I know this blog is aimed more at the technical aspects of designing for email, but I figured it can't hurt to occasionally blather on about other bits and pieces I've learnt along the way. A technique introduced to me by a colleague some time ago, that I was completely oblivious to (naturally, as a designer.. and not a marketeer) was sending out a special 'spotlight' email, concentrating entirely on one subject (usually a lead article) from a recent newsletter where the recipient definitely didn't read the email (at least, the recipient didn't register in our reports as an open OR a click)
Taking these non-opening non-clicking recipients and sending out an email near guaranteed to get them salivating seemed to increase clicks from those non-clickers by at least 25% if not more. As mentioned before, all newsletter content would be stripped out and the email would 90% focus on the lead article and would mention briefly in passing the other content with the remaining 10%.
Just something to bear in mind, a potential tactic to follow up a newsletter with. Always helps selling the idea to a client if you can increase opens and clicks.. doubly so if it culminates in another lead or two :)
edit: rather fittingly,
@Econsultancy has tweeted tonight about
email marketers ignoring unresponsive customers. So I guess with that in mind, this blog post should really fall under the category of 're-engaging unresponsive customers' - well worth having a read of the Econsultancy blog!
