Can't send email through SendGrid

Question

I\'m following the example from SendGrid\'s site and as credentials I\'m pasting it what they gave me in the Azure portal. Still, I get this error message.

Answer 1

public static bool SendMailBySendGrid(string offMail, string mailFormatDetails,string subject,string ccMail=null,string bccMail=null)
{
  string mailFromId = System.Configuration.ConfigurationManager.AppSettings["Sender"];
  SendGridMessage sndmsg = new SendGridMessage();
  sndmsg.From = new MailAddress(mailFromId);
  sndmsg.To = new MailAddress[] { new MailAddress(offMail) };
  if (!string.IsNullOrEmpty(ccMail))
    sndmsg.Cc = new MailAddress[] { new MailAddress(ccMail) };
  if(!string.IsNullOrEmpty(bccMail))
    sndmsg.Bcc = new MailAddress[] { new MailAddress(bccMail) };
  sndmsg.Subject = subject;         
  sndmsg.Html = "
" + mailFormatDetails + "
";
  bool result= SendEmail(sndmsg);
  return result;
}

Include using SendGrid; in your project.
