Much time has been spent discussing the subject of user engagement lately as it becomes more and more obvious how much of a key role it plays in the current email marketing landscape. For your edification – a few recent related posts from the blogging world:

Twitter have in the past week or two made several important changes that I think are worth mentioning, particularly because of the launch of our new Share section. One thing that I noticed this morning (being one of the lucky 5% of users getting a sneak preview) was the new ability to set up lists (apologies for the link to a slightly out-of-date post, but there’s no more recent information available that I know of, yet) – which for me is a very cool feature I have long wished for. Our own Mr Gareth Langston will be posting more about this later, so I’ll leave the details for him to describe.

Also, as many people are aware, Twitter searches will soon be incorporated into Google search results. What hasn’t been as widely discussed is Microsoft already have a Twitter search up and running – at least for part of the world (NB: I finally got it working by tweaking the URL). Finally, on a technical note, they’ve also introduced support for API versioning, which will allow the introduction of new features more easily than previously, and makes my developer side a happy little geek.

Special mention this week to Marketing Sherpa‘s recently announced 2010 Email Marketing Benchmark Report. It’s not free ($297 for the PDF-only version), but to whet your appetite there is a fairly large executive summary slash excerpt available (16 pages, including several pages for the index). The report itself contains research from 1,493 “real-life marketers” with a plethora of charts, tables, statistics, and advice totalling 283 pages of content: quite honestly the most comprehensive research on email marketing that I know of, especially when complemented by our very own UK email marketing benchmark report. Good stuff, Sherpa!
