Add an Add Labels to Gmail Message action: While editing a workflow, click the plus button between existing blocks. This will open a modal where you can select from Cassidy's pre-configured actions. Choose the Add Labels to Gmail Message action to add it to your workflow.

Rename the action (if needed): If you want to make the action more descriptive or easier to reference as a variable later, enter a new name by clicking on the current name.

Add Gmail connection: If you haven't already, connect your Gmail account to Cassidy.

Toggle on "Add Labels to Trigger Email" (optional): If using in conjunction with "New Email Received in Gmail" trigger, enable this option to automatically add labels to the email that triggered the Workflow.

Enter "Email" (optional): Enter an email ID manually, use a variable from previous steps (such as the message ID from a trigger), or click the list icon to directly search and select an email from those pulled in by the trigger. If "Add Labels to Trigger Email" is enabled, this field can be left empty.

Enter "Labels to Add": Select existing Gmail labels by searching and selecting them, or click the pencil icon to manually enter label names. You can add multiple labels to organize your emails effectively.
