Conditions 

Each condition is built from three parts: a Field (what to check, sender, subject, timing, etc.), an Operator (how to compare it, is equal to, contains, and so on), and a Value (what to match against). 

To add/set conditions, navigate to  under the Actions column and then Edit.

When a rule has multiple conditions, all of them must be true, conditions are combined with AND, not OR. If even one condition fails to match, the signature won't be stamped, full stop. This is the most common reason a signature doesn't appear when someone expects it to. See Understanding the Importance of Conditions for more detail. 

If you need a rule to fire under condition A or condition B (rather than both), create two separate rules instead of trying to express "or" logic within one rule. 

Available Conditions 

The following table details all the conditions and the underlying operators presented by ExSign:

Exceptions

Exceptions override conditions, if a message matches an exception, the rule won't apply even if every condition was satisfied. They use the same Field / Operator / Value structure as conditions, but to exclude rather than include (e.g., an exception on Sender mike@example.com means that sender never gets this signature, even if they match everything else). 

To add/set exceptions, navigate to under the Actions column and then Edit.

If you add more than one exception, you choose how they combine: 

This is worth double-checking when you set it up: it's easy to assume exceptions behave like conditions (always AND), but exceptions let you choose.
