Do this to Re-engage your inactive email subscribers And Cleaning Your Email List
1) Define your inactive subscribers
The majority of marketers will gauge inactive subscribers as anyone who has not responded, opened, clicked, or acted on any email sent in the past 6 -12 months. However, I recommend you should decrease the time frame to 60 days or less instead of 6 to 12 months.
In this re-engage phase, you should send them free value or freebies (lead magnet) and redirect them to a quiz funnel to warm up your inactive subscribers again. Those who clicked in to your link, are those who are still interested in your newsletter, therefore, you should take this chance to re-build the relationship. Survey your subscribers, ask them what they would like to learn more or find out what is their opinion of you.
3) Delete “Dead” Email Subscribers
After you launched your re-engage campaign, you will notice some of your “stubborn inactive subscribers” still not engage with your emails. At this stage, deleting them is the only way to solve your problem.
