Often I get emails from a copy that I tried their online service and felt it didn't work for me. The emails generally have subject lines similar to "We miss you at..."
I feel like I need to reply to their email with "It's not you it's me."
If I find and click an unsubscribe link will they come stand outside my house hoping I come out and talk to them about getting back together?
Companies, please, you make yourselves look desperate with this site of behavior. It doesn't make me want to come back. It makes me wonder why you are clinging to me and what is wing with your product that you are being for customers.
