Frequently asked
How do I connect Hunter.io to Letaido? +
Copy your API key from Dashboard, then API, in Hunter, and paste it into the Hunter connect card in Letaido. One key covers every action.
Does the agent use my Hunter credits? +
Yes, from your own Hunter plan. Domain Search and Email Finder use one credit when they find an address, a verification uses half a credit, and company search and saving leads use none.
Can a Hunter event start a job? +
Yes. A sequence message being sent, opened, clicked or replied to, a sequence pausing or resuming, or an import or export finishing can start one. The new lead event needs Hunter Leads connected to Zapier.
Will the agent send emails from Hunter? +
Only if a job asks it to. Starting a sequence sends real email, and none of the jobs above does that. Allow all read operations once per app; approve each kind of write once.
Is there a Hunter MCP server? +
Yes. Hunter's remote MCP server is included on every Hunter plan and uses your plan's credits. Letaido is not an MCP server: it connects to the Hunter API itself, mixes Hunter with apps like HubSpot and Google Sheets, and runs on a schedule.
Can I use Hunter AI features through Letaido? +
Letaido uses Hunter's API actions, like finding, verifying and saving emails, not Hunter's own AI tools. Letaido is its own AI agent: describe the job, like contacts for new HubSpot companies, and it runs the lookups.
How is Letaido different from Hunter's HubSpot or Salesforce integration? +
Hunter's own integrations sync leads into your CRM. With Letaido you say which companies to look up and what to do with the contacts, across HubSpot, Salesforce and 62 other apps.
