The Signature tab is where you build what gets stamped on the email: HTML, Rich Text Format, or plain text, with a full editor and live preview before you save.
You design the signature on an existing rule. Create the rule first (see Creating a Rule), set when it applies (see Setting Conditions and Exceptions), design the content here, then publish (see Publishing and Managing Rules). After publishing, the Google Workspace Agent stamps matching outgoing mail. For the end-to-end flow, see How ExSign for Google Workspace Works.
If you do not want to start from scratch, use one of the built-in Templates: ready-made styles you can drop in and adjust. You can also add your own fonts; see Adding Custom Fonts to ExSign.
To design your signature, navigate to the Actions column and then Edit. Click the Signature tab to proceed.

Placeholders insert each user’s directory values automatically. Write {{LastName}} once in a template, and that user’s last name appears when their signature is stamped.
| Category | Placeholders |
| Identity | First Name, Last Name, Display Name, Initials, Job Title, Department, Company |
| Contact | E-mail, Telephone Work, Telephone Home, Mobile, Fax, IP Phone, Pager, Web Page |
| Location |
Office, Street, P.O. Box, City, State, Postal Code, Country |
| Other |
Description, Notes |
| Custom Attributes | extensionAttribute1 through extensionAttribute15 (confirm for Google Workspace) |
If a user does not have a value for a given attribute, the placeholder can leave a blank gap. Wrap a placeholder in Remove Text (RT) tags so ExSign removes the placeholder and its surrounding text when that attribute is missing. See How to Automatically Remove Blank Placeholders.
Directory data is not always capitalized the way you want. Select a placeholder’s full {{ }} text and apply a Text Transformation:
| Option | Effect |
| Upper | Converts to uppercase |
| Lower | Converts to lowercase |
| Title | Capitalizes the first letter of each word |
| Space | Inserts spacing for readability |
You must select the entire placeholder (for example all of {{LastName}}) before applying a transformation. It will not work on partial text.
Special Characters can also be inserted directly where needed.
