The Gravity Forms Mailgun Add-On is the official Gravity Forms extension that connects your WordPress forms with Mailgun's transactional email service, ensuring that your form notifications reliably reach your recipients' inboxes.
The problem is well known: by default, WordPress sends emails using PHP's native mail function, which lacks proper authentication and often ends up in the spam folder or simply doesn't get delivered. Some hosting providers even block this function entirely. If you've ever had a client claim they submitted a form and you received nothing, this add-on directly addresses that issue.
With this add-on, all your form notifications are sent through the Mailgun API, a service specialized in transactional email that offers a much higher delivery rate and better sender reputation. Setup is simple: install the add-on, create a free Mailgun account, authenticate your domain by adding the corresponding DNS records, and paste your private API key into the Gravity Forms settings.
The add-on is available on all Gravity Forms license plans and installs directly from the WordPress admin panel, in the Gravity Forms add-ons section. If your site relies on forms to generate business or serve your customers, this add-on is a minimal investment that will save you from lost emails and frustrated clients.
