Mailgun Technologies


Mailgun is the all-in-one, intelligent email delivery platform trusted by businesses, loved by developers.

Mailgun is how modern companies work with email. The platform’s ease of use, world-class support, and powerful APIs empower smart development teams to reach real customers at scale with a data-driven approach so their organization can grow faster.

Send and track your transactional and marketing messages effortlessly. Prevent fake signups and remove invalid email addresses from your list quickly. Partner with email experts to improve your deliverability and drive higher conversion rates.

Mailgun was founded in 2010 as a response to the lack of developer-friendly, API-based email services. The idea was to make it dead simple for developers to integrate email capabilities into your app. Since then, we’ve stayed laser-focused on deliverability and steered clear of shiny objects that won’t impact your success.

Today, Mailgun helps hundreds of thousands of companies and leading brands around the world send hundreds of billions of emails every year. We’re proud of what we’ve built, and this is only the beginning.
