Use CSV Enrichment

Overview

Teams with large contact lists can keep contact data updated with CSV enrichment. Enrichment improves both people and company data, providing the most updated information on names, job titles, location, employment, company funding, and more. CSV enrichment is a great way to leverage the vast amount of data available in Apollo for the most effective outreach to your existing contacts.

Check out the following sections to use CSV enrichment for your people or company data.

100,000 Paths to Enrichment

You can upload a maximum CSV file size of 100,000 total rows. Files with more than 100,000 rows will cause an error. To work around this limit, split large files into smaller separate CSVs.

Check out Apollo plans to see which plans include CSV enrichment or credit packages. Your plan may limit the total number of record enrichments. Enrichment record limits don't reset at the end of your billing cycle. If you'd like to purchase a credit package or upgrade your plan, manage your plan.

CSV enrichment doesn't save contacts to Apollo, but you can separately upload a CSV of contacts.

To enrich a CSV of contacts:

Launch Apollo and go to Data enrichment > CSV.
Click Import CSV.

Under Enrich people, click Edit settings to choose the fields you want to enrich with Apollo data.

By default, all fields are selected. Check the data you want to enrich without impacting your team's setup.
When finished, click Save settings.

Click Select CSV.

Select a CSV file from your computer to upload to Apollo.

File Requirements

At a minimum, your contact CSV file must include one of the following groups of column headers in order for Apollo to successfully enrich your records:

First Name, Last Name, Company URL
First Name, Last Name, Company Name
Contact Linkedin URL
Email

The more data you can provide, the better. This makes it easier for Apollo to recognize the contact or account.

Review your available enrichment credits. Click Increase limits if your team needs more enrichment credits.

Next, map the columns from your CSV to default fields in Apollo. You must map at least one of the following: (first name, last name, company URL) or (first name, last name, company name) or (LinkedIn URL) or (email), but map as many fields as possible to optimize enrichment results.
Click Next.

Choose whether Apollo should enrich email addresses, mobile numbers, or both for contacts. Credit charges will vary depending on your selection.
Click Confirm.

Apollo enriches the data in your CSV and emails you when the file is ready to download. Larger CSV files may take longer to enrich. Click Done, or upload another CSV.

If you opted to enrich both emails and phone numbers, download your enriched CSV file to access new contact data for the following fields:

Email
Enriched work direct phone
Enriched home phone
Enriched mobile phone
Enriched other phone
Enriched corporate phone

Timing is Key

CSV files downloaded prior to February 13, 2025, included data for one enriched mobile number. CSV files downloaded on or after February 13, 2025, include enriched data for all available phone number types.

To access additional phone number types for contacts enriched prior to February 13, you can re-upload your original CSV file. Be aware that re-enriching your CSV file requires you to consume additional credits.

When you get the enriched file, upload the contacts to Apollo to engage with them. You can enroll them in a sequence, add them to a list, reach out with the dialer, or book meetings to engage and win sales — all in Apollo.
