SendGrid Benefits

It provides 24/7 customer support. It also has click tracking mechanism, Spam Reports, and if your mail gets bounced back, SenGrid tracks that as well. You can set daily/monthly mailing functionality over SendGrid API just to track how many emails went well or bounced back. If ever SendGrid API is down, it puts those emails in queues and sends it again once it is up.

So, it works on customer satisfaction with huge support.

  6.             Subject = "Subject line",  
  7.             TemplateId = "fb09a5fb-8bc3-4183-b648-dc6d48axxxxx",

  10.             //HtmlContent = "<strong>Hello, Email!</strong>",  
  11.     };  
  12.     //if you have multiple reciepents to send mail  
  13.     msgs.AddTo(new EmailAddress("""Pankaj Sapkal"));  
  14.     //If you have attachment  
  15.     var attach = new Attachment();  
  16.     //attach.Content = Convert.ToBase64String("rawValues");  
  17.     attach.Type = "image/png";  
  18.     attach.Filename = "hulk.png";  
  19.     attach.Disposition = "inline";  
  20.     attach.ContentId = "hulk2";  
  21.     //msgs.AddAttachment(attach.Filename, attach.Content, attach.Type, attach.Disposition, attach.ContentId);  
  22.     //Set footer as per your requirement  
  23.     msgs.SetFooterSetting(true"<strong>Regards,</strong><b> Pankaj Sapkal""Pankaj");  
  24.     //Tracking (Appends an invisible image to HTML emails to track emails that have been opened)  
  25.     //msgs.SetClickTracking(true, true);  
  26.     var responses = await client.SendEmailAsync(msgs);  
  27. }
