To help explain the scope and approaches used for digital marketing working with the IDM in 2005 I developed a more (too?) detailed definition than the simple one at the start of this post to better scope it and show how digital marketing needs to be closely aligned to broader marketing objectives and activities and involves much more than SEO and inbound marketing. So this is the original definition from 2005 - how should it change now?
Another type of electronic mailing list is a discussion list, in which any subscriber may post. On a discussion list, a subscriber uses the mailing list to send messages to all the other subscribers, who may answer in similar fashion. Thus, actual discussion and information exchanges can happen. Mailing lists of this type are usually topic-oriented (for example, politics, scientific discussion, health problems, joke contests), and the topic may range from extremely narrow to "whatever you think could interest us". In this they are similar to Usenet newsgroups, another form of discussion group that may have an aversion to off-topic messages.
