     using Mailjet.Client;
     using Mailjet.Client.Resources;
     using Newtonsoft.Json.Linq;
     using System;
     using System.Threading.Tasks;

         static async Task Main(string[] args)
         {
             MailjetClient client = new MailjetClient("your-api-key", "your-secret-key");

             });
             
             MailjetResponse response = await client.PostAsync(request);
