Send a Letter When a Document Is Filled In
Move completed paperwork into a physical follow-up without checking document status manually.
Trigger
Document Placeholder Filled
Triggers when a Google Doc's plain text changes such that a configured placeholder token/pattern is no longer present (i.e., the document has been filled in). This trigger monitors a specific Google Doc and fires when a placeholder pattern that was previously present is no longer found in the document's plain text.
Action
Send Letter
Tool to send a letter via u.s. mail with specified recipient, sender, and pdf. use after confirming recipient and document details. example: send letter(to name='john doe', to address='123 main st, ...', file url='https://...')
