Importing Contacts: Potential Errors

When you import a contact list via a CSV file on Evalandgo, here are the possible errors you might encounter and how to fix them.

“An error occurred while reading the file.”

The file could not be read by the application.
Please contact support at the following email address and send us the CSV file so we can analyze it: support@evalandgo.com

“You cannot use the § character in your file header.”


This character is reserved by our system and cannot be present in a CSV file. You need to modify your file and re-import it into the application.

“You cannot have duplicate email addresses (first duplicate found at: row x, column y).”

At least one email address appears more than once in your CSV file. The first duplicate detected by the application is indicated by its position.
You can identify duplicate values in Excel. Note that spaces before or after an email address may prevent proper detection.

“An email address is not in a valid format (row x, column y).”

At least one email address in your CSV file contains invalid characters* or is missing a required character. The first invalid email address is indicated by its position.
*More information: Correct syntax for an email address.

“You cannot have duplicate identifiers (row x, column y).”


At least one identifier appears more than once in your CSV file. The first duplicate detected by the application is indicated by its position.

“The fields to import must necessarily contain the ‘Email’ or ‘Identifier’ field.”


To distinguish one contact from another, an email and/or an identifier must be provided. You need to add an “Email” or “Identifier” field when importing the file.

“You must select at least one field to import.”

No fields have been selected for import. You need to add at least one to proceed with the import.

“The number of fields to import does not match your file (missing column(s)).”


You have selected more fields than there are columns in your file. The number of selected fields must match the number of columns in the file.

“The information in your file could not be associated with contacts. You must provide an email address or an identifier.”


You need to associate a field with an email or identifier column.
