Important Information Regarding Imports

The Import Tool uses information from .CSV files and creates contact lists from this information. These files contain only alphanumeric data and are presented in a table format.

When formatting .CSV file content, any .CSV file that you import should be structured similar to the following:
 

First NameLast NameEmailIs Unsubscribed
GalileoGalileig@polymath.com

0

Edwin Hubblespace@extragalatic.com

0

Hipparchus math@trig.com

1


When formatting .CSV files, be aware of the following:

  • Header rows are required. Header rows are necessary for mapping Lead Gen & CRM fields to imported fields.
  • Email fields are required. The Import Tool requires that your .CSV file contain a column mapped to the Email field. You will still need to include the Email column when a contact does not have an email address. 
  • Is Unsubscribed fields are required. For Lead Gen & CRM to successfully import a .CSV file, the file needs one column header that is labeled as Is Unsubscribed. The Is Unsubscribed field should be a boolean field, where 0 is for leads who are opted in, and 1 is for leads who are not opted in.
  • Utilize first and last names. For the import to be successful, a first and last name are suggested in the event that you do not have an email address for that contact. Use both as often as possible.
  • Values must match. When importing custom field values, ensure that they are formatted to match the custom field values. For example, picklist and checkbox values are case-sensitive.
  • When importing data with picklist and checkbox fields, the fields must be present in the file import in order to appear. Ensure that the picklist or checkbox fields in your file exist before importing. Otherwise, the data may not import properly.
  • When importing to a checkbox custom field, the data cannot have spaces between values and commas. An example of this would be value1,value2,value. 
  • When importing contact tags, separate multiple tags in the same cell using a comma. Contact tags are case sensitive. If a contact tag doesn't already exist in your instance, a new one will be created.
