Gemini How It Works
Your AI agent takes a list of target company domains and runs each one through Hunter to find decision-maker email addresses , CEOs, VPs, heads of department.
Each email gets verified: deliverable, risky, or invalid. Only verified emails move forward. The agent then adds each qualified lead to the right Lemlist campaign based on criteria you define , industry, company size, or role.
Finally, it logs everything to Google Sheets: domain, contact name, email, verification status, Lemlist campaign assigned, and date added. The spreadsheet becomes your source of truth.
Run it weekly with a new batch of domains and your outbound pipeline fills itself.
Connector Orchestration: 3 Connectors, one intelligent agent
Connect Hunter, Lemlist and Google Sheets Connectors so your AI agent finds verified email addresses for target companies, adds them as leads to Lemlist campaigns, and tracks the entire pipeline in Google Sheets. Outbound sales that used to need a 3-person team runs from a single prompt.

Superpowers you didn't know your AI had
The Vinkius catalog gives your agent access to 5,800+ Connectors and the intelligence to combine them. Imagine never logging into another dashboard. Your AI handles the work across all tools, in one conversation. That's what this connectivity layer was built for.
Cross-Platform Intelligence
Your agent doesn't just connect to tools. It understands the relationships between them. Data flows where it needs to go, automatically, with full context preserved across all platforms.
Contextual Reasoning
Each decision your agent makes considers the full picture. It reads CRM data, checks calendars, reviews conversation history, and acts on everything at once. Not step by step. All at once.
Productivity at Scale
What used to take 45 minutes across five different dashboards now takes one sentence. Your agent runs the entire workflow end to end while you focus on decisions that actually matter.
Zero-Config Reliability
No API keys to paste. No webhooks to configure. No YAML to debug. Connect your Connectors once, and your agent handles the rest. Each time, without intervention.
Made for

Your AI agent taps into the entire Vinkius AI Connectors to handle these for you. You describe what you need. It does the rest.

Frequently Asked Questions About This Connector Orchestration
Which Connectors do I need for this workflow?
Three: Hunter, Lemlist and Google Sheets. Connect all three to your AI client before running any prompt from this page.
Does this work with Claude Desktop, Cursor or Windsurf?
Yes. Any AI client that supports the Model Context Protocol works , Claude Desktop, Cursor, Windsurf, Cline and others. Connect the Connectors and paste a prompt.
How many domains can I process at once?
As many as your Hunter plan allows. The agent processes them sequentially and respects API rate limits. Start with 10-20 domains per batch for best results.
Does the agent write the cold email?
The agent adds leads to existing Lemlist campaigns. The email sequence and copy live in Lemlist , the agent handles lead discovery, verification and injection. Write your sequence once, then feed it leads on autopilot.
Is lead data secure?
Connectors authenticate through API keys. Your agent only sees Hunter search results, Lemlist campaigns and Google Sheets you have granted access to. Vinkius does not store your data.
What if Hunter finds no emails for a domain?
The agent logs the domain with 'no results found' in Google Sheets. Some companies have strong email privacy. The agent skips them and continues to the next domain , no interruption.
