Keeping email subscribers actively hurts your email deliverability.

For the two years I celebrated each increase in our email list. I refused to delete anyone because a large email subscriber count felt like an asset.

Eventually our email open rates fell from thirty percent to twelve percent. Our newsletters began landing in the promo and spam folders of people who wanted to read them.

Mail providers look at how many people ignore your emails to decide if you are sending spam. By keeping thousands of email readers we were telling Google and Apple that our email content was not worth opening.

We finally ran a re‑engagement campaign. Deleted six thousand email users who had not clicked a link in six months. It felt terrible to slash our email list size in half

Within three weeks our email open rates stabilized at forty percent. Our total daily sales from email actually increased. A small email list of buyers will always outperform a massive list of ghost email subscribers.

Regular email list cleaning protects your sender reputation. Keeps your metrics honest. How often do you scrub cold email subscribers, from your marketing lists?
