Note: Requires the <a href="https://wordpress.org/plugins/post-by-email/" rel="ugc">Post By Email</a> plugin.
The plugin filters the post content after a post has been created via the <a href="https://wordpress.org/plugins/post-by-email/" rel="ugc">Post By Email</a> plugin. 
If the post content contains only a URL it automatically assigns the ‘link’ <a href="https://codex.wordpress.org/Post_Formats" rel="nofollow ugc">post format</a> to the post and wraps the URL in a link tag.

<li>The category to which Linkmarklet posts will be added</li>
<li>The Custom Field name you’re using to store the submitted link</li>
<li>The Post Format you would like to use for each post</li>

</ol>
That’s about it. Clicking Publish pushes the entry live instantly (or schedules it). Clicking Save will store the post as a Draft.
