I am trying to send a newsletter containing multiple links and anchors to navigate through the page. Usually this works fine but the links no longer work now and open a new page instead (my mailbox). I've noticed that the code of my links in the original page:
<a class="western" href="#Menu">Menu</a>
is automatically turned into the following in the email received :
<a class="western" target="_blank" rel="noreferrer noopener" href="#Menu">Menu</a>
Any idea what might be causing this and how to fix it?
Different e-mail clients support different HTML features.
Anchor links, for example, are not very well supported at all.
An e-mail client can display your HTML in any way it wants: filtered, modified or even not at all. It's out of your hands, in this case.
