GoSMTP Pro

GoSMTP Pro sends WordPress email through an SMTP connection or supported email service instead of the hosting provider’s PHP mail function. Hosting mail limits and sending server IP reputation can affect delivery. GoSMTP lets you connect site messages to the mail infrastructure you use.

Connect and test a mailer

Connections include custom SMTP, SMTP.com, Brevo (formerly Sendinblue), Mailgun, SendGrid, SparkPost, SendLayer, Postmark, and Maileroo. Pro connections include Elastic Email, SMTP2Go, Gmail, G Suite, Google Workspace, Outlook, Office 365, AWS, Zoho, Resend, and MailerSend.

Mailer setup can include a nickname, mailer type, and backup connection. Send a test email through the configured mailer to check its options and view the execution result.

Review and resend email

Email logging records messages sent from your website for record keeping, auditing, and troubleshooting. Logs include status, mailer provider, timestamp, and recipient details. Open an entry to review its body, headers, and delivery response, or export filtered logs as CSV.

• Resend a logged message, with the option to select a new recipient.
• Resend multiple messages from the email log wizard.
• Receive failed-delivery notifications through available channels such as Mail, Slack, and Discord.

Track sending and route messages

The Pro email report summarizes sent and failed counts, overall success rate, and daily performance. Smart Routing selects an SMTP provider based on message content, allowing transactional alerts and marketing messages to use various routes.

Use email abilities with AI clients

GoSMTP exposes abilities through the WordPress Abilities API for AI clients, assistants, and MCP adapters. Free abilities return settings, list configured mailers, and send a test email. Pro abilities can list email logs, display an individual log’s details, export logs as CSV, resend a logged message, and retrieve the sending report. The settings ability does not expose sensitive credentials.

Install and configure

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