Contact Manager is only available on a Professional plan and only users with Client access can view it.

Many customer management platforms can export your customer list to a CSV file, which can be used to import your contacts into the B12 Contact Manager.

Formatting your CSV file

Your CSV file needs to be formatted correctly to be able to import contacts successfully. You can edit your CSV in any spreadsheet program (e.g. Excel, Numbers, Google Sheets). Just make sure to export it as a CSV file after you make your edits.

Here is a guide for formatting your CSV file:

  • B12's Contact Manager can import customer names, phone numbers, and email addresses. Be sure to delete any additional columns of information included in your CSV.

  • The file must have an email column, as this is the value used by the Email Marketing tool.
    Note: The Contact Manager can recognize duplicate contacts with the same email or phone number and will merge them. It won't merge contacts based on name alone, in case you have multiple contacts with the same name.

  • For best results, your CSV file should use one of the following column heading combinations. Heading capitalization can affect successful importing, as well, so be sure to copy these headings exactly. The columns can be in any order.




First Name

Last Name
