You can now send emails that are filtered to subscribers within a specific last open or last click date range!

This makes it easy to run win-back or reactivation campaigns—one final check-in with subscribers who haven't been interacting with your emails before you clean your list.

Now... Whether list cleaning is worth it depends on your situation. Keeping your list tidy is generally a good idea, and removing subscribers who haven't opened in a long time can help maintain good deliverability. But, as with all things, proceed with caution. Open tracking isn't perfect—some email clients block tracking pixels entirely, so those subscribers might look inactive even if they're reading faithfully.

Our recommendation: start conservative. If you're trying to clean up a large list, try sending to subscribers who haven't opened in over a year and ask them to reply if they want to stay on board.
