If below 85, set neutral. \n- Do not infer gender from last_name. \n- If no valid first_name \u2192 set:\n{\n \"first_name\": \"\",\n \"last_name\": \"\",\n \"first_name_probability\": 0,\n \"last_name_probability\": 0,\n \"gender\": \"neutral\",\n \"gender_probability\": 0\n}\n\n---\n\n**Few-shot Guidance (do not echo back)** \n- `janet.smith@company.com` \u2192 `{\"first_name\":\"Janet\",\"last_name\":\"Smith\",\"first_name_probability\":100,\"last_name_probability\":100,\"gender\":\"female\",\"gender_probability\":95}` \n- `alex.johnson@domain.org` \u2192 `{\"first_name\":\"Alex\",\"last_name\":\"Johnson\",\"first_name_probability\":100,\"last_name_probability\":100,\"gender\":\"neutral\",\"gender_probability\":82}` \n- `michael.jr@service.com` \u2192 `{\"first_name\":\"Michael\",\"last_name\":\"\",\"first_name_probability\":100,\"last_name_probability\":0,\"gender\":\"male\",\"gender_probability\":95}` \n- `patricia_m@techfirm.net` \u2192 `{\"first_name\":\"Patricia\",\"last_name\":\"\",\"first_name_probability\":100,\"last_name_probability\":0,\"gender\":\"female\",\"gender_probability\":95}` \n- `chris.martin@company.co` \u2192 `{\"first_name\":\"Chris\",\"last_name\":\"Martin\",\"first_name_probability\":100,\"last_name_probability\":100,\"gender\":\"neutral\",\"gender_probability\":75}` \n- `taylor.smith-jones@workplace.org` \u2192 `{\"first_name\":\"Taylor\",\"last_name\":\"Smith-Jones\",\"first_name_probability\":100,\"last_name_probability\":100,\"gender\":\"neutral\",\"gender_probability\":67}` \n- `info@hermann-scherer.com` \u2192 `{\"first_name\":\"Hermann\",\"last_name\":\"Scherer\",\"first_name_probability\":100,\"last_name_probability\":100,\"gender\":\"male\",\"gender_probability\":95}`"

"content": "Community Node Disclaimer: This workflow uses KlickTipp community nodes.\n\n## Introduction\nThis workflow automatically generates a personalized **email greeting** for KlickTipp contacts using **OpenAI**, and stores it as a reusable KlickTipp custom field. When a contact is tagged, the workflow creates a suitable greeting such as **\u201cLieber Ren\u00e9,\u201d**, **\u201cLiebe Laura,\u201d**, or a safe fallback like **\u201cHallo Ren\u00e9,\u201d** when the gender is uncertain. It also returns **confidence scores (0\u2013100)** so you can decide whether the detected gender and/or extracted name is reliable enough to use.\n\nThis automation is especially useful for marketers, coaches, creators, agencies, and service-based businesses who want consistent personalization at scale, while keeping messaging safe through confidence-based fallbacks and reducing the need for manual contact cleanup.\n\n## How it works\n1. **Trigger: Contact tagged in KlickTipp** (e.g., `HTML AI greeting for email messaging`)\n2. **Check contact data**\n - If **first name exists** \u2192 OpenAI estimates gender based on the first name.\n - If **first name is missing but email exists** \u2192 OpenAI extracts a first name from the email and estimates gender.\n3. **Filter by confidence**\n - If confidence is high (e.g., **>= 85**) \u2192 allow gendered greeting (**Lieber/Liebe**)\n - Otherwise \u2192 use neutral greeting (**Hallo {FirstName},**)\n4. **Update contact in KlickTipp**\n - Save the final **HTML greeting** into a dedicated custom field (reusable in all email templates)\n - Update the first name if it was extracted from email\n\n## Setup Instructions\n1. **KlickTipp preparation**\n - Create a trigger **tag** (e.g., `HTML AI greeting for email messaging`)\n - Create **custom field**:\n - **HTML AI placeholders | greeting**\n - Add **webhook**:\n - **Activation tag:** `HTML AI greeting for email messaging`\n - **Activation URL:** webhook URL from triggers\n\n2. **Credential Configuration**\n - Authenticate your KlickTipp connection with **username/password** credentials (API access required).\n - Connect your OpenAI account using an **API Key**.\n\n## Customization\n- **Threshold**: increase (stricter) or decrease (more coverage)\n- **Adjust greeting style**: if needed, change \u201cLieber/Liebe/Hallo\u201d to other words and phrases"
