When a contact is tagged, the workflow creates a suitable salutation such as **\u201cGuten Tag M\u00fcller,\u201d**, **\u201cHallo Ren\u00e9,\u201d**, or a safe fallback like **\u201cGuten Tag,\u201d** when data is incomplete. It also returns a **salutation quality score (0\u2013100)** to help you decide whether the result is reliable enough to store and reuse.\n\nThis automation is especially useful for marketers, coaches, creators, agencies, and service-based businesses who want consistent personalization at scale, while keeping messaging professional 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 salutation for email messaging`)\n2. **OpenAI: Generate a salutation** using available contact data (name, email, company, location)\n3. **Filter: salutation_quality >= 80** (adjustable threshold)\n4. **Update contact in KlickTipp** by saving found **salutation**\n\n## Setup Instructions\n1. **KlickTipp preparation**\n   - Create a trigger **tag** (e.g., `HTML AI salutation for email messaging`)\n   - Create **custom field**:\n     - **HTML AI placeholders | salutation**\n   - Add **webhook**:\n     - **Activation tag:** `HTML AI salutation 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 a **API Key** .\n\n## Customization\n- **Threshold**: increase (stricter) or decrease (more coverage)\n- **Tone/language**: enforce in the OpenAI prompt if you want consistent output"
