For this training, I will assume that you already know how to add a link in Wordpress. If it is not the case, just type "link Wordpress" in the search box and you will find many trainings.

Now, the important things. To add an email link on an email adress on your site, it is almost the same thing as a normal link. Let say you want to add a link on your email adress. Write it, highlight it and click on the insert link button.

Then, add "mailto:" in front of your email adress in the URL field and click "add link".
