The Bulk Domain Search lets you enter a list of domains or company names, and download a list of email addresses associated with these domains.
In this article, you will learn how to:
How to upload a list of domains or companies
To use the Bulk Domain Search, you will need to have a list of domain names or company names ready. This list can be in a file (CSV, Excel, Numbers or TXT file), or you can simply copy and paste your list directly into Hunter.
To get started, go to the Bulk section of your account, click on Domain Search, and create a New bulk, by clicking on the orange button at the top right. Enter a unique name for your bulk task, and select your type of input. If your file contains website URLs, select Domain names.
When your data is in a file, make sure the domains or company names are in a single column:
Choose the file from your computer, or drag-and-drop the file directly on the page. Alternatively, you can also copy and paste a list of domains or companies in the text area.
💡 You can process at most 25,000 domains or company names in a single bulk.
Make sure to select the correct Type of input based on the type of data you have available.
👉 If you use company names, make sure to use the correct format for them: you will need to remove additional characters such as LLC, brackets, and slashes, that are not allowing Hunter to extract the correct company name. A good company name is "Company" and not "Company Ltd".
How to apply filters and options
In the filters and options section, you’ll be able to:
Set a maximum number of email addresses per domain or company name: enter the maximum amount of email addresses you want to get for a single domain. The lowest number of emails is 1 per domain, and the highest is 100 emails.
Decide if you want to verify the email addresses or not. The option to verify email addresses is only available when you set a maximum number of emails found per domain to 10 or less.
Include the email sources in the results. If this option is checked, the URLs of the sources will be included in additional columns. Only the active sources where the email address can still be found are returned.
Choose to include the original file columns; this will ensure that your original data will be kept when you download the bulk. Otherwise, Hunter will return a new file exclusively with the data we have found. (This option is available only for CSV uploads).
Choose if you want to only get generic, personal email addresses, or both. A personal email address is an address associated with a specific person at the company, such as "john@company.com". A generic email address is an address associated with a role or function at the company, such as "info@company.com".
Select the departments you want to find email addresses for and set a filter strength (only or in priority).
If Only is selected, the filter will be strictly applied and no email address will be returned if no emails match the departments you selected.
If in priority is selected, the matching email addresses will be returned in priority (based on the department order), but other email addresses could also be returned if not enough emails match the selected departments.
Decide if you only want results with some Required fields, such as Full name, Position or Phone numbers.
Download options
If you choose to verify the email addresses, you will have the option to:
Download only the valid email addresses.
Download all email addresses, including those that could not be verified.
Download the list of domains for which we could not find emails.
The system will tell you exactly how many email addresses have been found and how many credits you will need to download the list.
💡 The download option is available only on a paid plan.
How to import the results as leads
You can directly import your results as Leads and save them in a dedicated list of leads so you can later contact them through Campaigns.
After processing a Bulk Domain Search, simply click the Import button and follow the guided process.
💡 The import option is available only on a paid plan.
How to read your result file
The results can be downloaded in a CSV file. CSV files can be opened with all major spreadsheet software, such as Excel, Google Sheets and Numbers. The file has several columns; let’s have a look at them together:
Email address: the email address found in Hunter
Domain name: the domain associated with that email address
Organization: the company name
Confidence score: an indicator of the estimated deliverability of the email (in %).
Type: the email type will be personal if it's associated with a specific person, and generic otherwise.
Number of sources: the number of sources where you can find that email address on the public web.
Pattern: the most common pattern used for the domain's personal emails.
The file will also contain additional information for every email address, when available:
First Name
Last Name
Department
Position
Twitter handle
LinkedIn URL
Telephone number
Input (the domain or company name provided)
Browsing the Bulk Domain section
You can perform a few different actions in the Bulk Domain Search section and have an overview of all your previously created bulks.
Each bulk created will have a status:
a pending status means that the bulk is still being processed;
a ready status means that your bulk is ready to be downloaded;
The downloaded status means that this bulk has already been paid for and downloaded or imported to your leads. You can export your downloaded bulks as many times as you wish at no extra cost.
There are a few additional actions you can perform in the Bulk Domain Search section:
At the top left of your bulks section, you can filter your bulks by Team member; this allows you to select and see only the bulks created by you or other specific team members.
Sort your uploaded tasks by Bulk title, Status, and Created.
You have the option to search by a specific bulk task at the top right.
See archived bulk tasks by clicking on Archived at the top left.
Managing your existing bulk task
If you enter the single bulk task by clicking on the small arrow beside the bulk title, you can:
Rename your bulk.
Delete a bulk task if it hasn’t been downloaded yet (this is possible with a Pending, Ready, or No Result status).
Archive the bulk if it's been previously downloaded and unarchive it. All Archived files can be accessed from the tabbed navigation Archived.
View history allows you to see the history of your bulk. Anytime you download, archive, restore or rename a bulk task, it will be recorded in the history log.
Bulk Domain Search usage and limits
The Bulk Domain Search functionality can be used with any paid plan. However, you can still upload your file on a free plan and see how many emails we can find and how many credits are needed to download your list. This can help you choose a paid plan.
If you do not have enough credits included in your plan to download the file, you can still choose to download the results anyway and use overage credits within your plan limits.
If you have disabled the use of overage credits, you will see an error message in case your plan doesn't have enough credits available to perform the task.
We count 1 Search credit for 1 to 10 emails returned per domain in the Bulk Domain Search functionality.
The list of email addresses of a Bulk Domain Search can be downloaded multiple times. Only the first download will cost credits.
Limit: Each Bulk Domain Search is limited to 25,000 domains (or company names), and the file should not be over 10 Mb to avoid timeouts.
At most 100 emails can be extracted per domain. This is to encourage our users to build more qualified lists rather than big and low-quality exports.
