Email Template Settings

In Email Templates you will see the Settings tab. 

To make using the email template editor easy on you, we now remove all formatting when copying and pasting from outside systems (word, stickies, another website).

Pasted text contains hidden HTML formatting that will not translate properly and is almost impossible to detect and/or fix. You may have experienced this before when pasting from another system -  text you paste looks remarkably different from what you thought it would look like and when you try to format it differently, the editor doesn't function as you'd expect.

Although is is not recommended, you can choose to keep the formatting from an outside system. To change your editor back to the awful way, use the Email Template Settings Tab.
