A filter is a particular rule for an expression. Use a pipe character when you want to include filters in the expression. I’ll take the first name example again. In case you don’t have the customer’s first name, you can display a fallback text by using the default filter. So, if the first name field has no value in the system, display friend instead. It looks like this.
If you would like to have more filters for one expression in your HTML-based email, you can combine them easily. To show the value in upper case and still have a fallback text, type the following.
