Scenario
You wish to add holiday-themed content to your email signatures, and apply those signatures only during holiday periods. For example, sending signatures with a Christmas banner during December, Eid greetings on festival days, or Pride coloring during June.
Resolution
To send seasonal content in your signature, you can customise how signatures are sent in the following ways:
- Applying a Date/Time trigger to the signature rules.
- Using Server-Side Advanced Rules to attach the signature when trigger text is detected.
- Using the Exclaimer Outlook Add-In to choose a festive signature manually for Client-Side deployment.
- To send both your usual signatures and extra holiday content, adding a limited-time Campaign to your emails.
- To apply holiday branding, or to create holiday-specific visuals such as images, colors, or fonts to replace the signature's usual look, creating and applying a Brand Kit.

Brand Kits are applied to existing signatures. Only the content affected by your optional Brand Kit assets (images, colors, and/or fonts) is changed when you apply a Brand Kit. All other content in your signature stays the same. When you stop a Brand Kit from applying after the holiday is over, your signature returns to its usual look.
We recommend! Create a Brand Kit for your signature's normal look to make switching between regular branding and holiday branding easier. Select the relevant Brand Kit from the drop-down in the Signature Designer to choose the look of your signature in a single click.
