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 to take them off your list.
If you need to see who unsubscribed, simply visit the reporting section in your Benchmark Email account.
