我正在尝试撰写时事通讯，但在GMail上进行测试时无法隐藏响应内容。在Outlook和Yahoo上一切正常，但如果我尝试转发电子邮件，隐藏的内容是可见的。
我测试使用：
putsmail > 我用它在Outlook、Yahoo和GMail
1上发送测试。Yahoo > 看起来不错，但是当我尝试转发电子邮件时，隐藏的内容是可见的；
2. Outlook > 看起来不错，但是当我尝试转发电子邮件时，隐藏的内容是可见的；
3. GMail > 可见的隐藏内容。mailchimp > 这适用于我只在Outlook上进行测试，它看起来不错（它隐藏了响应内容），但是当我尝试转发电子邮件时，隐藏的内容不再隐藏。
这是我的代码 () 的一部分：
