If you are attempting to upload a .csv file to a Campaign, please ensure your .csv matches the best practices listed below.
- Have the Email column be the first column, in Column A.
- Make sure all column headings match your Merge Fields exactly; the column "FirstName" will not work with the Merge Field {!First}.
- Have an email listed for every recipient; don't include any blank email lines. The upload will stop once it encounters a line without an email address.
- Don't include excess information or extra tabs in your .csv file; if you are not using a column or row, remove it before uploading the .csv file. You should remove any additional tabs as well.
- All files upload must be .csv files. The default file type is usually .xlsx - if this is the case, make sure you choose the file type named "Comma Separated Values (.csv)"
