WordPress normally sends generated email through the PHP mail function. Configure GoSMTP Pro to route messages through an SMTP connection or a supported email provider API instead. Hosting mail limits and sending server IP reputation can affect delivery; the configured mailer determines which mail infrastructure sends your site’s messages.

Configure and test a mailer

Connect a custom SMTP provider or use SMTP.com, Sendinblue (shown as Brevo), Mailgun, SendGrid, SparkPost, SendLayer, Postmark, or Maileroo. Provider connections listed as Pro options include Elastic Email, SMTP2Go, Gmail, G Suite, Google Workspace, Outlook, Office 365, AWS, Zoho, Resend, and MailerSend.

Mailer setup supports nicknames, mailer types, and backup connections. Once configured, send a test email through the selected mailer to check its options and view the execution result.

Review and manage sent email

Email logging records messages sent from your site for reference, auditing, and troubleshooting. Each log entry shows its status, mailer provider, timestamp, and recipient details. Open an entry to review the message body, headers, and delivery response.

• Filter email logs and export matching entries as CSV.
• Resend a logged message, optionally to a new recipient, or resend multiple messages from the email log wizard.
• Receive failed-delivery notifications through Mail, Slack, or Discord.
• View sending reports with sent and failed totals, overall success rate, and a daily performance breakdown.

Route messages and use WordPress AI abilities

Smart Routing assigns SMTP providers based on message content, separating transactional alerts from marketing email so critical messages can use an appropriate route.

GoSMTP exposes abilities through the WordPress Abilities API for AI clients, assistants, and MCP adapters. Free abilities return global settings without exposing sensitive credentials, list configured mailers, and send a test email. Pro abilities can list email logs, display individual log details, export filtered logs as CSV, resend a logged message, and retrieve an aggregated sending report.

Install GoSMTP

In WordPress, open Plugins, pick Add New, search for GoSMTP, and install it. Configure a supported provider or custom SMTP connection, then send a test email to check the mailer settings before routing site messages through it.
