Address files, which are imported to promio.mail, must be csv-files or txt-files.

• No blank lines (cells can be empty, but the column e-mail must include an address in every line)
• In every column has to be standardised information, which means that first names are all standing in the column “First Name”
• No special characters
• The addresses have to be syntactically correct, e.g. localpart@domain.de
• The file can be a comma separated file or semicolon separated file
