Add it to your android project

• In android/setting.gradle

...
include ':RNMail', ':app'
project(':RNMail').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-mail/android')

• In android/app/build.gradle

...
dependencies {
    ...
    compile project(':RNMail')
}

• register module (in MainActivity.java) if MainActivity extends Activity

import com.chirag.RNMail.*;  // <--- import

public class MainActivity extends Activity implements DefaultHardwareBackBtnHandler {
  ......

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mReactRootView = new ReactRootView(this);

    mReactInstanceManager = ReactInstanceManager.builder()
      .setApplication(getApplication())
      .setBundleAssetName("index.android.bundle")
      .setJSMainModuleName("index.android")
      .addPackage(new MainReactPackage())
      .addPackage(new RNMail())              // <------ add here
      .setUseDeveloperSupport(BuildConfig.DEBUG)
      .setInitialLifecycleState(LifecycleState.RESUMED)
      .build();

    mReactRootView.startReactApplication(mReactInstanceManager, "ExampleRN", null);

    setContentView(mReactRootView);
  }

  ......

}

• register module if MainActivity extends ReactActivity

• In MainApplication.java

import com.chirag.RNMail.*; // <--- import

public class MainApplication extends Application implements ReactApplication {
    ....
  
    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
          new RNMail()      // <------ add here
      );
    }
  };

Add it to your iOS project

1. Run npm install react-native-mail --save
2. Open your project in XCode, right click on Libraries and click Add Files to "Your Project Name" (Screenshot) then navigate to node_modules/react-native-mail and select RNMail.xcodeproj (Screenshot).
3. Add libRNMail.a to Build Phases -> Link Binary With Libraries (Screenshot).
4. Whenever you want to use it within React code now you can: var Mailer = require('NativeModules').RNMail;

Example

var Mailer = require('NativeModules').RNMail;

var MailExampleApp = React.createClass({
  handleHelp: function() {
    Mailer.mail({
      subject: 'need help',
      recipients: ['[email protected]'],
      ccRecipients: ['[email protected]'],
      bccRecipients: ['[email protected]'],
      body: '',
      isHTML: true, // iOS only, exclude if false
      attachment: {
        path: '',  // Absolute path or URI of the file from which to read data
        type: '',   // Mime Type: jpg, png, doc, ppt, html, pdf
        name: '',   // Optional: Custom filename for attachment
      },
      chooserLabel: '' // Android only, the label displayed on chooser
    }, (error, event) => {
        if(error) {
          AlertIOS.alert('Error', 'Could not send mail. Please send a mail to [email protected]');
        }
    });
  },  
  render: function() {
    return (
      <TouchableHighlight
            onPress={row.handleHelp}
            underlayColor="#f7f7f7">
	      <View style={styles.container}>
	        <Image source={require('image!announcement')} style={styles.image} />
	      </View>
	   </TouchableHighlight>
    );
  }
});

Note

On Android, the callback will only be called if an error occurs. The event argument is unused!

Here is how it looks:
