Create the Gmail label: - In your Gmail, create a label named Action (case-sensitive). --- How to customize this workflow to your needs - Change the AI prompt: Add company tone, extra context, or different reply rules. - Label more intelligently: Add conditions or labels for “Newsletter,” “Meeting,” etc. - Adjust frequency: Change how often the Gmail Trigger polls your inbox. - Add manual review: Route drafts to a team member before sending.
