Any marketing or promotional information we send out does have an unsubscribe link at the bottom. It's considered a Commercial Electronic Message.
Once you unsubscribe, the only emails you'll receive from us moving forward would be our credit score update emails, as these are considered transactional emails. The purpose of these emails is to keep you up to date on changes to your account and credit score.
However, if you would like to change how often we send your transactional credit score update email, you can learn more here: How do I change my email notification preferences?
