在 Google Apps 脚本中访问已发送的电子邮件

我正在使用 Google 脚本发送一封电子邮件并查找对此的任何回复（应该只有一个回复，但这与这里并不真正相关）。理论上，我可以使用搜索、标签和ReplyTo:选项中GmailApp.sendEmail跟踪事情。然而，我遇到了一些重叠的问题/担忧，因为：

• 我每周都会发送相同的电子邮件，因此搜索很挑剔
• Scripts/Gmail 似乎更新得不够快，无法找到刚刚发送的电子邮件

我想使用 Gmail 为每封电子邮件提供的唯一 ID，但由于GmailApp.sendEmail方法返回一个GmailApp对象而不是GmailMessage反对这似乎不可能。

那么，如何以编程方式跟踪我以编程方式发送的电子邮件？

下面是我正在使用的代码。愿意接受工作流程和方法的变化，但更愿意将其保留在 Google Apps 脚本中。

function trigger(minutes){
ScriptApp.newTrigger("checkForEmail")
.timeBased()
.after(100*60*minutes)
.create()
};

function sendEmail(){
//send the email
    GmailApp.sendEmail("[email protected] /cdn-cgi/l/email-protection","Subject","Body",{replyTo: "[email protected] /cdn-cgi/l/email-protection"});
    //get the Id of the email that was just sent
    var emailId GmailApp.search("replyTo:[email protected] /cdn-cgi/l/email-protection",0,1)[0].getMessages()[0];
    ScriptProperties.setProperty("emailId", emailId);
    //set a trigger to check later
    trigger(45)
    };

function checkForEmail(){
var emailId = ScriptProperties.getProperty("emailId");
var email = GmailApp.getMessageById(emailId);
var count = email.getThread().getMessageCount();
var command = "checkForEmail"
if (count == 1){
//set trigger to check again
ScriptApp.deleteTrigger(command)
trigger(5)
}
if (count == 2){
//do stuff with the new email: alert me, download attachments, etc.
var attachments = email.getThread().getAttachments()
ScriptApp.deleteTrigger(command);
}
else {
//something is weird, let me know
var body = "there was an error with checking an email ("+emailId+")."
GmailApp.sendEmail("[email protected] /cdn-cgi/l/email-protection","Error",body);
ScriptApp.deleteTrigger(command);
};
};

尝试制作草稿，然后发送。

var message = GmailApp.createDraft("[email protected] /cdn-cgi/l/email-protection","Subject","Body",{replyTo: "[email protected] /cdn-cgi/l/email-protection"}).send();
