Hi, @Rochelley. This information is available from the imports screen. Mouse over the import in question, and choose the “Download error file” option from the import. Each errored row in the import will contain a brief description of why the error occurred.
Sometimes, contacts are imported successfully, but values aren’t written - maybe it’s a mismatching picklist value, or text in a number field, or something like that. Those will indicate a “warning” in the error text. Rows where you see “error” indicate a contact was not imported successfully, usually due to an invalid email address, or an error in configuring the .csv.
