email - AppleScript 和 Mail.app : checking if new messages contain a string

Question

我正在编写一个脚本来检查是否已提交特定的 Web 表单。

到目前为止的脚本是这样写的:

tell application "Mail"
check for new mail
set newmail to get the unread count of inbox
repeat with msg in newmail
    if msg's subject contains "New newsletter built by" then
        return msg's subject
    end if
end repeat
end tell

我的收件箱中有一封未读电子邮件供脚本使用，但我仍然收到错误消息:

error "Mail got an error: Can’t make 1 into type specifier." number -1700 from 1 to specifier

任何帮助都将不胜感激。

干杯!

Answer 1

tell application "Mail"
    check for new mail
    repeat until (background activity count) = 0
        delay 0.5 --wait until all new messages are in the box
    end repeat
    try
        return subject of (first message of inbox whose read status is false and subject contains "New newsletter built by ")
    end try
end tell
