Java language

Java is a widely used, object-oriented programming language often used to build large-scale web applications, backend services, and Android apps.  

In the context of email, Java can be used to: 

  • Send email via SMTP using libraries like javax.mail 
  • Make API calls to Email Service Providers (ESPs) like Mailgun to send or track messages 
  • Process webhook events (e.g., parsing inbound mail or tracking clicks/opens) 
  • Integrate email functionality into enterprise systems 

Mailgun supports sending via both SMTP and RESTful API endpoints and can be integrated with Java applications using standard HTTP client libraries.  

Note: Java is not to be confused with JavaScript, which is primarily used in web development and should not be used inside HTML emails due to lack of support and security concerns.
