Batch Enrichment FAQ

Our Batch Enrichment service lets you upload a CSV list of emails or domains and download an enriched list of people or companies respectively. If you have an occasional one-off need for our  Enrichment product then this is the best way of using it. You can access the batch service under your dashboard.


Batches are not charged on a subscription basis, but per row in CSV. The price per line is $0.05 USD, and we round to $5 increments. 

Preparing a CSV

When preparing a CSV file for Clearbit's batch Enrichment tool, keep the following in mind: 

  • The CSV should have at least one header column labeled email or domain containing the emails or domains to be enriched
  • Multiple columns are fine as long as the email or domain column is present
  • If both email and domain columns are found in the CSV, only the email address will be used for enrichment
  • Make sure the file has a .csv file extension


You can find an  example response here. All the attributes we return normally from our API are present in the CSV as columns. Data from the original CSV you uploaded won't be present, but rows will be returned in the same order.

Delayed batches

If your batch gets stuck at ~99% processing for more than 10 minutes then please reach out to and we'll get it fixed.
