Mailgun

Transactional email delivery via API for developers

What Mailgun does

Mailgun provides an email delivery API aimed at technical users and development teams handling transactional or marketing email at scale. The service handles infrastructure for sending, receiving, and tracking email, allowing teams to integrate email functionality into their applications without managing mail servers or protocols directly. Mailgun is operated by a company with experience in cloud-based email services and is generally positioned for backend integration rather than drag-and-drop marketing campaigns. Its focus is on reliable delivery, tracking, and programmatic control, fitting best within web applications, SaaS platforms, or services needing automated email workflows.
