How does CustomMailer find internet addresses in a file when using Match Addresses in File or Extract Addresses from File?
This is discussed in detail in the “Match Addresses in File” section of “Mailing List Tools”. The CustomMailer address extraction process is very robust. It can handle almost any kind of file in just about any format and even works on binary files (as long as they are not encoded or compressed). It will work on plain text files, tab-delimited CustomMailer mailing lists, concatenated emails and newsgroup files, Excel spreadsheets, Word documents, and even your regular email program address books (e.g. Netscape .na2 files).
