Marketers hoping to maintain customer relationships should consider implementing a similar re-engagement component to their opt-out process. If you ask appropriately and remind recipients of the value of being on your list, you may find that enough customers will stay to make it well worth asking.

When things are going crazy, take time to get the team together and take a breather and laugh, and get everyone on the same page personally as well as professionally.

Managing opt-outs has always been a tricky issue for marketers.

You should try to get as much information as you can before the customer is gone for good. Were they receiving too many email messages? Are they no longer interested in your product or service? Was the content not relevant enough? You can even provide an empty text box on the Web site in which they can add their own feedback.
