有办法使用 API like(sendgrid, mailgun) 通过 Firebase 云函数发送电子邮件
或者它被视为出站连接？

幸运的是，有一个 Google 拥有的服务可以发送邮件；邮箱！有一个quick-start sample available or a related Whosebug answer，但该方法有以下限制：
You may see this message if you send an email to a total of more than 500 recipients in a single email and or more than 500 emails in a day sent.
没有 Google 拥有的邮件 API 允许无限制的电子邮件。正如上面链接的快速入门示例所述：
If you are planning on sending a large number of emails you should use a professional email sending platform such as Sendgrid, Mailjet or Mailgun.
