Simple, reliable SMTP and transactional email for WordPress
Royal SMTP is a lightweight email plugin that ensures your WordPress emails are delivered reliably. Connect to SendGrid, Brevo, Mailgun, Resend, SMTP.com, or any custom SMTP server — including Gmail and Google Workspace.
WordPress uses PHP mail() by default, which most hosts block or throttle. Royal SMTP routes your emails through a proper mail service so contact forms, password resets, and WooCommerce order notifications actually reach the inbox.
