Perhaps it is just basic HTML, but I’m positive that this will benefit someone while formatting for example a workflow email.

Instead of having that ugly long URL inside the body of the email, we would like to have some text that says “Click here” to link to the appropriate document / list item etc.

A hyperlink is simply created by typing the following code in  the body of your email:
<a href=”http://MyServerName/”>Click here</a>

Replace the http://MyServerName for some item you would like to link to.

Pretty much all email clients will read the html code and convert it into a nice looking link.
