Gravity SMTP

Gravity SMTP is a WordPress SMTP plugin designed to help you send emails more reliably from your site and improve delivery rates. It replaces the default PHP mail sending approach with routing through secure SMTP providers and API-based email services, which is especially important for transactional and critical communications like notifications and user-related emails. It’s for site owners, marketers, agencies, and developers who want dependable delivery and visibility for emails triggered by WordPress Key features include built-in support for trusted SMTP and API-based providers such as SendGrid, Postmark, Mailgun, Brevo, Google, and Microsoft, plus a Custom SMTP option to connect to the SMTP-enabled servers you prefer. Gravity SMTP also includes email logging and reporting so you can track delivery and open status from inside your WordPress dashboard without leaving your admin workflow. For resilience, it supports alerts and backups by letting you choose a second email service and receive real-time notifications when emails fail to send. It further offers Gravity Forms integration for reliable sending of form notifications, alongside email management controls that let you turn off certain default WordPress email notifications and create suppression lists. Gravity SMTP is a strong fit for teams running marketing and lead-gen websites that depend on form notifications to reach sales and support quickly, as well as for sites that handle user registration, password resets, and other account-critical messaging. Agencies managing multiple client sites benefit from the centralized “send and track emails” workflow inside WordPress, especially when debugging deliverability issues or providing consistent reporting to clients. If you’re running a nonprofit or any organization with time-sensitive email communications, the backup-and-alert capability helps prevent silent failures by surfacing send issues early. On licensing, Gravity SMTP is not sold as a standalone product; it’s available with an active Gravity Forms Elite license or a Nonprofit license
