Apply a Signature Based on Sender Domain

In some scenarios, you may want a specific signature to be applied only when emails are sent from a particular domain. This can be configured by creating a Rule in the Crossware Designer Portal that checks the sender’s domain and applies the appropriate signature when the condition is met.


Create a Rule

  1. Sign in to the Crossware Portal and navigate to the Rules section.

  2. Create a new rule (for example, SenderFromCrossware).

  3. On the Builder tab and select Email.

  4. Under Sender, click Select an option and choose Contains.

  5. In Enter a value, type the sender’s domain (for example, crossware365.com).

  6. Click Save & Close to create the rule.

Order Signature Priority

  • Go to the Order of Selection to ensure your rule-linked signature is evaluated before default signatures.


Test the Setup

  • Send a test email from the specified domain.

  • Confirm that the signature is properly appended only when the sender’s domain meets the rule criteria.


Crossware automatically applies the signature based on the sender domain.
