Description
Post SMTP Pro is a WordPress plugin that sends your site's email through an SMTP service such as Gmail, Outlook, Amazon SES, Mailgun, or SendGrid. It records each message in an email log and notifies you through channels like email, Slack, SMS, or its mobile app when a delivery fails. A backup mailer can take over if your main one stops working.
Key Features
- OAuth 2.0 Authentication – You connect supported mailers through API-based authentication instead of storing SMTP passwords on your site.
- Detailed Email Logs – Every WordPress email is recorded with its delivery status, subject, recipient, error message, and attachments.
- Backup SMTP Mailer – You can set a fallback mailer so transactional emails still go out if your primary SMTP service fails.
- Email Failure Alerts – When a message fails to send, the plugin notifies you through email, Slack, SMS, Microsoft Teams, or the mobile app.
- Auto-Retry Failed Emails – You set retry limits and the plugin automatically resends failed emails until they are delivered.
- Email Health Reports – Daily, weekly, or monthly reports show sent, delivered, failed, and opened emails along with performance charts.
- Resend From Log – Failed messages can be resent straight from the email log screen without leaving WordPress.
Who Is It For
This plugin is for WordPress site owners and administrators who need their site's email to arrive reliably, including those sending notifications, newsletters, or transactional messages. It suits people who want to connect a mailer such as Gmail, Outlook, or Amazon SES and keep a record of what was sent.
