ClickMail can import and export LDIF and tab-delimited text files, and import from vCards. LDIF and vCard files contain attribute names and data on multiple-line records. Tab-delimited files are imported and exported by specifying a list of fields in ClickMail. For most purposes, the built-in standard list of attributes works well.
To import a file, either choose the appropriate format under Import in the File menu, or drag and drop the file(s) on ClickMail's icon in the Finder.
Character set encoding
Tab-delimited and LDIF text files are presumed to be encoded in Mac OS Roman, the normal character set used on Macintosh. Files to or from Windows systems encoded in Latin-1 (ISO-8859-1) may be translated with software such as MacLinkPlus. Translation is not needed unless accented characters are present in the file. Mac OS Roman, Latin-1, and UTF-8 all have the same encoding for "regular" (US ASCII, or 7-bit) characters.
vCards are presumed to use Latin-1 (ISO-8859-1) encoding.
