SMTP2GO’s WordPress plugin replaces the default built in wp_mail() functionality (phpmailer) and sends your email via SMTP2GO’s API and industry leading email delivery platform.

SMTP2GO provides valuable insights into every aspect of your email’s life cycle, enabling you to track delivery rates, opens, clicks, and bounce rates. Whether your email is transactional, marketing, newsletter, contact form, or notification – we have got you covered.

The main benefits of using the official SMTP2GO plugin:

  • We have made our plugin as easy and low maintenance as possible – you can set it up in under ten minutes.
  • Take over from the default WordPress email system for more reliable delivery – you can be confident your emails have arrived at their destination inbox successfully.
  • Get access to our intuitive real-time reporting tools. You can uncover what is going on behind the scenes with delivery, open rates, click rates, bounce, and unsubscription reports.
  • We offer secure worldwide servers with intelligent routing for network redundancy and speedy delivery.
  • We handle SPF and DKIM on your behalf. SMTP2GO can even turn your “http” links into “https”.
  • Diagnose and resolve delivery issues with our insightful reporting page, or reach out to our award-winning support team who are available almost 24/7 to help address problems in a timely, friendly fashion.
  • We have a dedicated Review team who constantly monitor the reputations of our IP’s and we proactively alert members to any suspicious changes in their email regimen.
  • Avoid poor reputation and throttling or limitations from over-used shared web hosts and other providers.
