-
Paste your API key from Hunter.io. For detailed steps, please see the next section.
-

- Submit the form and click on the download button.
This is how the downloaded CSV might look like:

- Copy the API key.
Please note that the free version of Hunter.io allows only up to 50 API calls per month.
-
The app takes in a CSV with a single column that has names of companies in it, and returns a CSV with a list that has emails which:
- Belong to humans, and are not generic (for instance, it will never return [email protected], or [email protected]. Edge cases yet to be tested).
- Have the most probability of being correct. For best results, it's limited to return only two entries with good confidence score, per company.
-
Sometimes, the app might download an empty sheet, or would miss some entries. This might be because:
- Hunter.io does not have any contacts for that company
- Hunter.io has only generic contacts for that company
-
This version of the app outputs the email, first name (if available) and position (if available) of the fetched contact. Other required information could be found in the body of the request.
