A blog post by Bronto today talks about UNICEF’s recent list-cleansing and re-engagement campaign with good strategy advice and examples.   This is important right now as in this economy no one wants to wast any resources on sending email to a subscriber who never opens it – especially non-profits. So when a large charitable organization like UNICEF addresses this issue, it acts as a timely reminder for everyone that “the smart marketers are watching their pennies” and perhaps it is time to consider a well designed list-cleansing and re-engagement campaign for your organization.
