How do I create a clickable email address?

For clicking on the email address to automatically send an email, you need to specify the link for it that looks like this: mailto:name@email.com 

For example, in the menu block ME203A, in the More tab, you need to specify the required email address in text, then select it, and in the text editor bar above, click on the icon to add a link. In the link field, specify the email address mailto:name@email.com and click on Save.
