Google+ related page appearing in Gmail

Question

Gmail have been displaying related Google+ pages on the right of the page when I open certain emails. It looks like this:

I can't find any documentation on it though and trying to figure out how to associate a particular email address with a Google+ page. For example, say we have a Google+ page http://plus.google.com/example and we have linked it to its official domain http://example.com - it does not automatically display the Google+ page in Gmail next to all emails that come from the example.com domain.

I am trying to specifically have the related page display from all emails that come from [email protected] - but I can't seem to find work out what I need to do to link that email to the Google+ page.

Does anyone know how to do it?

Thanks in advance.
