未显示 Gmail 退订链接 [英] Gmail unsubscribe link does not appear

问题描述

在 Gmail 中，当您收到来自新闻列表的电子邮件时，您会在电子邮件地址旁边看到一个取消订阅"链接，如下所示:

In Gmail when you have an email from a newslist, you get a 'unsubscribe' link next to the email address, like this:

Google+ <[e-mail]> Unsubscribe

有一个名为 List-Unsubscribe: 的标头，用于标识 url 或电子邮件.

There is header named List-Unsubscribe: which identifies the url or email.

在 gmail 中，我可以看到电子邮件的原件以查看标题:

In gmail I can see original of email to see headers:

Received-SPF: pass (google.com: domain of [e-mail] designates 123.123.123.123 as permitted sender) client-ip=123.123.123.123;
Authentication-Results: mx.google.com;
   spf=pass (google.com: domain of [e-mail] designates 123.123.123.123 as permitted sender) smtp.mail=[e-mail];
   dkim=pass header.i=@domain.com
List-Unsubscribe: <http://domain.com/uns.html?test=wdqwqw>

我设置了 List-Unsubscribe 标头，spf 和 dkim 验证通过.

I have List-Unsubscribe header set, spf and dkim verification pass.

有什么问题吗?为什么gmail不显示退订链接?

What can be wrong? Why gmail does not show unsubscribe link?

推荐答案

退订选项是 只显示给信誉高的发件人:

这目前仅适用于某些发件人.我们积极鼓励发件人支持自动退订——我们认为 100% 应该.我们不会为垃圾邮件发送者的消息提供取消订阅选项:我们不能相信他们实际上会取消订阅您，他们甚至可能会发送你更多的垃圾邮件.因此，您只会看到发件人的取消订阅选项我们很确定不是垃圾邮件发送者，实际上会尊重您的取消订阅请求.我们对哪个非常保守一开始就信任发件人；随着时间的推移，我们希望提供能够取消订阅更多电子邮件.

This only works for some senders right now. We're actively encouraging senders to support auto-unsubscribe — we think 100% should. We won't provide the unsubscribe option on messages from spammers: we can't trust that they'll actually unsubscribe you, and they might even send you more spam. So you'll only see the unsubscribe option for senders that we're pretty sure are not spammers and will actually honor your unsubscribe request. We're being pretty conservative about which senders to trust in the beginning; over time, we hope to offer the ability to unsubscribe from more email.

还要注意，首选的列表取消订阅方法是 mailto，而不是 http.例如，Outlook.com 只支持 mailto.

Also note that the preferred list-unsubscribe method is mailto, not http. Outlook.com for example only honors mailto.
