Relevant Products: Exclaimer Cloud - Signatures for G Suite
Using the recipient rules, you should define whether a signature is used for messages sent to any recipient, internal recipients, or external recipients. However, both inclusions and exclusions are optional.
Where inclusions have been defined, they will be processed before exclusions. For the signature to be applied, it must meet the conditions of the inclusion.
Where exclusions have been defined, the signature will not be applied when the conditions of the exclusion are met.
