Sendgrid API返回禁止的C＃

如何解决Sendgrid API返回禁止的C＃

我正在做sendgrid文档中显示的所有操作

    var client = new SendGridClient(apiKey);
    var from = new EmailAddress("test@example.com","Example User");
    var subject = "Sending with SendGrid is Fun";
    var to = new EmailAddress("whereiwanttosendemail@mail.com","Example User");
    var plainTextContent = "and easy to do anywhere,even with C#";
    var htmlContent = "<strong>and easy to do anywhere,even with C#</strong>";
    var msg = MailHelper.CreateSingleEmail(from,to,subject,plainTextContent,htmlContent);
    var response = await client.SendEmailAsync(msg);
    Console.WriteLine(response.StatusCode);

解决方法

“发件人”邮件应在SendGrid中注册为经过验证的发件人。设置->发件人身份验证。
