Sending a Simple Email with Mailgun Java SDK

Once you have your project set up and the Mailgun Java SDK added, you can start sending emails. Here's a simple example of sending a basic email using the SDK:

import com.mailgun.api.MailgunClient;
import com.mailgun.api.MailgunMessages;
import com.mailgun.api.exceptions.MailgunException;

public class SendEmail {
    public static void main(String[] args) throws MailgunException {
        // Your Mailgun API key
        String apiKey = "your_api_key";
        // Your Mailgun domain name
        String domain = "your_domain.mailgun.org";

        // Create a Mailgun client
        MailgunClient client = new MailgunClient(apiKey, domain);

        // Create a Mailgun message builder
        MailgunMessages.MessageBuilder messageBuilder = client.message()
                .setFrom("Excited User ")
                .addTo("[email protected]")
                .setSubject("Welcome to our app!")
                .setText("This is a simple email sent with Mailgun and Java");

        // Send the email
        client.sendMessage(messageBuilder);
    }
}
