Well, charity: water took an alternate route. Once someone donates to a charity: water project, her money takes a long journey. Most charities don't tell you about that journey at all -- charity: water uses automated emails to show donors how their money is making an impact over time. With the project timeline and accompanying table, you don't even really need to read the email -- you know immediately where you are in the whole process so you can move onto other things in your inbox.
When you want to create a win-back campaign: Develop a series of win-back emails to encourage inactive subscribers to re-engage, and utilize post-sending actions to automatically perform a specific list action on subscribers after they receive the final email in the series. This could be used to update one of their merge fields, move those subscribers to a different interest group, or to remove them from your list completely.
