aws_secret_access_key = your_secret_key

Create Amazon SES Client

var sesClient = asEmailSender.createSesClient();

Create Mailgun Client

var asEmailSender = require('as-email-sender');
var mailgunCredential = {
    "apiKey": "xxxxxxxxx",
    "domain": "yyyyyyyy.mailgun.org"
}
asEmailSender.createMailgunClient(mailgunCredentials);

Example code

var asEmailSender = require('as-email-sender');

// create two clients (providers) for auto failover
var clients = [
    asEmailSender.createMailgunClient(mailgunCredentials),
    asEmailSender.createSesClient()        
]

var sender = new asEmailSender.Sender(clients, '[e-mail]');

var params = sender.createBaseParams();
params.toAddresses = ['[e-mail]'];
params.body = 'test';
params.subject = 'foo subject';

sender.sendEmail(params)
.then(function(result) {
    console.log(result);
})
.catch(function(e) {
    console.log(e);
});

Auto failover

The clients will be used in the order you have defined in the clients array.

When one client failed to send, the sending request will be retried by the subsequent client.

If all clients failed, a rejected promise will be returned.
