Key Features of Mailgun

1. Email Sending via API and SMTP

With inbound routing and parsing capabilities, Mailgun extracts message content and metadata, allowing developers to trigger events or workflows based on email replies or custom headers. This is especially useful for applications that need to manage support tickets, surveys, or user-generated content.

3. Email Validation Services

Mailgun includes powerful email validation tools that help ensure messages are sent only to verified and deliverable addresses. This service reduces bounce rates, protects sender reputation, and increases campaign effectiveness by filtering out invalid, disposable, or mistyped email addresses before sending.
