Before going further, please know, this feature is only available for the Sales Navigator Team and Enterprise users.
Via this feature you can upload a list of accounts (CSV file) and create an account list. Points to take care while uploading the file:
incorrect spellings and unwanted word spaces. For ex: Linked In
wrong formats (please make sure to use exact company names not company URLs)
Your CSV files should contain following criteria:
the file should be in CSV format (comma-separated values)
maximum size of the file should be 10MB
maximum upload size of the accounts is 1000
your file should contain the required account names and other applicable fields
How to add the CSV file
open Sales Navigator
click all filters
click create account list > upload accounts from CSV
map the column headers in your CSV to LinkedIn’s account fields > continue
name your account list > enter the account list description > finish
