About Mailgun

Mailgun is a developer-focused email API service for sending, receiving, and tracking transactional and marketing emails at scale. It provides RESTful APIs and SMTP relay for easy integration.

Key features include email validation (real-time address verification), inbound routing (receiving and parsing emails), deliverability tools (IP reputation monitoring, feedback loops), and detailed analytics.
