如何使用mailjet的[[PERMALINK]]发送电子邮件

I've been bugging on a problem involving mailjet's macro [[PERMALINK]].

I'm using package github.com/mailjet/mailjet-apiv3-go, with method SendMail(*mailjet.InfoSendMail).

The HTML code before send :

<span class="f11">
    Si ce message ne s'affiche pas correctement, <a style="color: #999999;" href="[[PERMALINK]]">consultez-le en ligne</a><br/>
</span>

The HTML code inbox (Gmail) :

<span class="f11">
    Si ce message ne s'affiche pas correctement, <a style="color: #999999;">consultez-le en ligne</a><br/>
</span>

This link becomes a text and the href attribute is removed. Why is that and how can I make it work?
