A great example of a re-engagement campaign sent to inactive users:

You probably heard the news by now that Yahoo will be releasing email addresses that haven’t been used in over 12 months. You can read about it here. Yahoo is now trying to re-engage inactive users, like me, and this email does a good job - it gives a deadline for renewing, offers several links to do so, provides help if needed, and even gives the user a reason to reactivate.

Email marketers can use these same tactics in their re-engagement campaigns - which is so important. Everyone should be reviewing subscriber engagement and cleaning lists to get ready for the holidays. Why not try a re-engagement campaign like this to try to reactivate subscribers who haven’t opened a message from you in the past six months? If you can get them back before the holidays, you could have a customer! And for the ones you can’t re-engage, be sure to suppress them from future sends. They’re no longer interested in your products and services and continuing to send to them can do more harm than good.

Any questions - let me know!
