Gravity SMTP

Gravity SMTP is a WordPress plugin developed by the Gravity Forms team that solves one of the most common problems on websites with forms: reliable email delivery. Instead of relying on WordPress's default PHP Mail function, which is often unreliable and causes emails to end up in spam or get lost, Gravity SMTP connects your site with trusted email sending services to ensure that every notification actually reaches its destination.

This plugin is designed for those who rely on advanced forms in WordPress and need every generated email to arrive: lead capture, internal requests, bookings, or automated email-based processes. Its setup wizard allows you to integrate your site with recognized providers such as SendGrid, Mailgun, Postmark, and Brevo quickly and easily, without the need for advanced technical knowledge. It also offers support for custom SMTP, allowing you to connect any other email service provider through an intuitive control panel.

Its standout features include email logging, which lets you see which messages have been sent from your site, with details such as the date, the plugin that generated the email, and its status. It also includes a tool to send test emails directly from the WordPress dashboard, making it easy to verify that the integration works correctly before relying on it. Open tracking allows you to view email open analytics within your WordPress dashboard, and the sending fallback system ensures that if an email fails with the primary service, it is automatically resent via a secondary service.

Gravity SMTP also offers real-time alerts for failed emails, with support for SMS via Twilio and webhooks, as well as email suppression features to manage exclusion lists directly from the dashboard. Although it integrates perfectly with Gravity Forms, it is a standalone plugin that works with any WordPress site, improving the delivery of all transactional emails on the site, including those generated by other plugins.

If your business depends on your website's forms generating leads and inquiries that actually reach your inbox, Gravity SMTP is the solution you need to send emails with confidence and significantly improve delivery rates.
