Expressions Introduction

In Mail & Deploy, expressions can be used to supply values to certain functions; expressions can either return constant values (see Constant Values), dynamic values (see Dynamic Values) or values calculated from constant and/or dynamic values (see Calculations). 

Example: You want to filter a datasource field. The list of values you want the field to be filtered to is a list of expressions, which will be evaluated just before the field is filtered.

The language in which expressions are written in Mail & Deploy, is Visual Basic .NET; however, in most cases you will not be required to have a deeper knowledge of the language.
