The first is that you are actually using your list. The only way that I have ever seen to not get an unsubscribe is to never send an email. If you are not going to use the list why go to the time and effort to build it. So congratulate your self when you get the unsubscribe because you are actually using your list.

The second thing is that someone is opening your email. To unsubscribe they had to at least open the email and click the unsubscribe link. The good thing is that your headline worked and got them to open your email. Now if you are using dishonest headlines, (You have won, your account status, and other headlines along those lines) this is not a good thing and you are reaping what you have sown. If you are using a solid headline that matches your email and it gets opened this is a good thing. Your headline is doing its job.

The third good reason to be glad to get unsubscribes has to do with personality. Now here is a shocker (said with sarcasm dripping from the keyboard) Not everyone is going to like you or your writing style. Those that don't will unsubscribe. The good thing though is that if they don't care for your style you will never build a relationship with them. If you can't build a relationship with them they will most likely never buy from you. So each unsubscribe will make your list more targeted to people who actually like your style and are more likely to respond favorably to your offers that meet their needs.

So now you have three good reasons to no longer dread seeing that people have decided to unsubscribe from your list. Rejoice in the fact that you are actually making your list stronger and more profitable for you in the longer run.
