitor WordPress email delivery.** Track sent and failed emails with **email logs**, inspect delivery errors, and get failure alerts when something goes wrong. You can also configure **backup SMTP connections** to keep your site’s emails moving if your primary mailer becomes unavailable.

With **[20+ SMTP and API mailer options,](https://postmansmtp.com/smtp-integrations/)** Post SMTP works with the email service you already use. Its monitoring and notification tools help you troubleshoot delivery problems faster and keep important WordPress emails on track.
