email - Sendgrid 发送电子邮件，但许多被推迟：状态代码 202

Question

我们正在使用 sendgrid 向大约 50k 封电子邮件发送每周时事通讯。我们有一个经过身份验证的域以及两个我们自己的 IP 地址。我们的脚本批处理一次向所有具有个性化的地址发送 500 封电子邮件。但是，当我们运行脚本时，许多电子邮件正在被处理，然后根据 sendgrid 日志被延迟。响应为 202。一些电子邮件会收到时事通讯，但其他电子邮件不会。有关如何解决此问题的任何建议？

Answer 1

Twilio SendGrid developer evangelist here. I would certainly follow flaxon's advice, check the dashboard and see what it says about your delivery as well as bounces or spam reports. There is a good article here on what being "deferred" means too.

I would also look into SendGrid's Marketing Campaigns. It is a better way to send bulk email, like to your 50k email list, than making several requests as you describe.
