What happens with unsubscribe requests?
When customers unsubscribe to your email, our system automatically filters them out from your send list and puts them in a master unsubscribe list. From that point forward, you cannot email them again. However, we recommend checking all emails from customers after you've sent out a campaign. If they do not follow the proper procedure by putting the word "unsubscribe" in the subject line, for instance, it's up to you
