Advanaced Threat Protection Safe Links user communicaiton

Hi guys we are about to enable the EMS ATP Safe link and Safe attachemnt feature on all our users, I am wondering if you have any examples of user communication on this topic.  I find the Safe attachment feauture straight forward to explain to someone.  However I find the Safe link feature challenging to explain in a non technical manner.  In the past we trained our users to hover over URLS in email to enure its correct, in a way this is reverting that thought back, since all URLS are rewritten.  In additon becuase the Safe links are so long its kind of messy if they recieve a text only email.

Of those who use the feature how has it been from the user perspective and how did you communicate it to them?
