Code Sample to Send Email

The provided code snippet demonstrates how to use the Mailgun API to send a message using the MailMessage class of the Aspose.Email for .NET.

1. Create a new instance of the MailMessage class.
2. Create the necessary options and initialize the client object.
3. Use the Send method of the client object (Mailgun client) to send the MailMessage (eml) created in the previous step.
4. Set up the monitoring of the sending process with the resp property and the display of each error message if any.

using Aspose.Email;
using Aspose.Email.Clients.DeliveryService;
using Aspose.Email.Clients.DeliveryService.Mailgun;
    
var domain = "YOUR_MAILGUN_DOMAIN";
var privApiKey = "YOUR_MAILGUN_PRIVATE_API_KEY";
var opt = new MailgunClientOptions { Domain = domain, ApiKey = privApiKey };
    
IDeliveryServiceClient client = DeliveryServiceClientFactory.Get(opt);

MailMessage eml = new MailMessage(fromAddress, toAddress, subject, body);

var resp = client.Send(eml);

if (!resp.Successful)
{
    foreach (var error in resp.ErrorMessages)
    {
        Console.WriteLine(error);
    }
}

With our advanced API, you can take advantage of the asynchronous method to send emails. The asynchronous method starts the email sending process in the background, making it possible to execute other tasks in the meantime. Launch the method with just a line of code:

await client.SendAsync(eml);
