What are the essential strategies to maintain a clean and engaged email list and mitigate risks associated with list decay and spam filtering?

Maintaining a clean and engaged email list is crucial for successful email marketing. A healthy list ensures higher deliverability rates, better engagement, and improved sender reputation, while a poorly maintained list can lead to increased spam complaints, damaged sender reputation, and reduced campaign effectiveness.

This will allow you to send relevant, targeted emails to each segment which is much more effective than sending generic emails to everyone. For example, if some users prefer emails about new products, you can segment them into a category that receives emails ab....
