[Hunter.io] Domain Search
The Hunter.
Find email addresses associated with any domain
The Hunter.io Domain Search block queries the Hunter.io API to retrieve email addresses associated with a given domain. You provide a domain name or full URL as input, and the block returns a structured list of email addresses found for that domain along with organizational details. If a full URL is passed, the hostname is automatically extracted before the search is performed.
The block accepts two inputs: the domain to search (required) and an optional variable name where the JSON result will be stored. The output includes the searched domain, the organization name associated with it, and an array of email records. Each email record contains the address itself, its type (such as personal or generic), a confidence score between 0 and 100, and available name and position fields for the associated contact.
This block fits into workflows that involve lead generation, sales prospecting, contact enrichment, or outreach preparation. It can be connected to downstream blocks that filter by confidence score, format contact data, or trigger follow-up actions based on the emails and roles returned.

What are the required inputs for this block?
The only required input is the domain field, which accepts a domain name (e.g., example.com) or a full URL. The destinationVar field, which specifies the variable where the JSON result is stored, is optional.
What does the block return?
The block returns a JSON object containing the searched domain, the organization name associated with it, and an array of email records. Each email record includes the email address, its type (e.g., personal or generic), a confidence score from 0 to 100, and optional fields for first name, last name, and position.
Can I pass a full URL instead of just a domain?
Yes. If a full URL is provided as the domain input, the block automatically extracts the hostname before performing the search.
What kinds of workflows is this block commonly used in?
This block is commonly used in lead generation, sales prospecting, contact enrichment, and outreach workflows where email addresses associated with a specific organization need to be identified programmatically.
How can I use the confidence score in my workflow?
Each email in the returned array includes a confidence field with a numeric value between 0 and 100. Downstream blocks in your workflow can use this value to filter or prioritize contacts based on how reliably Hunter.io associates the email with the domain.
