When importing .CSV files of lists of contacts, Is Unsubscribed fields are now required. For SharpSpring 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.
In addition, for every import, the Import Tool now requires that you acknowledge and confirm that your unsubscribed contacts are mapped correctly and that your lists are not purchased.
For more information on importing lists of contacts, refer to Import Tool Overview.
