About this plugin
OrangeSMTP replaces WordPress’s default mail function with a reliable SMTP connection, ensuring your emails actually reach the inbox — not the spam folder.
Whether you’re running a WooCommerce store, a membership site, or a business blog, OrangeSMTP gives you complete control over how your WordPress emails are sent, tracked, and monitored.
Why WordPress Emails Fail
By default, WordPress sends emails using the PHP mail() function, which has no authentication. Most email providers reject or silently drop these messages. OrangeSMTP routes your emails through a trusted SMTP provider with proper authentication, so your messages are delivered reliably every time.
12+ Email Providers Supported
Connect to the provider that works best for you:
- Gmail / Google Workspace — Send using your Google account with App Password or OAuth
- Mailgun — API + SMTP with open & click tracking
- Amazon SES — High-volume sending with AWS reliability
