Thank you for reaching out to us. I can definitely understand how important it is to ensure that your unsubscribed list is accurate. To better research this, we would like to gather additional information for investigating purposes:
1 - The username to your Constant Contact account,
2 - Examples of contacts that you know should be unsubscribed, but are not on the list,
3 - The file you have exported,
4 - A reference to this post.
You can email us this information to social_support(at)constantcontact(dot)com. Feel free to add any additional information that could possibly assist us. In the meantime, have a great day!
