Always offer this. Multi-channel lookup: Find a personal email (Tool 3) and a phone number (Tool 4) from the same LinkedIn URL in one go. Cross-reference: If a work email is not found, suggest trying a personal email with their LinkedIn URL, or vice versa. ### Presenting results Always show the email or phone number prominently Include confidence scores and verification status when available Flag catch-all, disposable, or role-based emails as potential issues for outreach ### Rules Never fabricate contact data. Only return what the API provides. Present results clearly. Show the email/phone with all available metadata. Handle failures gracefully. If a lookup returns nothing, suggest alternatives. Ask before assuming. If the request is ambiguous, ask a clarifying question. Privacy and compliance. These tools are for legitimate business outreach only. ### Error handling HTTP CodeMeaningAction200SuccessParse and present the response400Missing required fieldsCheck your request body and retry401Invalid or missing API keyAsk the user to check their API key403No active subscriptionDirect user to upgrade at revoscale.io429Rate limitedWait for Retry-After duration, then retry500Server errorRetry once, then inform user to try later ### Coming Soon Two additional tools are in development: Local Leads Finder -- Scrape Google Maps for local business leads with contact info B2B Database Exporter -- Export enriched contact lists from Apollo's 200M+ B2B database ## Trust - Source: tencent - Verification: Indexed source record - Publisher: dotcomcj2 - Version: 1.0.4 ## Source health - Status: healthy - Source download looks usable. - Yavira can redirect you to the upstream package for this source. - Health scope: source - Reason: direct_download_ok - Checked at: 2026-04-30T16:55:25.780Z - Expires at: 2026-05-07T16:55:25.780Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/cold-email-prospecting-agent) - [Send to Agent page](https://openagent3.xyz/skills/cold-email-prospecting-agent/agent) - [JSON manifest](https://openagent3.xyz/skills/cold-email-prospecting-agent/agent.json) - [Markdown brief](https://openagent3.xyz/skills/cold-email-prospecting-agent/agent.md) - [Download page](https://openagent3.xyz/downloads/cold-email-prospecting-agent)
