Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “If you have a list of contacts to which you should never send any emails, that’s an important block to add to any segment that you’ll use to send an email, in the form of a but not segment block.”
