我使用SendGrid提供的Senddrid C#库来发送消息。我有动态模板。用户点击后，它会发送带有动态字段的电子邮件。
所以问题是，通过某种方式，我不能使用虚构的电子邮件，因为我必须使用真实的/激活的电子邮件。以防万一，输入是有效的，或者从appseting.js获得，并且也是有效的。它的问题是"；SetFrom"；方法模板id或app_key 没有问题
真正的电子邮件-例如，我指的是我可以登录并发送消息的电子邮件！假电子邮件-用作存根。例如no-reply@gmail.com
private async Task mySendEmail(string toAddress, string templateId, JObject dynamicTemplateData, string? toWhome = null, string? setFromEmail = null, string? setFromName = null)
{
if (setFromEmail is null)
setFromEmail = sendGridConfig.SendGridApiFrom;
if (setFromName is null)
setFromName = sendGridConfig.SendGridApiFromDisplayName;
// var foo = sendGridConfig.SendGridApiKey;
var client = new SendGridClient(sendGridConfig.SendGridApiKey);
var msg = new SendGridMessage();
msg.AddTo(new EmailAddress(toAddress, toWhome));
//msg.SetFrom("my-real-email@gmail.com", setFromName); // if using real email it works
msg.SetFrom(new EmailAddress("test@example.com", "Example User 0")); // fictional email have bad requests
msg.SetTemplateData(dynamicTemplateData);
msg.SetTemplateId(templateId);
var response = await client.SendEmailAsync(msg); // Bad request
}
结果的输出
{"from":{"name":"Example User 0","email":"test@example.com"},"personalizations":[{"to":[{"name":"Stone Ocean","email":"count_zero@inbox.lv"}],"dynamic_template_data":{"url":"CUCUMBER@INBOX.LV","password":"TEREMOK"}}],"template_id":"d-2f393a3c5ca7451ea856fc1acadf0bd7"}
Forbidden
{"errors":[{"message":"The from address does not match a verified Sender Identity. Mail cannot be sent until this error is resolved. Visit https://sendgrid.com/docs/for-developers/sending-email/sender-identity/ to see the Sender Identity requirements","field":"from","help":null}]}

有什么想法吗？为什么SetFrom需要真实的电子邮件而不是虚构的，以及如何避免它？
根据SendGrid，发件人的电子邮件(从发件人发送的电子邮件)必须经过SendGrid的验证才能从中发送电子邮件。否则，请求会引发错误。为什么点击
