How can I set up anchors in Mosaico mailing?
looks like there is no way to do this via the limited 'what you see is what you get' (WYSIWYG) editor, so this would have to be done in the code of the block you are working in, by clicking onto the source button &lt; > And then using the html for an anchor link. 

For example your first anchor link can be called 'one'

You would use it as follows. If you had a list of heading points at the top of the email as such.

1) My heading one

2) My heading two

3) My heading three

Then you would put the anchor in like this:

&lt;ol&gt;
    &lt;li&gt;
        &lt;a href="#one"&gt;My first heading&lt;/a&gt;&lt;/li&gt;
    &lt;li&gt;
        &lt;a href="#two"&gt;My second heading&lt;/a&gt;&lt;/li&gt;
    &lt;li&gt;
        &lt;a href="#three"&gt;my third heading&lt;/a&gt;&lt;/li&gt;
&lt;/ol&gt;

&lt;a name="one"&gt;1) &lt;/a&gt;&lt;p&gt;My section one here&lt;/p&gt;
&lt;a name="two"&gt;2) &lt;/a&gt;&lt;p&gt;My section two here&lt;/p&gt;
&lt;a name="three"&gt;1) &lt;/a&gt;&lt;p&gt;My section three here&lt;/p&gt;
