Description:

Post SMTP Pro is a WordPress plugin that handles email delivery by connecting your site to an SMTP or API based mailer. It supports many services including Gmail and Google Workspace, Microsoft Office 365, Amazon SES, Brevo, SendGrid, Mailgun, Zoho Mail, Postmark, Elastic Email, Sparkpost, Mandrill, MailerSend, SendPulse, Mailjet, Resend, Emailit, Maileroo, SMTP2Go, SMTP.com, Mailtrap, Sweego and Cloudflare. Gmail and Microsoft accounts can be connected with a one click setup that avoids manual SMTP configuration.

The plugin keeps email logs where you can view error details, read full transcripts of sent emails, resend messages in bulk, and view or resend attachments. You can set a retention period for the logs. Failed emails can be resent automatically, with the number of attempts set after the first failure, and email quota scheduling lets you send messages in batches hourly, daily, weekly or monthly. Open email tracking shows how WordPress email performs, and a weekly email health report gathers deliverability statistics.

When an email fails, the plugin sends alerts through MS Teams, Slack, webhooks, a Chrome extension or Twilio SMS. The Post SMTP mobile app shows failure notifications and email logs, resends failed emails, and connects multiple WordPress sites, with MainWP support for managing SMTP configurations across sites. It suits WordPress site owners who need reliable email delivery and monitoring.

The vendor’s own page for Post SMTP Pro has the full details.

  • Email logging with error details, full transcripts, attachments, and a configurable retention period
