I’ve seen this question far too many times now, it’s time to write a blogpost about it.
The short answer is <pre>, the long is described below.
If you need more information on Notification templates in general, take a look at Travis post:
Take a look at this incident:
As you can see it has a description that spans over several lines.
If we would like to send a notification to our end user upon the creation of the incident using the notification template below…

If you want to change the formatting in any other way, you could always add some inline CSS to the <pre> tag, like this:
And that would result in an e-mail that looks like this:
