Label genuine sales leads in Gmail with OpenAI GPT-4.1-mini

## Lead Alert Lite (free) by ReadyUpAgents Flags genuine sales leads in new Gmail with OpenAI (gpt-4.1-mini) and adds an AI/Lead label. Cold pitches, newsletters and other noise are skipped. It only adds a label. It never sends, deletes or drafts email. ### How it works 1. Gmail Trigger checks for new messages every minute. 2. Settings holds your business name, model, lead label name and optional notes. 3. OpenAI returns strict JSON: is_lead, a short summary and a reason. 4. When is_lead is true, the lead label is applied. If it does not exist yet, the workflow creates it first. Invalid AI output is treated as not-a-lead. ### Setup 1. Connect Gmail OAuth2 on the Gmail nodes and OpenAI on *Classify Email*. 2. Edit Settings, send a test email, Execute workflow, then activate. ### Customization The label is created automatically. For a nested label, write the full path in lead_label (default AI/Lead). Change lead_label, openai_model or classification_notes in Settings. Adjust the system prompt on *Classify Email* if your definition of a lead differs.
